122 W. T. Blanford— On Myospalax fuscicapillus, Blyth. [No. 2, 



inner angles, the outer are nearly equi distant, but there is no re-entering 

 angle between the first and second, though there is between the second and 

 third, the posterior termination of the tooth is a very slightly projecting 

 rounded lobe, and it may be noted that each of the upper molars terminates 

 in a somewhat similar lobe, as in Arvicola. 



In the first lower molar there are 4 outer and 5 inner angles, the first 

 on each side rounded and less prominent than the others, the two hinder 

 pairs on opposite sides of the tooth nearly opposite to each other ; the 

 anterior extremity is a rounded lobe, nearly as broad as long, with a very 

 blunt rounded angle inside, in advance of a still blunter one outside. The 

 second and third lower molars have each 3 angles on each side, all nearly 

 opposite to each other, the outer (those to the right in the figure) being 

 in each case a little in advance of the inner. In the second molar the 

 angles inside and outside are nearly equal to each other, in the posterior 

 molar the inner angles are stronger than the outer, and the first outer 

 angle is less prominent than the other two. 



The lower jaw is strong, the coronoid process well developed, the 

 tubercular projection corresponding to the posterior extremity of the lower 

 incisor situated just outside and a little below the condyle, so as to make 

 the latter appear almost double. 



Compared with JEllobius talpinus, the differences presented by the 

 form here described are numerous, but the external distinctions are less 

 striking than those shewn by the skull. E. fuscicnpillus is larger, yel- 

 lower, and rather paler-coloured, and the tail appears a little longer. The 

 base of the fur is much paler, that of E. talpinus being almost black, that 

 of E. fuscicapillus light grey. There are some slight differences too in the 

 feet, e. g., the second toe of the fore foot in E. talpinus appears to be 

 much shorter in proportion to the middle toe than in E. fuscicapillus. 

 The feet too appear larger in the latter but it must be remembered that 

 the comparison is made between dried skins. 



The hinder upper molar in E. talpinus is proportionately much shorter, 

 the two anterior outer angles are close together, and the posterior lobe behind 

 the hindmost outer angle is wanting. The second inner angle too is ill 

 developed or obsolete. In the first tooth of the lower jaw there are only 

 3 distinct external and 4 internal angles, instead of 4 and 5, and the ante- 

 rior lobe is very slightly developed. 



The skulls of E. talpinus in the British Museum (two in number) 

 differ greatly in form from that of E. fuscicapillus and are much more 

 Arvicoline, the facial bones being far less developed in proportion to the 

 brain case, and the occipital crest very small. The zygomatic arch is less 

 high but similar in form and in the arrangement of the bones, the maxillar 

 process, however, is not quite in contact with that of the squamosal
