Thomas has quite recently published (A. M. N. H. (9) I., 1918, 

 p. 193), a study of the EuiNACKiNiG in which he has restricted 

 Erinaceus to the Palasarctic Region from Spain to China, reviv- 

 ing the genera Hemiechinus, Fitzinger, and Par^echinus, Troues- 

 sart^ for our Indian specie 3. These two genera may be distin- 

 guished as follows, viz:. — 



Key to the genera of the EuiNACEiNiE. 



A. — Spines of the crown coming down 



evenly on to the forehead ... ... I. Hemiechinus.
