EXTERNAL CHARACTERS. Above gray, darker along the 

 middle of the back, the color varying in different individuals. 

 A specimen from Disco Bay, Greenland (Nat. Mus., No. 8697), 

 is gray, varied with black, but without distinct marks or spots. 

 Wagner describes a specimen from Labrador as clear gray 

 above, marbled with large indistinct yellowish spots, among 

 them one on the back of the head more pronounced 5 sides and 

 whole lower side of the body soiled white. No dark stripe 

 along the back and head. Nilsson describes the color as being 

 a pale gray above, still paler on the sides, and on the belly 

 white ; head and neck above, blackish, with a narrow band of 

 the same color along the back. Macgillivray describes a Green- 

 land specimen as having "the fore part of the head brown, the 

 top light yellowish-gray ; the hind neck and an obscurely de- 

 fined space along the back, including the tail, dull brown, the 

 rest dull yellowish-gray". Mr. Kumlien, who has had the op- 

 portunity of seeing many specimens in the Arctic regions, says 

 the color is variable, the yellowish-brown being "more or less 

 clouded with ligh ter or darker markings, irregularly dispersed ". 

 The length of adult males is usually given as "about ten feet"; 

 females, rather smaller. I find the total length of an adult fe- 

 male skeleton to be 7 feet 2 inches (2195 mm.). 



The young are described as being covered with long, soft, 

 dark gray wool, which, in about two weeks after birth, is re- 

 placed by a coat of shorter, more rigid, bluish-gray hair. Nils- 

 son described a specimen supposed to be foetal as covered with 

 dark gray wool, which is darker on the posterior part of the
