Article X. DESCRIPTION OF A NEW CARIBOU FROM 

 KENAI PENINSULA, ALASKA. 



BY J. A. ALLEN. 

 FOUR TEXT FIGURES. 



In September and October, 1900, Mr. Andrew J. Stone made 

 an important collection of large mammals for the American 

 Museum of Natural History on the Kenai Peninsula, Alaska, in- 

 cluding a good series of Moose (Alces gigas Miller), several 

 specimens each of two species of Bears, and the head of the new 

 type of Caribou here described. Unfortunately the entire ani- 

 mal could not be preserved. In recognition of Mr. Stone's 

 important contributions to our knowledge of the distribution of 

 the large game of northern North America, and particularly of 

 Caribou, it may be called 



Rangifer stonei, sp. nov. 



Type, No. 16701, $ ad., head (skin and skull), Kenai Peninsula, Alaska, 

 Sept. 24, 1900 ; Andrew J. Stone. 



Adult Male, in September. Front of nose back to middle of nostrils, chin, 

 and edges of lower lip grayish or silvery white ; top of the nose, from the white 

 muzzle back to a point opposite the eyes, black, passing into dark (blackish) 

 brown posteriorly and on the sides of the head to below the eyes ; cheeks and 

 throat still lighter brown ; a narrow space surrounding the eye and tear duct 

 grayish ; top and sides of neck dark grayish brown, becoming lighter and 

 grayer at the base of the neck, and then abruptly darker in front of shoulders 

 (skin of body not preserved) ; front of neck white, forming a longitudinal 

 sharply defined band 100 to 130 mm. wide, of greatly lengthened white hair, in 

 strong contrast with the sides of the neck ; the white hair attains a length, 

 along the median line, of 200 to 225 mm. 



Measurements. Mr. Stone's measurements of the animal in the flesh are as 

 follows : Total length 85 in. (=. 2159 mm.); tail, 6 in. (= 152 mm.) ; tarsus, 

 23 in. (= 584 mm.) ; height to elbow, 28 in. (= 711 mm.) ; height to brisket, 

 31 in. (= 712 mm.) ; height to withers, 52 in. ( = 1321 mm.). 



Skull. The skull is narrow and slender in comparison with even that of J?. 

 montanus, and is further characterized by the slenderness of the antlers, especially 

 the narrowness of the palmated portions, and the unusual development of the 

 brow antler and the anterior branch.
