(May to December). May 6, 1902. Prof. G. B. Howrs, LL.D., F.R.S., Vice-President, in the Chair. The Secretary read the following report on the additions made to the Society’s Menagerie in April 1902 :— The registered additions to the Society’s Menagerie during the month of April were 208 in number. Of these 19 were acquired by presentation, 45 by purchase, 19 were born in the Gardens, and 125 were received on deposit. The total number of depar- tures during the same period, by death and removals, was 139. Amongst the additions are the first examples that we have received of the beautiful Grey Teal (Querquedula versicolor) of the Argentine Republic, obtained by purchase at the Antwerp sale, The Secretary called attention to a specimen of Moth of the genus Cossus, which had been sent home in chrysalis by Mr. W. L. Selater, F.Z.8., from the Cape (Feb. 27th, 1901), and had emerged in the Insect-house, as mentioned by Mr. A. Thomson in his Report (P. Z. S. 1902, vol. i. p. 204). Mr. Sclater had sub- Proc. Zoou. Soc,—-1902, Vor. I. No. I. 1 2 MR. OLDFIELD THOMAS ON [ May 6, mitted this specimen to Mr. R. Trimen, F.R.S., who had favoured him with the following remarks upon it :— Ns “On comparison of the specimen with the series in the British Museum, there can be no doubt at all that it is a veritable Cossus ligniperda, ov ‘ Goat-Moth.’ “Tt would be interesting to know the history of this example, for there can be no question that timber-burrowers are carried about the world more than most insects, and it seems possible that the larva of this Cossus may have travelled in logs to the Cape, and been developed there, and so been sent home as a South-African insect. “Tt is also not altogether unlikely that the species may have been introduced into South Africa and have established itself there, as it feeds on several different trees, and the willow (one of its food-trees in Europe) is represented by a closely-allied Salia in South Africa.” The following papers were read :— 1. Onthe Mammals collected during the Whitaker Expedition to Tripoli. By Ouprietp THomas. [Received March 26, 1902. | (Plate I.') Mr. J. 1.8. Whitaker, F.Z.S., who has already done so much for the exploration of the Vertebrate Fauna of Northern Africa, and to whom our National Museum is indebted for important collections of Mammals from Sicily, Tunis, and Morocco, has long wished to send a collecting expedition into the little-known country of Tripoli. Last year, by the kind intervention of the Foreign Office, permission was obtained from the Sultan for Mr. Edward Dodson and a companion, Mr. Drake, to travel through that country, collecting specimens, and it is the Mammalian results of this expedition of which the present paper gives an account. The expedition was carried out entirely at Mr. Whitaker’s expense, and, as in the case of the previous Moroccan expedition, he has generously presented the great majority of the Mammals collected to the National Museum, to which ‘they form a most valuable addition. As so often happens in such cases, the material available for comparison with the Tripoli collection is most imperfect, and badly needs supplementing by specimens collected in modern fashion. Indeed, of Barbary Mammals the only modern specimens are those of Mr. Haton from Biskra, and Mr. Dodson’s own previous collections from Morocco. Zoologists, therefore, who spend their winters in the south would do a great service to ! Por explanation of the Plate, see p. 13.

Mr. Dodson left the town of Tripoli on April 2nd, 1901, and travelled southwards by way of Sokna to Murzuk, then returned to Sokna, and from there travelled north-eastwards to the Syrt district, where he worked eastwards along the coast to Ben-Ghazi. His localities are thus divisible into four groups, as follows :— I. Inland country north of Sokna. March 1901 and middle of June to middle of July. Specimens collected at Tarhuna, Wadi Sofedjin, W.' Nefed; W. Bey; Bonjem; Erdeul; Ain Hammam; W. Titti; W. Agarib; W. Wagis; Oumsinerma ; Limhursuk; Gebel Binsertia. This is a desert region, without marked elevations ; interspersed with small oases. II. Soda Mountain district just south of Sokna (28° 55' N., 16° 15’ K.). Beginning of May and second week of June. Localities. Tamari-Ferdjan; W. Sultan; Getefa; Linzerat. The Soda Mountains rise to about 3000 ft. above the general level of the plain, not high enough therefore to have any noticeable climatic or faunal peculiarity. There is a map of this distinct in Rohlf’s ‘ Kufra’ (1881). III. Level and descending country southwards to Murzuk (sea-level or below). Localities. Shup; Oum el Abid; Zighen ; Sebha; Ghodua; Murzuk. IV. Coast district eastwards from Syrt towards Ben Ghazi. End of July and beginning of August. W. Aggar; Eleusher; Bon Cheifa; Sidi Sweya; Sidi Faradje. From a geographical standpoint, therefore, the region traversed is of a very good representative character. But, zoologically, there must be many more species which, on account of the hurried nature of the march, and the difficulties in collecting in so wild and semi-hostile a country, must have been missed by Mr. Dodson’s party. Indeed, under the circumstances it is surprising how admirable a collection has been made. As might be expected from the position of Tripoli between Egypt and Algeria, and the homogeneous nature of all three regions, the mammals have no marked general aflinity or peculiarity. Some, such as Acomys, Gerbillus pyramidum, G. eatoni, and Dipodillus vivax, are Kgyptian in affinity; and others, notably the Ctenodactylus, are distinctly Algerian ; but these affinities are evidently only the eastward and westward ex- tensions, hitherto unknown, of Algerian and Egyptian forms, and there seems to be no special faunal relationship with either of the two countries more than the other. The proportionate number of new forms in the collection is remarkable, the most notable being the Ctenodactylus and the fine Hare which I have named in honour of Mr. Whitaker, to whose enterprise and generosity the expedition is due, and who is to be congratulated on its very successful outcome. MV o == WW |* 4 MR. OLDFIELD THOMAS ON [May 6, 1, PIPISTRELLUS DESERTI, Sp. n. 71. g. Mursuk. 30/5/1. A small buff-coloured desert ally of P. kuhli, with a particularly small skull. Size smaller than P. kuhli, but the forearm-length not so much less than in that form as to be in proportion with the much smaller skull. General structure, of ears, wings, and dentition, as in P. kuhli. Ears and tragus pale transparent buffy, little darker than the general colour. Wings dark brown, the usual white edging very conspicuous. Interfemoral paler brown, white posteriorly. Colour of fur pale buffy, between cream and pinkish buff of Ridgway, strikingly different from the colour in ordinary kuhli. The hidden bases of the hairs dull slaty. Belly-hairs blackish slaty basally, whitish buff terminally. Skull very small and delicate; the total length, the breadth across brain-case, and the length of the tooth-series, all con- spicuously less than in P, kuhli, whether from Europe, Morocco, Tunis, or Egypt. Dimensions of the type :— Forearm 29°5 mm. Head and body (measured in flesh) 43; tail (do.) 33; ear (do.) 10; third finger, metacarpal 29, first phalanx 10, second phalanx 8:5; lower leg and hind foot (¢.u.) 22. Skull—greatest length 11:6, median length above 10, median length below 9; interorbital breadth 4:1; intertemporal breadth 3'1; breadth of brain-case 62; front of canine to back of m’ 4:3. Type. Adult male. Original number 71. Although with the general characters of P. kuhli, I do not feel justified in calling this Bat only a subspecies of that animal, for other North- African bats of this group, while tending towards P. deserti in colour, show no approach to its conspicuous reduction in size of skull. Hxamples of P. kuhli from Morocco (Dodson), Tunis (Anderson), and Egypt (Anderson), all have skulls of the full normal size. Two names might have been thought to refer to it. Cretzschmar’s V. marginatus from Nubia is paler in colour than usual, but Dr. Anderson’s specimens show that the form from there is of the usual size. Pipistrella minuta Loche', on the other hand, is so far smaller as either to be a totally different form, or, more probably, the young of some indeterminable species. Its locality is in the Algerian range of P. kuhli. 2. Hyana Hymna L. 43. Getefa, near Sokna. 5/5/1. 1 xpl, Scient. Alg. p. 78 (1867). = Pe ——s- Or 1902.] MAMMALS FROM TRIPOLI. 3. CANIS sp.
