Mr. G. E, H. Barrett-Hamilton on 
on July 14th, 1896, and the almost total absence of previous 
records of its occurrence in or about Kamchatka. It is one 
of those birds whose distribution is peculiar; for instance, it 
is not known to breed on the Commander Islands. 
Dafila acuta (Linn.). 
Nos. 40-41. Two unsexed, Karaginski Island, August 23, 
1897. 
— -Mareca americana (Gmelin). 
No. 42. $ , Avacha Bay, July 16, 1896. Weight 1^ lbs. 
Colour of bill, legs, and feet nearly black ; of iris nut-brown. 
As stated above, I believe this is the first known specimen 
of this species from the mainland of Asia. One other is 
recorded by Dr. Stejneger as having been picked up dead 
on Bering Island on May 1st, 1883. 
Fuligula marila (Linn.). 
No. 43. $ , Ukinsk Bay, August 21, 1897. Colour of bill 
bluish horn ; of interior of mouth fleshy ; of iris yellow. 
This species presents us with another instance of the pre¬ 
servation of an identical form throughout a very wide range. 
From Japan southward and also in America it is represented 
by other subspecies. 
Clangula glaucion (Linn.) or C. islandica (Gm.). 
No. 44. $ , Petropavlovsk, August 28, 1897. Colour of 
bill externally horn ; of interior of mouth and bill flesh ; 
of iris yellow ; of legs and feet brownish yellow, w ith the 
webs, claws, soles of the feet, and back of the legs dark. 
It appears to be extremely difficult, if not impossible, to 
distinguish between the females of 0. clangula and C. islandica 
in certain stages of plumage ; but since the latter species is 
not given by Dr. Stejneger as occurring in Kamchatka, my 
Petropavlovsk specimen, although doubtful, is probably the 
former. 
Histrionicus histrionicus (Linn.). [Cosmonetta 
HISTRIONIC A.1 
No. 45. ? , Petropavlovsk, autumn of 1897 ( Mr.Jacobleff ).
