type locality of which is Trong in Lower Siam, is undoubtedly found 

 in Tenasserim (it extends also southwards through the Malay Penin- 

 sula and beyond), but how far north it meets gigantea or whether 

 there are local races of either in Middle Burma we do not know, for 

 we have no specimens from between the extreme north of Upper 

 Burma, about Bhamo, and the extreme south of Tenasserim. 



Further, at Trong, a quite distinct form {pyrsonota)^ closely allied 

 to the R. ajlnis of Singapore, is found together with melanopepla . 

 Whether this species extends, changed or unchanged, into Burma, 

 we have no means of judging. 



The very ' scrappy ' nature of our National Collection of working 

 specimens of Indian Mammals is greatly to be deplored, and 1 trust 

 means will be found in the early future to remedy it, but in the mean- 

 time, I venture to think that it is * up to ' the members of this Society 

 to lend a hand to close up some of these gaps, which I have indicated. 



The following is a key to the species and sub-species which in my 

 opinion should be recognised, so far as present material enables as to 

 judge.
