themselves in the degree to which tlie yellow of the sides of 

 tlie rump is grizzled ov clear, that, with this character shown 

 to be variable, I very mucli doubt if nigriclunis should be 

 considered as distinct from prymnolopha, to which these 

 specimens liave hitherto been referred. 



Dr. Allen * lias also recently tried to show that ^Fi/oprocta 

 pratti, Pocock, is synonymous with Dasyprocta exilis, Wag!., 

 from the Amazon, which has usually been synonymized with 

 j\I. acoiichi/. 



But how he can deduce that '^ I). exU'is belongs evidently 

 to the olivaceous and not to the rufous section of the genus" 

 from Wagler's words " notreo toto castanen-fuscescente " I am 

 at a loss to understand. And the rest of Wagler's description 

 equally applies to M. acouchy, with the quite unimportant 

 exception of the median white stripe on the belly. 



Tlie British Museum contains a Myoprocta from Obidos 

 which is no doubt representative of D. exilis, and this is in 

 all respects similar to typical M. acouchy of Guiana. 



The relation of Allen's M. viilleri, from Colombia, to 

 Pocock's Amazonian M. pratti still remains to be settled. 



XXIX. — A veto Mink-like Mustela/?'o??2 Java. 

 By H. C. Robinson and Oldfield Thomas. 



(Published b}- permission of the Trustees of the British Museum.) 



The animal here described was obtained during 1916 in Java 

 by Robinson, and forms a very striking addition to tlie fauna 

 of that island. It is wndely different from any known 

 Oriental Mustela, but has a very remarkable resemblance to 

 a mink, especially to tlie European one {Mustela lutreola), on 

 which fact we have based its name.
