In order to show that there is uo appreciable difference in dimensions 

 between the two forms, except perhaps in the size of the bill, which 

 seems to be larger in the eastern bird, I submit the following

Hepatic phase. 



102. Cuculus peniusulse sp. n. 



Diagnosis. — Allied to Cuculus kelungensis Swinh., from Japau, but the gray color 

 much lighter, the under surface, including the under tail-coverts, only 

 very faintly tinged with buff; the under wing-coverts nearly white, with 

 faint and few gray cross-bars, and the inner webs of the primaries with 

 more numerous, broader, white cross-spots, and more white at the base. 

 Dimensions : Total length, 318'"™ ; wing, 197""" ; tail-feathers, 144™™. 

 Type : 9 , U. S. Nat. Mus. No. 89128. 



Habitat : Kamtschatka ; accidental in the Commander Islands. 



Synonymy: 1882. — Cuculus indicus Taczanowski, Bull. Soc. Zool. France, 1882, p. 395 

 (nee Blyth) ; Dybowski, Bull. Soc. Zool. France, 1883, p. 368.

Among the stragglers from the mainland to the Commander Islands 

 I got two female cuckoos, which are quite different from the form de- 

 scribed on a previous page as Cuculus canorus telephonus. One is in the 

 usual gray plumage, while the other represents the hepatic or rufous 

 phase. In those points in which this form differs from the other allies 

 the two skins agree perfectly, leaving no doubt whatever about their 

 belonging to the same species. 



Comparing them with the form mentioned above, I find them to differ 

 in the following poii:ts: 



1. They are considerably smaller. 



2. The under wing-coverts are quite differently marked, the middle 

 and smaller ones being uniform white, without bars, while the inner
