by himself, and he is certainly entitled to the 

 honor of the new variety bearing his name. So 

 Professor Allen rightly thinks, and though he 

 has adopted Professor Lydekker's name, he re- 

 serves O. pearyi (Allen) as a provisionary one 

 which may be accepted for the Grinnell Land 

 animal in case it should prove to be separable. 

 This, however, does not appear likely. The 

 most distinguishing difference between the O. 

 wardi, as called, or O. pearyi, as it should be 

 known, and the O. moschatus, is in the head. 

 The entire front of the new variety head is more 

 or less gray instead of wholly brown, as is the 

 O. mosckalus ; while the horn base of the new 

 variety is much narrower and slightly different in 

 shape from those of the old variety. The skulls 

 of the two varieties are practically alike ; at least 

 there is very slight difference. The general color 

 of the fur of the new variety is a little lighter, and 

 the animal itself is not so large or heavily built. 



How either variety of musk-ox ever got to 

 Greenland has been a subject of much discussion 

 among scientists who seem now, however, to have 

 finally decided that they reached the island from 

 the west by crossing Smith Sound from Elles- 

 mere Land, and by crossing Robeson's Channel
