 Subfamily 111. — Cricetin.e. 



The Cricetin^ contains three Indian genera which are arranged 

 in a key. by Blanford, as follows ; — 



Key to the genera of the Cricetin^. 



A. — Molars rooted, tubercular I. Cricetulus. 



B. — -Molars rootless, elongate, composed 

 of prisms, 



a. — Ear-conch present 11. MiCROTUS. 



b. — Ear-conch absent HI. Ellobius. 



Gen. I. — Cricetulus. 

 The separation of Cricetulus, as a subgenus, from Cricetus, to 



represent the oriental forms, was proposed by Milne-Edwards in 



1867, and it is now accepted as a full genus. 



No. 309. phceus, Pall. Blanford records a doubt as to 



No. 310. fulvus, Blanf. the validity of these three species, 



^o. 311. isabellinus, deVil. Thomas who has quite recently 



studied them (A. M. N. H. (8). xix, 



p. 452, 1917) concludes that none of these names apply to the 



Ladak form, for which he proposes the name alticola. There is no 



other species. 



Distribution : — 



C. alticola, Thomas. Type locality : — Shushal, I3,500's 



Ladak (Ward — Cr u mp) . 



Other localities :— Ladak ; Upper 

 Sutlej Valley (Whitehead) (B. M.). 

 Type :— B.M. No. 6. 10. 3. 13. 



Gen. II. — MiCROTUS. 

 This genus has been divided into a large number of subgenera 

 of which, however, only five are found in or on the boundaries 

 of our area. They may be placed in a key as follows : —
