 C. rex. It differs from the former by its smaller size, by 

 the more definite reversal of the nape-hairs, and by the white 

 stripes ending on the loins and not passing backwards to the

 by its rather larger size and by the white stripes being 

 throughout separated from each other by the median black 

 line. 



Phyllotis sublimis, sp. n. 



A vole-like species of medium size, with short tail and very 

 long fur. 



Size medium ; proportions rather Microtine, intermediate

 General colour dull pale greyish fawn, greyer anteriorly, 

 more distinctly fawn on the sides and posteriorly on the
