The young specimen is, of course, much duller than are the 

 adults ; it shows a moult patch on the head between the ears. 



The mammse were ascertained in 4 oi the females to be 2-3=10. 



The skull is about as large as in arhoreus (condylo-basal length 

 averaging 39-7), but the zygomatic breadth is relatively small, about 

 as in narhadce. The cranial and greatest intertemporal widths are 

 very gi-eat, but the temporal lines ciirve inwards so much posterior- 

 ly that the least intertemporal width behind is, relatively to the 

 condylo-basal length, not much greater than in frugivorus and in 

 relation to the cranial width is 2 % less than in the latter. The 

 temporal lines are quite faintly marked and the supraorbital beads 

 are very weakly developed. Tlie parietals articulate broadly with 

 the supraoccipital above the temporal lines. The palatal length is 

 2i% longer than in European races ; the diastema, anterior palatal 

 foramina and tooth-roAvs all showing increased lengths. On the 

 other hand both post-molar lengths (condyle to m. 3, condyle to 

 bulla) are reduced, the pterygoid fossae in particular being short. 

 The masseteric plate is also rather narrow. From these features it 

 would appear that all the jaw muscles are weak. 



liemarJcs : — This is apparently a very sharply defined local race 

 distinguished from all other Indian subspecies by its peculiar skull 

 and relatively long tail. By its bright dorsal coloration it 

 resembles the form occurring in the southern half of the peninsula 

 and differs from the duller subspecies of Bengal and the Central 

 Provinces. The dark bellied rats collected at Ghatmatha and^ in 

 the Koyna Valley immediately below seem to have no connection 

 with satonp and to have been derived from some other stock.
