152 Mr. W. E. de Winton on the Hares of 



Lepus europcBus occidentalism subsp. n. 



Smaller than L. europceus typicus j colour much warmer 

 and more rufous throughout. 



The difference in the length of the hind foot is perhaps the 

 most constant size character. The difference in colour is 

 most constant in the head and ears and legs. 



I take as the type of tliis subspecies a specimen from 

 Herefordshire, killed on the 7th January, 1898, which I 

 propose to present to the British Museum. 



Measurements taken in the flesh : — 



Head and body 570 millim. ; tail 86 ; hind foot 135, to 

 end of claws and hair 142 ; ear from notch 99, from base at 

 back 120. 



Weight when killed 8 lbs. 6 oz. 



For comparison I give measurements of a Russian hare of 

 quite ordinary proportions (no. 94. 8. 7. 30 in Brit. Mus.), 

 from Lithuania : — 



Head and body (dry skin) (c.) 600 millim. ; tail (c.) 90 ; 

 hind foot (c.) 156, to end of claws 168 ; ear from notch (c.) 

 110, from base at back (c.) 121 without end-hairs. 



The comparative measurements of the skulls given below 

 do not show any striking differences, excepting in the basal 

 length and mandible ; I am, however, unable to say if this 

 greater length would be always found in the Russian hare, 

 but the proportion seeins constant in the specimens examined.
