that incomparable bird cliff on St. George Island, but the ledges on 
St. Matthew are more nearly perpendicular and thus afford less 
favorable nesting cites. 
The lines of drift wood indicate that the island as a whole has 
had a recent elevation, or that some enormous seas which did not 
reach the Pribilofs carried the logs high above tide mark. Some 
logs are about 100 feet above the calm weather water line. 
Hall Island is entirely bold and rugged and has no true beach. 
In fact the top of the island can only be reached in a few gullies 
where small streams empty into the sea. The vegetation and 
character of the upland appeared similar to St. Matthew. 
Pinnacle Island is wedge shaped and has towering spires pro- 
jecting high into the air. It is so steep and rugged that snow does 
not lie upon it. Probably the base of the cliffs might afford a 
landing place in calm weather but whether or not the walls of the 
island could be scaled was not ascertained. 
The action of the ice on these islands seems inconsequential. 
No worn pebbles were found back of the beaches nor are there 
glaciers present. Snow probably remains most of the summer in 
some of the canyons, since it was very deep in places in early July. 
Through the kindly interest of Dr. A. K. Fisher of the Biological 
Survey I am enabled to incorporate in the present list certain 
hitherto unpublished notes taken by him on these islands on 
July 14 and 15, 1899, while a member of the Harriman Expedition. 
Dr. Fisher’s notes, which include four species additional to those 
observed by myself, are inclosed in brackets, and are followed by 
his initials. 
List oF Brrps OBSERVED. 
Gavia stellata. Rep-THRoATED Loon.— The wailing notes of a single 
bird were first heard reverberating from the mountains surrounding a lake 
about the middle of the north shore of St. Matthew. It and two others 
were later collected and the species was afterwards observed in several 
of the lakes. It undoubtedly breeds here but efforts to locate the nests 
were unsuccessful. 
Lunda cirrhata. Turrep Purrin.— Many nesting colonies of this 
species were found on favorable cliffs on both the islands visited. A 
precipitous rock lying off the northwest end of St. Matthew was scaled 
and the burrows of this species found undermining the sod and moss com-
