Vol. XIV 1897
STEJNEGER, New Species of Guillemot.
201

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 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 on the larger coverts, forming at most three narrow white bands; under wing-coverts smoky gray; black of back with 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, 32 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 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 specimen 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.
