in different specimens to pale ochraceous, and in the extent 

 of the area thus suffused, which is broadest in those with the 

 deepest suffusion. The ears are more or less yellowish brown, 

 most strongly so toward the base, the depth of the yellowish 

 brown tint correlating with the intensity of the yellow suffu- 

 sion of the dorsal region. 



The skulls show the specimens to be young adults, with the 

 teeth unworn and the sagittal and occipital crests only slightly 

 developed. They range in basal length from 203 to 221 mm., 

 and in greatest zygomatic breadth from 108 to 126 mm., both 

 extremes being females. Compared with the northern forms 

 of American wolves, their small size and the narrowness of 

 the postpalatal fossa attract attention. 



Lack of material prevents comparison of the series of East 

 Siberian wolves with those of other parts of the Palaearctic 

 region. 



"Russian name, Volk. Wolves are extremely rare if pres- 

 ent at all in the Gichiga country. In the Anadyr territory 

 and along the west coast of Okhotsk Sea and inland they are 

 common. The supply of skins received at Gichiga does not 

 equal the local demand for them for making clothing, but at 

 Marcova a few can always be purchased. The people of 

 Gichiga and Marcova recognize but one species, although a 

 priest at Ola assured me that two species were found inland 

 from that place. All of the skins in the collection are from 

 Anadyr." N. G. B.
