and full and in excellent condition, and apparently the winter 

 coat. This phase is probably a melanism, comparable to the 

 1 black ' or ' silver gray ' phase of the red fox. 



The ten skulls available for measurement range in total 

 length from 114 to 126 mm., averaging 120, and in zygomatic 

 breadth from 64 to 70, averaging 68. 



"Arctic Fox. Russian local name, Pee-seetz-(a). This is 

 the next common of the foxes in the Gichiga and Anadyr 

 regions. The bulk of the skins come from the country north 

 of Marcova where it is abundant and the commonest form. 

 It prefers the barren tundra to the wooded portions of the 

 country and therefore ranges further northward. More of 

 this species are received at Marcova than at Gichiga and 

 other settlements further south. Pelts are valued at from 

 three to four roubles each. 



"Blue Fox. Russian local name, Gol-o-bah pee-seez-(a) . 

 An occasional pelt is received at Marcova and Gichiga. The 

 one in the collection was caught on a small river flowing into 

 Penginski Gulf. I saw another pelt at Marcova, taken at a 

 place 100 miles northeast of that place. They are valued at 

 15 to 25 roubles each." N. G. B.

 WOLVERENE. 



This species is represented by a skin, without skull, ob- 

 tained by Mr. Axelrod, at Marcova, in the Anadyr Province, 

 and by two young cubs obtained by Mr. Buxton near Kamen- 

 skoi, on Penginski Gulf. The cubs have a total length of 

 about 400 mm. and could have been but a few weeks old. 

 As shown by the skulls, the teeth had not yet pierced the 

 gums. They are, of course, in the soft woolly pelage charac- 

 teristic of extreme youthfulness, and while very different in 

 coloration from the adults, they have the same color pattern. 

 The light areas are pale yellowish white, more strongly yel- 

 lowish on the rump and ventral surface than elsewhere; the 

 dark areas are ashy brown, in strong contrast with the light 

 areas.
