voles, while its molar pattern and narrow toetli are peculiar to 

 itself. On the wliole, it may best be called a subgenus of 

 Evotomys until such time as the whole group is again revised, 

 when it will very probably receive with others the dignity of 

 full generic rank. 



The species may be described as follows : — 

 Size about as in Evotomys glnreolus. Fur soft and loose ; 

 hairs of back about 10 mm. in lengtii. General colour above 

 a light brown, not far from " russet " of llidgway, without 

 the warmer and more reddish tone of true Evotomys. Siies 

 and rump not conspicuously or abruptly greyer than the back. 

 Under surface cream-buff, not sharply defined, and mixed 

 with the slaty of the hair-bases ; throat grey. Ears about as 

 long as the fur, Avell-haircd, brown. Upper surface of hands

 Tail about two thirds of the trunk-lengtii, well-haired, the 

 termniai pencil about 3 mm. in length ; dark brown above, 

 pale greyisii below. 



Skull as described above.

 into a distinct sj)ace ; this tooth has three prominent angles 

 and one additional indistinct one on each side. Anterior
