29 t :Mr. (i. K, II. lianctt-IIaniilton on 



on July 11 til, 189G, and the almost total absence of previous 

 reeords of its occurrence in or about Kamchatka. It is one 

 of those birds whose distri])ution is jicculiar; for instance, it 

 is not knowji to breed on the Commander Islands. 



Dafila acuta (Lirtn.). 

 Nos. 40-41. Two unsexed, Karaginski Island, August 28, 

 1897. 



Mareca AMERICANA (Giuelin). 



No. 42. ? , Avacha Bay, July 16, 1896. Weight U 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 MAKILA (LiuU.). 



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 olaucion (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, with tlie 

 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 C*. 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 



HISTRIONICA.] 



No. 45. ? , Petropavlovsk, autumn of \S97 (M7\ Jacohleff) .
