January 15, 1901.

Prof. G. B. Howes, LL.D., F.R.S., Vice-President, in the Chair.

The Secretary read the following report on the additions to the Society's Menagerie during the month of December 1900 :

The registered additions to the Society's Menagerie during the month of December 1900 were 211 in number. Of these 91 were acquired by presentation and 16 by purchase, and 104 were received on deposit. The total number of departures during the same period, by death and removals, was 158.

Amongst the additions attention may be specially directed to the seven specimens of Verreaux's Guinea-fowl (Outtera edouardi) presented on December 31st by Mr. J. F. Walker of Bulawayo. Mr. Walker states that this Guinea-fowl is found only, so far as he knows, in the Wankie Hills, a district due north of Bulawayo, and about midway between that city and the Zambesi. Only one specimen of it had previously reached the Society's aviaries (see P.Z. S. 1890, p. 86).

I wish also to direct attention to the valuable series of Indian birds lately presented to the Society by Mr. E. W. Harper, F.Z.S., of Calcutta, consisting of examples of twenty species, all new to the Society's Collection, of which the following is a list.

Mr. W. E. de Winton exhibited a specimen, of the large Grrey Meerkat (Cynictis selousi de Winton), described in the ' Annals and Magazine of Natural History,' ser. 6, vol. xviii. 1896, p. 469, hitherto known from a skull only, obtained near Bulawayo.

The skin exhibited (see Plate L), together with a skull, had been obtained by Mr. P. C. Reid on the west bank of the Linyanti Eiver on the 5th July, 1899. The following description was given :

Size about half as large again as the Bay Meerkat (C. p>eni- cillata) ; body-colour grizzled drab-grey ; hairs of the tail broadly white-tipped ; both fore and hind feet black ; belly buff. The grizzling of the head and body is much coarser tlian in the Bay Meerkat, owing to the broader annulations on the hair, but the pattern on the hairs of the tail is similar in both species. There is an entire absence of rufous in the colouring of the Grey Meerkat, the tips of the under-fur and the broad subbasal band of the

coarser fur being dull buff, and the tail whitish iustead of orange colour. The hands and feet of the larger species are black, while in the suialler they are golden-fawn.

Measurements taken from the dried skin : Head and body 400 millim., tail 230, hind foot 90, ear 30 ; all these figures must be considered only approximate.

Mr. Lydekker exhibited the skull of an English Fox (Oanis wipes) with two perfect canine teeth on each side of the upper jaw (see text-fig. 1). A dog's skull with the upper canine of each side partially divided had been figured on p. 211 of Mr. Bateson's

Skull of Fox showing double canine teeth.

Study of Variation, and the present specimen would seem to indicate a fuller development of the same feature. An instance of the full duplication of the corresponding teeth of both sides was afforded by the skull of a Cat figured on p. 225 of the work cited. The Fox to which the skull belonged had been killed by the South Oxfordshire Hounds. The skull itself was the property of Mr. H, G. Pease.

In describing the collection of Fishes brought home from Lakes Tanganyika and Kivu by the Tanganyika Exploring Expedition, under the leadership of Mr. J. E. S. Moore, Mr. G. A. Boulenger pointed out that the study of this important collection did not modify the conclusions embodied in his first report published in 1898.' The exploration of Lake Kivu had thrown no light on the origin of the Tanganyikan fauna ; the smaller lake had proved to be very thinly populated with Fishes, which all belonged to widely distributed genera, the species showing a mixture of Nile and Tanganyika elements, with two that might prove to be endemic. The list of the Fishes from the two lakes comprised 91 species, 74 of which had been named by the author. The collection now described consisted of examples of 50 species, 26 of which were

The following papers were read :

1. On the Fishes collected by Dr. W. J. Ansorge in the Niger Delta. By G. A. Boulenger, F.R.S., F.Z.S.

[Eeceived January 4, 1901.] (Plates II.-IV.O

Whilst recently staying at Sapelle Station, at the JLinetion of the Ethiop and Jamieson Elvers, Dr. Ansorge has, at ray request, made a small collection of the Fishes, which proves to be of quite an exceptional interest, from the fact that through it representatives of two families are added to the African freshwater fish-fauna, one being even entirely new, an event that has not happened since 1.873, when the late Professor Peters described the genus Pantodon, the type of the family Pantodontidce. I feel extremely grateful to Dr. Ansorge for the trouble he has taken, under difficult circumstances and without better preserving-fluid than common trade-gin.

The collection was made in August and September 1900. Some of the small Perch-like fishes (CicJdida') were caught with hook and line baited with worms. But most of the fishes, including CalamicJithys, the Mormyrs, and the new Phractolcemus, were captured in creels baited with the orange-red fleshy nut of the oil-palm, set at the mouth of the Ethiop River, close to the bank, by Dr. Ansorge's native boy. All these fishes are considered good-eating by the blacks.

I am pleased to add that the examples of the new species have been generously presented to the British Museum by Dr. Ansorge.

1. Calamiohthts calabarious J. A. Smith.

The single specimen contained in the collection, a female measuring 345 milhmetres, with 11 dorsal spines, is extremely remarkable for having a very small, but perfectly distinct sub- operculum. The absence of this bone, verified on a considerable number of specimens, had been regarded as one of the generic characters distinguishing CalamicJithys from Polypterus. The coloration of the specimen is a dark oHve-browu above, gradually shading into a bright yellow beneath ; a large deep-black spot on the pectoral fin.

Every possibility of the presence of a suboperculum indicating a ^ For an explanation of the Plates, see p. 10.

species distinct from Oalamichtliys seems to me removed by the fact that I have carefully compared this specimen with others like- wise from the Niger delta, without being able to detect any other important difference. I look upon it as an atavistic individual anomaly.

4. Notopterus afer Grthr.

Phraotoljiimid^.

The highly remarkable fish discovered by Dr. Ansorge, which I here describe under the name of Phracfolcemus cmsorgii, cannot be incorporated into any of the families known at present. It falls into the suborder Malacopterygii as restricted and defined by me ^, and occupies a position intermediate between the Osteorjlossidce and the Clupeidce. The family Phnictolcemidce may be characterized as follows :

Mouth edentulous, projectile, bordered by the very slender ' Poissous du Bassiu-clu Congo, p. 44 (1901).

premaxillaries and maxillaries. Supraoccipital in contact with the frontals, widely separating tlie small parietals. Operculum and suboperculum well developed; preoperculum small; interoperculum enormous, covering the gular region and overlapping its fellow ; svmplectic absent : only three slender branchiostegal rays ; no pharvugeal teeth. Eibs stout, sessile, nearly completely encirchng the body ; slender epineurals ; no epipleurals ; caudal region very short. "No postclavicle. Pectoral fins inserted Ioav down, folding like the ventrals ; latter with 6 rays.

Phractol^mtjs, gen. n.

Body elongate, subcylindrical, covered with large striated scales ; lateral line complete, formed of a series of straight tubes extending along the entire length of the exposed part of the scales. Head small, strongly ossified, covered with thin skin ; mouth small, proboscidiform, capable of being thrust forward, when at rest folded over and received into a depression on the upper surftice of the head ; a single narial orifice, preceded by a barbel ; eyes small, lateral. Gill-openings narrow, i-estricted to the sides ; gular region protected by the interopercles, that on one side (usually the right) overlapping that on the other side. Eour gills ; no pseudobranchise. Pectoral fins small, with IS rays ; ventrals far back, with 6 rays ; dorsal short, with 6 rays, opposite to the space between the ventrals and the anal ; latter short, with C) rays ; caudal fan-shaped, with 18 to 20 rays ; all the fin-rays articulated. Air-bladder very large, extending as far back as the anal fin. Stomach with 3 pyloric appendages ; intestine extremely long and much convoluted.

5. Phbacxol^mus ansokgii, sp. n. (Plate II.)

Depth of body 5 to 6 times in total length, length of head 6| to 7| times. Head depressed, with very broad, slightly convex interorbital region ; diameter of eye 4| to 5| times in length of head, 3 to 3| times in interorbital widfh ; barbel nearly j length of head. Dorsal with the two anterior rays simple, the other four bifid ; the first ray equally distant from the head and from the root of the caudal ; second ray longest, 1^ length of head. Anal similar to dorsal, but rays shorter, the second or longest only I length of head. Pectoral rounded, a little shorter than head, as long as ventral, which is pointed and equally distant from head and from anal. Caudal rounded. Caudal peduncle compressed, nearly as long as deep, as long as head. Scales large, longitudmally striated, 35 to 37 in a longitudinal series, ff in a transverse series. On the caudal region the scales of the lateral fine and those of the series above it maj bear a central sclerous tubercle (probably a seasonal character). Uniform olive-grey.

very thick, with a wing-like expansiou behind at the base, and begin on the second vertebra, there being besides a strong occipital rib. The frontals are very large and the right extends with its cnrved border beyond the median line, as if overlapping its fellow ; two supraorbital bones on each side ; the parietals are very small, and completely separated by the broad and short sapraoccipital, which does not bear a crest. The pair of large bones covering the throat, the right overlapping the left, and which at first suggest the gular plates of the Poh/pteridce, are to be identified as inter- opercukim ; above the interoperculum two very large suborbitals, covering the hyoraandibular and quadrate, which are thrust forward for the suspension of the feeble mandibular rami, which are dis- connected at the symphysis ; the premaxillary and maxillary bones more slender still and connected by ligament with the mandible. Tiie shoulder-girdle is suspended from the posttemporal close to the opei'culum ; it includes the ordinary elements (clavicular, supraclavicular, coracoid, scapula), but a postclavicular is absent : the mesocoracoid arch is pre^jent, slender ; the coracoids are much smaller than the claviculars, and do not meet on the median line ; 4 pterygials support the pectoral fin-rnys.

Four specimens of this extraordinary fish, measuring from 50
