According to other information, "the bears in question were small, thick-set, of a brown colour, with a white spot under the throat." V. fald-herblanus, with other nominal species, was founded on remains from a cavern in the province of Constautine, Algeria, and is probably not distinct from the existing African form. II. URSUS PRULNOSUS.-Tibetan Blue Bear. Ursus prulnosus, Blyth, Journ. Asiat. Soc. Bengal, vol. xxii. p. 589 (1853); nee Blanford, ibid. xlvi. p. 318 (1877). Ursus lagomglarlus, Prejevalsky, Cat. Zool. Collections of H. M. Prejevalsky, p. 9, no. 1 (St. Petersburg, 1887). This Bear appears to be confined to Eastern Tibet, where it inhabits the neighbourhood of Lhasa. The claws and teeth are of the same type as in U. arctus Isabellinus. Apparently it is always of small size; and is best characterized by the black and white pelage, which is quite different from that of any of the forms here included under U. arctus. III. URSUS SPELCEUS.-Cave Bear. Ursus spelceus, Rosenmiiller, Oss. Foss. Animal, p. 18 (1794). The only other member of the U. arctus group, according to my idea, is the extinct European Cave-Bear, which is undoubtedly entitled to specific distinction. Apart from its huge size, which probably does not much exceed that of the Bear from Kadiak Island, this species is easily distinguished by the cheek-teeth. These are. relatively very large, and the enamel of the molars is thrown into a number of fine corrugations or plications, producing a very complicated pattern. Even more distinctive is the last lower premolar (fig. 1, p. 419), which is relatively short, with the inner tubercles very large, and the first placed more on the inner side than in U. arctus. The frontal region rises very abruptly at the root of the nasals. 4. An Account of the Freshwater Fishes collected in Celebes by Drs. P. & F. Sarasin. By G. A. B O U L E N G E R , F.R.S. [Received March 9, 1897.] (Plate XXVIII.) At a recent meeting of this Society1 I had the honour of reading a paper on the Reptiles and Batrachians of Celebes, based chiefly on the collections formed in 1893-96 by the Drs. Sarasin, and gave a full list of the species known to inhabit that island, together with a discussion of their distribution. In the present paper I will limit myself to an enumeration of the Fishes obtained by the Doctors themselves, because the question of the ichthy- 1 Cf. P. Z. S. 1897, p. 193. |
