116 Universify of California Pnhlications in Zoology. [Vol. 7 



in Juneau, most of them probably from Admiralty Island, and 

 they were all similar to the Chichagof heads. So it seems that 

 these differences between the antlers from the northern and 

 southern islands are quite constant ; but I am unable to appreciate 

 any other differences between the deer from the different regions. 

 The skins at hand are not comparable. The Chichagof bucks 

 agree very closely with the description of a Kupreanof buck given 

 by Dr. Allen (1903, p. 528). The principal difference lies in 

 the white half collar on the lower neck, which is in some cases 

 but faintly indicated, and in others entirely absent, leaving the 

 whole neck uniformly brown below the throat. 



Below are the measurements of the seven Chichagof skulls. 

 For the sake of comparison I give the same measurements as 

 those given of the Kupreanof bucks by Dr. Allen, in the paper 

 cited above.
