Siberian specimens do not appear to differ appreciably from 

 Greenland examples, on comparison of series of six or eight 

 skulls of each. Mr. Bogoras, however, informs me that the 

 form occurring in the Okhotsk Sea is considerably smaller than 

 that found along the northeastern coast of Siberia. 



According to Mr. Nelson, the Bearded Seal is "rather com- 

 mon along the Alaskan coast of Bering Sea south to Bristol 

 Bay." Murdoch states that it is not rare at Point Barrow, 

 where it occurs at all seasons, but is most common in summer 

 and autumn. On the Siberian side it ranges southward to 

 the Okhotsk Sea, where several specimens were secured by 

 Mr. Buxton for the American Museum. Mr. Bogoras ob- 

 tained others from the Anadyr coast, northeastern Siberia.

This species is restricted to the North Pacific, and appears 

 to be rare on the Alaskan coast, and rather more common, 

 but not numerous, on the coast of Siberia, occurring as far 

 south, according to Von Schrenck, as the Okhotsk Sea. Pal- 

 las states that it was formerly found at the Kurile Islands.
