Represented by one specimen, in 'blue' coat, taken April i, 

 1901, at Kamenskoi, on Penginski Gulf; by 4 specimens 

 taken at Marcova, in December, by Mr. Axelrod; by 12 win- 

 ter specimens collected by Mr. Bogoras at the mouth of the 

 Anadyr River, and by 18 hunters' pelts bought by Mr. Bogo- 

 ras of the natives at Indian Point. Of these 35 skins 12 only 

 have skulls, and one only has measurements or indication of 

 sex. This specimen, a male, taken at Marcova, March 10, 

 1901, measures: Total length, 940; tail vertebrae, 345; hind 

 foot, 150. No. 18248, from the mouth of the Anadyr, with- 

 out date, is apparently in summer coat, the pelage being 

 ragged and more or less worn. The general color above is 

 soiled yellowish white, with the underfur dingy gray or gray- 

 ish brown. The ears, and the fur surrounding them, are dull 

 chestnut brown; the nose as far back as the eyes, a broad 

 space enclosing the eyes, and the chin, are dusky brown. The 

 ventral surface is dusky grayish brown, darker and more 

 rusty on the anterior half. The feet and legs are dull rusty 

 brown, the apical portion of the hairs lighter and more yel- 

 lowish. 



The winter specimens are superficially white, or slightly 

 yellowish white, with the thick woolly underfur more or less 

 tinged with gray at base, the amount of gray varying in dif- 

 ferent specimens, from nearly none to a strong infusion. Some 

 of the specimens show a slight mixture of blackish hairs over- 

 topping the general surface. 



The April specimen in 'blue' coat from Penginski Gulf is 

 dull dark brown all over, with a slight reddish tinge, with the 

 underfur light gray, and the soles of the feet whitish. This 

 is the 'blue' fox pelt referred to by Mr. Buxton in his notes. 

 It apparently is not a seasonal condition, as the pelage is long
