2. Paralces gigas (Miller). ALASKA MOOSE. 



Alces gigas MILLER, Proc. Biol. Soc. Wash., XIII, May 29, 1899, 57. 

 Tustumena Lake, Kenai Peninsula, Alaska. 



Six specimens, collected as follows: An adult female, 

 Shesley Mountains, August 24; an adult female and her twin 

 calves, and two young adult males, Level Mountain, Septem- 

 ber 10 1 8, all carefully prepared for mounting. 



These specimens are very dark colored, being nearly black 

 and hence much darker than the eastern Moose from northern 

 Maine and New Brunswick. The two young adult males have 

 small antlers, but mature dentition, although the teeth are 

 still unworn. The measurements of these specimens, taken 

 in the flesh before skinning, are as follows : 



The skulls of the two females (adult but not old, the teeth 

 being but very little worn) measure as follows: Total length, 

 587, 5 78; basal length, 560, 543; naso-occipital length, 353,348; 

 front border of premaxillae to front end of nasals, 260, 250; 

 length of nasals, 108, 102; zygomatic breadth, 191, 200; mas- 

 toid breadth, 141, 152; breadth at fronto-parietal suture 

 (= postorbital construction), 92, 89; length of upper tooth- 

 row, 147, 142; length of lower jaw, 450, 457; height at con- 

 dyle, 157, 146; height at coronoid, 215, 217; lower toothrow, 

 155, 150. The skull of a young male, with complete but 

 unworn dentition, is intermediate in measurements between 

 the two females, while another young male skull of practically 

 the same age is slightly larger than the larger of the two 

 females.
