SCIENTIFIC RESULTS FROM THE MAMMAL SURVEY. 399 



with soft bristles or spines. In 9 the belly is pure white through- 

 out ; but it frequently shows a narrow pectoral stripe of slaty hue, 

 and this is expanded in 5 to form a collar. In 5 others, many of 

 the ventral hairs have slaty bases ; and in 1, (No. 2965 S from 

 Pyaunggaung), all the ventral hairs have slaty bases, light tips and 

 those in the middle line show the beginning of a median stripe of 

 buff. Of 14 females examined 11 had 12 mammae, 1 had 11, and 2 

 had 10. 



The specimens from Mount Popa and Pagan have short, thin 

 and relatively very spiny coats ; their tails are rather longer, 

 averaging about 120 per cent, of the head and body length. The 

 average dorsal colour strikes me as being rather paler or yellower 

 than in those from the Chin Hills and the North Shan States. The 

 bellies are pure white or cream ; and although 9 have a more or less 

 evident trace of a pectoral slaty stripe, which spreads out anteriorly 

 to form a collar in one specimen, they are much more uniform in 

 ventral appearance than are those from Gokteik and Pyaunggaung. 

 All the females examined show 12 mammae. 



The specimens from Pegu are also long tailed, the tail averaging 

 121 % of the head and body length. These perhaps are a 

 little duller than in the typical series ; the bellies vary from pure 

 cream to dirty white. The females have 12 mammas.
