NO. 35 NEW MAMMALS — HOLLISTER 7 



chen sind nach Pallas im Sommer dunkel mausefarbig, im Winter 

 weisslichgrau," (Schreber, 1. c, p. 1034). On page 1039, Schrcber 

 says that Pallas found wild reindeer on the Kama and Ufa ; and on the 

 Obi, in the neighborhood of the Berezov Mountains. The last place, 

 as a Pallas Siberian locality known at the time to Schreber, might 

 be regarded as the type locality. 



From our present imperfect knowledge of the Asiatic wild rein- 

 deer, it has been necessary for me to compare the Kamchatkan animal 

 with Doctor Lonnberg's ' sibiricus ' of the Chukchi country, though 

 it is scarcely to be doubted that there is more than the one form of 

 this animal between the extremes of northeastern and northwestern 

 Asia. The size and relative proportions of the Kamchatkan species 

 are best expressed in a table of comparative measurements. In the 

 following I have copied Doctor Lonnberg's measurements of adult 

 male skulls of R. t. fennicus and of R. t. ' sibiricus/ and added the 

 measurements of the type skull of the new species from Kamchatka.
