At Behring's and the Pribyloff Islands the fur seals are reported to 

 make their appearance from the southward late in spring, and that they 

 only resort to these islands for the purposes of reproduction, and leave 

 them early in the autumn. Their haunts at other seasons seem not to 

 be well known, but it is evident that their winter quarters must be to 

 the southward of these islands. That there is a southward migration 

 of these animals in winter is evident from their reported greater fre- 

 quency at that season on the Pacific coast of the United States. 



Habits. — The very full account of the habits of this species, con- 

 tained in the following communication of Captain Bryant, together with 

 the accompanying notes, require nothing to be added on this point in 

 the present connection.

Discovery. — The group of several small islands, known as the 

 Pribyloff Group, were discovered under the following circumstances. 

 Captain Pribyloff, who in 1781 took charge of the Russian trading 

 factory at Ounalaska, observed during his voyages among the islands 

 to the westward of Ounalaska numbers of fur seals going north in 

 spring and returning in autumn. Believing that there must be un- 

 known land to the northward to which these animals resorted, he fitted 

 out an expedition for the purpose of discovering it, and in June, 1785, 

 while cruising for that purpose, discovered an island. He took pos- 

 session of this island, colonized it, and called it St. George's, from the 

 vessel in which the discovery was made. On a clear day, during the 

 following year, these colonists saw another island to the northward ot 

 the first, and visiting it in their canoes, proceeded to occupy it. The 

 island was called St. Paul's, from its discovery being made on St. 

 Paul's day. 



St. Pauls Island. — St. Paul's Island, of which I append an outline 

 sketch (Fig. 5) is nearly triangular, and sixteen miles in length. Its 

 northern side is a little concave. Its greatest breadth is four miles, at
