appear to exist in the Atlantic [? Atlas] chain of mountains in 

 Morocco, whence it often invades the French provinces." According 

 to other information, " the bears in question were small, thick-set, 

 of a brown colour, with a white spot under the throat." V. faid- 

 herhicums, with other nominal species, was founded on remains 

 from a cavern in the province of Constantine, Algeria, and is 

 probably not distinct from the existing African form. 



II. Uesus PETJiNOSUS. — Tibetan Blue Bear.

 p. 589 (1853) ; nee Blanford, ibid. xlvi. p. 318 (1877).

 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. ardus 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.

Ursiis spelceus, Eosenmiiller, Oss. Poss. 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 compli- 

 cated pattern. Even more distinctive is the last lower premolar 

 (fig.l, p. 419), which is relatively short, with the inner tubercles very 

 large, and the first placed more on the inner side than in U. arctics. 

 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. Boulengek,

[Eeceived March 9, 1897.] 

 (Plate XXVIII.) 



At a recent meetiug of this Society ' 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 wiU limit myself to an enumeration of the Fishes obtained 

 by the Doctors themselves, because the question of the ichthy-
