Lepus corsicanus, sp. n. 



In general colouring and proportions very similar to 

 L. e. occi'dentaUs, but resembling L. mediterraneiis in having 

 deeper grey bases to the fur generally, and the fur of the back 

 being rusty below the black ring, with grey bases. The eye- 

 ring is very conspicuous, being shown up by a rufous patch 

 on the cheeks, which extends from in front of the orbit to 

 halfway between the eye and ear. This pattern is traceable 

 in other species^ but is not nearly so conspicuous. The nape 

 of the neck is milike any of its allies, being grizzled smoky 

 grey.

 Presented by Lord Lilford. 



Measurements (taken from dry skin) : — 



Head and body 450 millim. j tail 73; hind foot 119; 

 ear 107. 



Skull : greatest length 90 ; greatest breadth 43"5 ; breadth 

 of maxillte below lachrymals 31*2 ; length of nasals, middle 

 line 31*5, greatest length 39*5, greatest breadth 21*5, nar- 

 rowest part 14; intertemp. constr. 15; basal length (c.) 73; 

 length of upper molar series (tooth-sockets) 17'2; depth from 

 top of nasals to palate in front of premolars 21*5, at front of 

 palatal foramina 18*2 ; mandible, length (bone only) from 

 back of condylar process to upperside of back of incisors 65, 

 upperside of back of incisors to angle 59'5 ; greatest heiglit

The breadth of the skull will at once distinguish this form 

 from its near ally L. kabylicus.

Size about that of L. Lilfordi, but in colour closely 

 resembling L. mediterraneus ; the ears, which are still more 

 naked behind than in the latter species, are proportionately 

 longer, as are also the hind feet, and, like that species, the 

 base of the fur is slate-coloured, and on the back the fur is
