40 Milter .1 New .Polar Hare f mm Labrador. 



(original number 1180) ; skull No. 32132, United States National Museum , 

 same locality and collector, no further data (original number 2326). 



General characters. Most like Lepus bangsi (Rhoads) from Newfound 

 land, but with shorter hind foot and longer ears. General color of dorsal 

 surface in summer pelage clear hair brown instead of dull broccoli brown 

 as in L. bangsi. Audital bullee more inflated than in L. bangsi. Differs 

 from the Lepus arcticus Ross of Baffin Land in the completely developed 

 dark summer coat, and apparently in cranial characters also. 



Color. General color of dorsal surface hair brown tinged with bluish 

 gray and frosted with whitish. Head clear, pale, hair brown, lightest 

 on cheeks and darkest on crown and forehead. Ears grizzled black and 

 hair brown anteriorly, whitish posteriorly, black at extreme tip. Sides 

 and rump clear gray (Ridg way, Nomenclature of Colors, PI. II, No. 8). 

 Belly dull white. Hind feet white above, tinged with brown over bases 

 of toes. Front feet white, strongly tinged with brown. Soles of all four 

 feet light umber brown. Tail snowy white. 



Skull. The skull of Lepus labradorius exactly resembles that of L. 

 bangsi except in the form of the audital bullse. These are so much in 

 flated that they rise (when the skull is held upside down) conspicuously 

 above the surface of the basioccipital, and slightly above the level of the 

 highest point of the occipital condyle. In L. bangsi the bullre rise very 

 slightly above the surface of basioccipital, and generally not to level of 

 condyle. The ventral exposure of the bullse is in Lepus labradorius con 

 siderably longer than broad, while in L. bangsi the length and breadth 

 are nearly eCmal. 



Measurements. Type: * hind foot 140; ear from crown 100; ear to tip 

 of hairs 108. Another specimen (No. 14793, U. S. National Museum) : 

 hind foot 142 ; ear from crown 105 ; ear to tip of hairs 110. 



* The type of Lepus bangsi measures : total length 626 ; tail vertebrae 

 63 ; hind foot 160 ; ear from crown 85. (Rhoads.)
