inner side followed by the straight inner edge of the long posterior lobe. 

 On the outer side there are, anteriorly, two weak angles rather close to- 

 gether, then a deep sinus opposite to the second inner angle, and behind 

 this the tooth terminates in a narrow elongate process with two slight 

 angles on the outer side only ; none inside. This process, behind the 

 second inner angle, is half the length of the tooth. 



In the first lower molar the anterior inner and outer angles are almost 

 rudimentary on the crown, but they form distinct folds on the sides of the 

 tooth*. The first three spaces in this tooth are confluent, the first two 

 especially are scarcely separable. The same is the case with the first and 

 second spaces in the second lower molar, and with the second and third 

 spaces in the third ; in the latter case the two are just sufficiently distin- 

 guishable to be counted apart. 



3. Arvicola wynnei. (Teeth, Plate I, fig. B.) 

 Arvicola wynnei, W. Blanford, J. A, S. B. 1880, Vol. XLIX, Pt. II, 

 p. 244. 



Colour above dark rich brown, with a slight greyish tingef ; head 

 rufescent ; lower parts pale brown ; tail the same colour as the back ; feet 

 covered with brown hairs above, soles pale. 



Fur very soft ; hairs very dark leaden grey, nearly black at the base, 

 and for three fourths to four fifths of their length on the back, the tips 

 being rufous-brown in general, some more or less grey ; the terminal por- 

 tion on the lower parts pale brown. No longer hairs on the back ; a few 

 scarcely exceeding the rest of the fur, on the rump. The length of the 

 hair on the back in skins collected in the summer and autumn is half an 

 inch or rather less. 



Ears short and rounded, completely concealed by the fur, thinly clad 

 with long hair on the external surface, and with short brown hair on the 

 inside towards the border ; a tuft of long hair on the anterior edge of the 

 inner surface. 



Whiskers brown, the lower greyish, the longest reaching the ear. 



Feet moderate ; fore feet rather large ; claws long, compressed, white, 

 not overhung with long hairs. Thumb of fore foot short, with a short 

 compressed claw ; the middle toe exceeds the fourth by about half the 

 length of the terminal phalanx ; the fourth is scarcely longer than the 

 second, which extends by about the length of its last phalanx beyond the 

 fifth. In the hind foot the third toe is very little longer than the second, 



* They are not counted in the original description ; but I think that similar folds 

 should he noticed, and they appear to he included hy Blasius. 



t In one specimen preserved in spirits the greyish tinge is wanting, and the 

 colour above dark chestnut.
