^°|g^^"^] Stejneger, Nerv Species of Guillemot. 20I 



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. carlo. 

 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 snowi, 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. 



Dimensiotis of Type : — Wing, iSi 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.
