and contains forty-nine caudal vertebra-, the largest number, by 

 far, known amongst mammals. As it is rather difficult in theory 

 to regard this extravagant length of the tail as characteristic of 

 the primitive mammalian stock (from which this manis, like 

 all other mammals, is descended), and as a feature which the 

 Long-tailed Manis alone has retained, it is necessary to sub- 

 scribe to the assumption that additional vertebrae of the tail 

 can be formed in differentiation of species. If this be the case 

 with Mams longicaudata, it would apply to other mammalia, 

 and might dispose of several difficulties in classification, such 



as, for example, the origin of the domestic sheep from a 

 relatively short-tailed mouflon. 



The Long-tailed Manis is hairy on the under-parts, and 

 the hair is of a dark brown or blackish grey, with a tendency 

 to a whitish line along the edge of the scaly armature. The 

 White-bellied Manis (M. tricuspis\ whose specific name em- 

 phasises the three-cusped edges of its scales, is rather a pretty 

 little animal, a trifle more normal in aspect than its relations, 

 owing to the relatively larger size of its eyes and its under-coat 

 of soft hair, which is a yellowish white.
