Tol. Ill, No, 1.] Note on a specimen of Felts tristis. 31 



{N.S.-] 



In none of these specimens is there any trace of the first 

 upper praemolar, although A is a young specimen of appi'oxiniutely 

 the same age as that of F, tristis. 



FeLis trzstis, therefore, agrees with F, marmorata in type of 

 coloration, in the form of the tail and in the majority of the 

 cranial characters. Its tail, however, is perhaps relatiyely longer 

 and its colours are darker, its habit is more robust, its size probably 

 smaller, its fur longer, and its anterior praemolar better developed, 

 having two roots. The last is the only certain character of any 

 great importance. But for it — and it is just possible that it may 

 be an individual variation — F. tristis might be regarded as a 

 jnelanoid race of F, marmorata probably from a cold climate.
