shorter and broader, the incisive foramina never reaching to middle of 

 pm. 1. Palatal bridge longer than width of postpalatal fossa. Supra 

 orbital processes of frontals deeply notched anteriorly, upraised and 

 widely flaring. Frontals, at their posterior constriction, remarkably 

 tumid, their anterior plane greatly depressed. 



Summer pelage (fide Ross and Leach (1. c.) and Sabine 3 ), white, 

 " The back and top of the head are sprinkled with blackish brown 

 hair which is banded with white, the sides of the neck are covered 

 with hairs of the same color, interspersed with white. The extreme 

 tips of the ears are tipped with black." — Leach. " In some of the full- 

 grown specimens, killed in the height of summer, the hair was a gray- 

 ish brown towards the points but the mass of fur beneath still remained 

 white, the face and front of the ears were a deeper gray." — Sabine. 



In south Baffin Land, as evidenced by a specimen from Cumberland 

 Gulf, the type form intergrades into the following subspecies : 



3. Lepus arcticus bangsii Rhoads, subsp. nov. Newfoundland Polar 

 Hare. Type locality, Codry, Newfoundland. (Diagnosis as given 

 below.) 



4. Lepus grcenlandicus Rhoads, sp. nov. Greenland Polar Hare. 

 Type locality, Robinson's Bay, Greenland. (Diagnosis as given be- 

 low.) 



Lepus arcticus bangsii,* subsp. nov. Newfoundland Polar Hare. 



Type, Ad. ? , No. 3752 ; Co!, of E. A. & O. Bangs. Collected by 

 Ernest Doane at Codry, Newfoundland, Aug. 3d, 1895. 



Description. — Size equal to L. timidus L., of Southern Sweden, with 

 shorter ears, shorter and broader skull, nasal bones and incisive fora- 

 mina, weaker dentition and narrower frontal breadth anterior to the 

 supraorbital processes. 



Adult summer pelage : entire back and upper sides, including neck, 

 shoulders and outer surfaces of thighs, uniform dark grizzled gray, 

 faintly suffused with tawny. A pinch of hairs from near middle of 

 back shows the following color pattern : under-fur fine, tawny-white 

 basally, becoming tawny at distal end ; over-fur white or black at base

4 Named for Mr. Outrara Bangs, who has done so much in making known the 

 mammal fauna of Newfoundland, and who has there collected the finest study- 

 series of Polar hares that can be found in this country.
