46 Thayer and Bangs, Birds of Saghalin Island. [j "^ 



The name americana is untenable if used with Anas, there being several 

 earlier Anas americana, applied to various Anatidce. Bonaparte's name, 

 Dafila acuta a. americana, Compt. Rend, xliii, p. 650, 1856, just escapes 

 being a nomen nudum, on account of the reference to acuta of Wilson, — 

 the American bird, and could be used so long as the genus Dafila is main- 

 tained. We, however, believe that the American Sprig will have to be 

 known by the name Dafila acuta tzitzihoa (Vieill.) N. D. v. p. 163, 1816, 

 based on Hernandez. The original plate and description are both bad, 

 but without doubt were meant to represent the Sprig which is a common 

 migrant in Mexico. 



*Marila fuligula (Linn.).— One adult male, May 12. Sakachama. 



Falconidse. 



Pandion haliaetus haliaetus (Linn.). — One adult cT, May 17. 

 Sakachama. This skin, presents no differences, that we can detect when 

 compared with European examples. It is, however, rather small, smaller 

 in fact than other east Siberian examples. 



Micropodidse. 



Chaetura caudacuta caudacuta (Lath.). — Two adult females, June 

 11, 1914. Sakachama. 



Cuculidae. 



Cuculus canorus telephonus Heine. — Three adults, two males and 

 female. June 24 to Ju y 8, 1914. Sakachama. 



Picidae. 



Dryobates minor kamtschatkensis Malh.). — One adu c?, 

 May 23, 1914. Sakachama. This specimen seems referable here rather 

 than to either amurensis or minutillus of Butur in, both of which forms 

 however, are so very poorly characterized that without much more material 

 than is available to us we cannot 1 - certain. 



Jynx torquilla japonica Bp. — Five specimens, both sexes. May 9 to 

 June 13, 1914. Sakachama. 



Hirundinidae. 



Riparia riparia ijimse (Lonnb.).^ Eight adults, both sexes, June 10 

 to June 30, 1914. Sakachama. 



This form, as Hartert has already pointed out, is a very strongly marked 

 one. The upper parts are very dark, in some skins almost blackish, and 

 the pectoral band is very dark. The pale edges of the upper tail coverts, 

 scapulars, and feathers of the lower back and rump stand out in marked 

 contrast against this dark ground color and give the form a very charac-
