Tyj)e locality. — Herefordshire, England. 



Geographical distrihution. — England, the Isle of Man and the 

 lower, more cultivated portions of Scotland, north to the Orkney 

 and Shetland Islands, the northern limits of the range much 

 extended artificially ; introduced in Ireland* and Switzerland. 



Diagnosis. — Similar to Lepus europseus europseus, but buffy 

 tints rich and dark, approaching the ochraceous-bufF of Ridgway. 



Colour. — Underfur as in L. europseus europseus, except that 

 the dark portion is more nearly black. Longer hairs with the 

 black tips better developed and the sub-terminal annulations a 

 dark ochraceous-bluff, showing in certain lights a decided tinge 

 of tawny. This tawny becomes clear and tinged with rufous 

 along sides and on inguinal patches, though it is duller and with 

 a decided clay-colour cast on collar. Rump as in L. europseus 

 europseus. Grey winter pelage : all the bufty tints replaced by 

 light grey, the exact shade of which is very uniform in the six 

 specimens examined. It is somewhat paler than the smoke-grey 

 of Ridgway and distinctly more blue, somewhat approaching the 

 grey No. 7, though not so dark. A very slight cream-bufF wash 

 may be detected on cheeks, sides of neck and of shoulders, and 

 on collar. 



Skull and teeth. — The skull averages slightly smaller than in 

 L. europseus europseus, the occipitonasal length rarely attaining 

 100 mm. The teeth, however, are fully as large as in the 

 continental animal. 



Measurements. — Two adults from the Isle of Man : head and 

 body, 538 and 548 ; tail, 67 and 89 ; hind foot, 131 and 134 ; 

 ear from crown, 105 and 110. Type (adult female) : head and 

 body, 570 ; tail, 86 ; hind foot, 135 ; ear from crown, 101. Two 

 adult females from Merton Hall, Norfolk : head and body, 575 

 and 583 ; tail, 80 and 90 ; hind foot, 141 and 135 ; ear from 

 crown, 120 and 98. Adult female (grey pelage) fi'om Pangbourne,
