Although the Tarslus from Banca agrees in the essential points with the 

 other species of this singular genus, which have hitherto been discovered, it exhibits 

 the following pecuharities. It has no intermediate front teeth, and the exterior tooth 

 on each side is, comparatively with the other species, extremely minute. Counting 

 (with Desmarest) one canine tooth on each side, above and beneath, it has only five 

 grinders in each jaw. The ears, instead of rising in an erect position, are placed 

 horizontally backward, and are proportionally short. On its structure and peculi- 

 ai-ities I have further to add the following remarks : — The head, in proportion to the 

 size of the body, is large ; the arch of the forehead rises high, and the occiput is 

 regularly spheroidal. The proximity of disposition and excessive size of the eyes, 

 is equally characteristic in this as in other species. The rostrum, or extremity of
