since the Kurils have been given as the particular habitat of this 
black-winged species. I soon found, however, that not only the pale 
eye ring of the latter was absent but also that the proportions were 
entirely different, in fact that I had to deal with an undescribed 
form more nearly related to Cepphus columba than to C. carbo. 
The latter I did not see at all in the Kurils. The many puzzling 
and contradictory statements regarding Kuril Islands specimens 
by Blakiston and by Seebohm have thus received an easy and 
satisfactory solution. 
It gives me great pleasure to name this species for Capt. H. J. 
Snow, of Yokohama, the distinguished explorer of the Kuril 
Islands. 
Cepphus snow, sp. nov. 
Diagnosis. — No white area surrounding the eye; wings entirely black, 
or with narrow white tips to the larger coverts, forming at most three 
narrow white bands; under wing-coverts smoky gray; black of back with 
a slate-colored gloss; 14 tail-feathers. 
Habitat. — Kuril Islands. 
Type.— U.S. Nat. Mus. No. 159,351. Raikoke Island, Kurils, August 
23, 1896. L. Stejneger coll. no. 7009. 
Dimensions of Type: — Wing, 181 mm.; tail-feathers, 54 mm.; exposed 
culmen, 32 mm.; height of bill at nostrils, 10.5 mm.; tarsus, 33 mm.; 
middle toe with claw, 46 mm.; total length, 344 mm. 
In addition to the type I collected 3 other specimens on the 
Mushir Rocks. I have also examined two specimens from Urup in 
the Science College Museum, Imperial University, Tokyo, through 
the kindness of Dr. Ijima. I remember also to have seen a speci- 
men in the American Museum of Natural History in New York, 
said to have come from Kamchatka. It was probably collected 
by Capt. Snow. When I examined this specimen many years ago 
I took it to be a melanistic individual of C. columba.
