 Neiiroirichus, GCntiier. Proc. Zool. Soc. London, 1880, p. 441. 



Body talpiforin. Tail elongate. Snout long. No.strils in the sides 

 of the terminal naked pad of the snout. Eyes minute. Fore feet 

 broad, but without as falciforme; furnished with long, rather sharp, 

 and somewhat compressed claws. 



Dental formula i, |, ; c, \; pm, f ; m, ^^ total, 36. 



Anterior ujiper incisors broad. Internal basal cusp of second upper 

 molar bilobed. Tympanic bulhv incomplete. 



This genus is very closely allied to the Uroirichuft of Japan, and a 

 diagnoses framed to contrast it with that form could contain only char, 

 acters based on the dentition. All the other characters given above 

 are common to the two genera,^ 



'The dift'orcuces in the number and size of the scales and tulicrcles of the feet, rep- 

 resented in Dr. (Jiiuther's tigures, arc illusive. These parts are practically identical 

 in butii forms.
