Mammals from Northern Peraia. 199 



unfoitunately long vanished from the specimens, but the 

 proportions and skull readily show tliat it is a different shrew 

 from that now described. 



The Trebizond form which I described as C. leucodon 

 ZasiMs* differs still more from normal European G. leucodon 

 both in size and length of tail, and I am now disposed to 

 think it should be recognized as an independent species, 

 whose name would therefore be Crocidura lasia.

 25th March, 1907. B.M. no. 7. 7. 14. 30. Type. 



A member of the N. Iluttoni group. 



External characters as usual, the general colour of the type 

 wood-brown above, rather paler below. 



Skull larger and heavier than that of N. Iluttoni. Superior 

 outline strongly bowed. Nasals short, not broadened in 

 front, evenly but slightly narrowing backwards to the more 

 or less rounded posterior end. Supraorbital ridges very 

 thick and heavy at the postorbital point, abruptly dying away 

 halfway across the parietals. Interparietal fairly large. 

 Bullae as in N. Iluttoni. Molars ratiier small in proportion 

 to the size of the skull. 



Dimensions of the type (measured on the spirit-specimen 

 before skinning) : — 



Head and body 167 mm.; tail 123; hind foot 33 ; ear 24. 



Skull: condylo-basal length 42 ; basilar length 37 ; zygo- 

 matic breadth 27; nasals, length 12 2, breadth anteriorly 3*9,
