RESULTS FROM MAMMAL SURVEY. 38 



of brain-case 6*5; palato-sinual length 4*2; front of canine to 

 back of m^ 4.- 4 ; front of p* to back of m" 2-2. 



Hah. — Upper Burma. Type from Mt. Popa, other specimens 

 from Mandalay, Kyauk Myating, Pyanng-ganng, and Maymyo. 



Ty;pe. — Adnlt male. B. M. No. 14. 7. 19. 242. Original number 

 36li. Collected 7th September 1913 by G. 0. Shortridge. 

 Presented to the National Museum by the Bombay Natural History 

 Society. 



This Burmese Pipistrel is readily distinguishable by its long 

 penis-bone, which rivals that of P. abramus, by its p'^ not being 

 wholly crushed inwards out of the tooth-row, and by its i^ not 

 attaining the height of the outer cusp of i\ 



Mr. Shortridge's later collection from the Ohindwin also contains 

 examples of P. paterculus, while I now find that the " Vespsrugo 

 abramus " of my list of Manipur Mammals, 1886. f is likewise the 

 same species. 



Scotozous. 



It seems advisable to follow Mr. Miller in recognising Scotozous 

 as a full geniTS, thus relieving the large genus Pipistrellus of an 

 awkward species which varies in the presence or absence of so 

 otherwise important a tooth as the outer upper incisor. When 

 present the tooth is quite minute, not attaining to the height of the 

 cingulum of i\ 



The specimens of 8cotozous dormeri tend to divide into two by the 

 greater or less length of the tooth-row, but the difference hardly 

 justifies specific distinction. At the same time, however, there is 

 some colour variation, the great mass of the specimens from the 

 Bombay area being browner, while there are grey forms both to the 

 north-west in Kathiawar, etc., and to the south-east at Bellary. 

 The latter is typical dormeri, and the former may be distinguished 

 as a subspecies. 



Scotozous dormeri cauriims, subsp. n. 



Size, as gauged by skull and teeth, comparatively large. Colour 

 hoary grey. 



General colour of type above sepia brown broadly washed with 

 hoary grey, the brown without any tinge of chestnut or cinnamon 

 in it. Undersurface similar but paler, the light ends to the hairs 

 broader and generally whiter, though in some specimens they are 

 deep yellowish. 



Skull and teeth larger than in typical dormeri. 



Dimensions of the type : — 

 Forearm 36 mm.
