Three male and two female specimens of this species were collected by 

 Mr. N. Kuroda from a widgeon (Maleca penelope), from a falcated teal 

 (Eunetta falcata) and from a Mallard (Anas loschas), all which birds were 

 captured at Haneda in the suburb of Tokyo. Further were obtained a 

 young male from a skin of Hooper swan (Cygnus musicus, collected in Seoul, 

 Korea, March 1895) and a single female from a Japanese green pheasant 

 (Phasianus versicolor, from Prov. Iwashiro). Probably the latter case was 

 one of a straggler, transmitted from the game-bag in which the host bird 

 was carried. 



This common and very widely distributed species is exceedingly 

 variable. With regard to the dimensions of body and the number of long 

 hairs in the posterior angles of metathorax, the specimens before me closely 

 resemble the form which was obtained by Professor Kellogg from Charito- 

 netta albcola, Anas boschas, and Erismatura rubida. Their measurements 

 are as follows : —
