Am. p. 646 (1874). Hab. The North Pacific, between Alaska and Kamtschatka, where it is very abundant, breeding in thousands on the Prybilov Islands. This is a very distinct species, and may at once be recognized by its very short stout bill, orange-red legs and feet, and dark mantle ; the ground-colour of the primaries is also dark grey. I am indebted to the liberality of the authorities of the Smithsonian Institution for a fine specimen of this species, which is as yet rare in collections. A variation in the hind toe and nail, similar to that in R. tridactyla, although in a smaller degree, is observable in this species. My own specimen has no claw on the right hind toe, and only a minute black speck on the left; of two others, from Alaska (e Mus. Salvin & Godman), the one has no hind nail whatever, whilst the other has small black nails, unequal in size, on both hind toes. Genus LARUS. 4. L A R U S GLAUCUS, Fabr. Larus glaucus, O.

Arctic regions; seldom breeding much to the south of the arctic circle. In winter it goes southwards, and has been known to straggle as far as the Mediterranean, to Long Island on the Atlantic coast of America, also on to the coasts of Japan, whence I have seen specimens obtained at Hakodadi by Capt. Blakiston. |
