22 MAMMALIA. 



Bison bonasus has been found abundantly in Pleistocene 

 deposits in Britain and on the continent of Europe. A form 

 indistinguishable from it occurs in beds of approximately the same 

 age in Arctic North America (Lydekker, Cat. Foss. Mamm. 

 Brit. Mus., Part ii., p. 25, 1885), and we have evidence of its 

 occurrence in the Cromer " Forest Bed." 



Bison bonasus still survives in Central Europe. 



Genus OVIBOS, Blainville. 



OVIBOS MOSOHATUS, ZIMMEBMANN. 

 (Musk Ox.) 



Prof. W. Boyd Dawkins CQuart. Journ Geol. See, Vol. 

 XXXIX., p. 575, Woodcut, 1883) described a portion of the 

 skull of a Musk Ox which had been found at Trimingham, and 

 which there is every probability came from the " Forest Bed." 

 The specimen was found by a fisherman, and formed part of the 

 collection of the late Rev. F. Buxton. 



A second specimen preserved in the University Museum of 

 Zoology and Comparative Anatomy at Cambridge, was afterwards 

 noticed by the same author (Quart. Journ. Geol. Soc, Vol. 

 XLI., p. 242, 1885), and believed to be of Forest-bed origin, 

 although it had apparently been dredged from the North Sea. 



The occurrence of Ovibos moschatus in British Pleistocene beds 

 has been recorded by Sir R. Owen (Quart. Journ. Geol. Soc, 

 Vol. XII., p. 127, 1856), by Prof Boyd Dawkins (Brit. Pleist. 

 Mamm. Pal. Soc, 1872), and by Mr. W. Davies (Geol. Mag. Dec. 

 2., Vol. VI., p. 246, 1879). Its geographical range in Pleistocene 

 times was throughout the northern parts of Europe, Asia, and 

 America, It is now living in Arctic North America and Green- 

 land. 



Genus CAPROVIS, Hodgson. 



CaPEOVIS SaVINII, NEWTON. 



(Vert. Forest Bed, p. 49. Plai-b X.) 



The remarkable horn-core and frontal bone to which the above 

 name was given was obtained from the Forest-bed at Overstrand, 

 near Cromer, and is in the collection of Mr. A. Savin. Nothing 

 has since been found which would throw more light upon the 

 structure of this peculiar form.
