 42 THE CONDOR ] Vol. IV feed extensively on a green sea-urchin. Quantities of the shells were found well above high water and some on the hills. In all these the oral surface was broken. This echinoderm makes no h01e in the rock as our Californian purple species does, so it can easily be taken at low tide. While on top of Besboro Island, August 6, we witnessed a peculiar perform- ance. A raven was flying around the island high above the water. Every ten or fifteen seconds he folded one wing and fell five or six feet like a tumbler pigeon. While falling he gave a peculiar call, then righting himself continued on his course. Leuc0sticte grise0nucha (Brandt).--The Aleutian leucosticte was found only at Dutch Harbor. June 2 they were seen feeding about the wharves much as the English sparrow does in San Francisco. Two days later several were taken in the low hills on Amaknak, and a single specimen in young plumage was taken near the beach, October 4. Acanthis h0rnemanni exilipes (Coues).--The hoary redpoll was taken but twice, a pair at Golofnin Bay, June 26, and a male on Pathfinder Rock, July 7. Acanthis linaria (Linn.)--The redpoll was fairly abundant in many localities and was usually found in flocks of a dozen or more. Young birds predominated. Occasionally one or two adults were seen. A large flock of old and young were located in an alder thicket on Cape Denbigl and a few were found in the alders of Besboro. The species was also seen at Cape Darby, Fallax Point, Castle Rock and near Dexter. A dead male was found on Egg Island. Calcanus lapp0nicus alascensis Ridgw.--Longspurs were very numerous and probably nesting on Amaknak June 23, and were among the first birds seen at Golofnin Bay June 28. They were also abundant on the tundra plains about St. Michael. Adults and partly grown young were taken near Crater Mountain July  , and at Fallax Point they were seen in flocks August 24. The specimens taken about Dutch Harbor are considerably discolored with coal dust. Amm0dramus sandwichensis (Gmel.).--In the rank grass growin g on the sand spit north-east of Dutch Harbor Sandwich sparrows were very abundant the latter part of June. The species is also abundant on a flat to the westward of Dutch Harbor, near Captain's Bay. Notes under date of June 22 are: "Collected nine sparrows on the sand-spit. They were usually shot from the dead flower stalk of a large umbelliferous plant, the stalk serving as a good marker. Two were shot on the rocks along the beach. Their song was seldom heard, but they were often detected by their call note, a sharp faint 'tsp.' They are rather fearless and in- quisitive. Ovaries and testes were large." On our return trip young birds were taken at Amaknak, October 4. Amm0dramus sandwichensis alaudinus (Bonap.). The western savanna spar- row was taken at Golofnin Bay, Fallax Point, Cairn, Crater Mountain, and on Besboro and Egg Islands. A young bird was taken at Cape Denbigh. The bill in the Norton Bay birds is slightly longer than in birds from California. The tail is also a little longer and there is still a greater difference in the wing measure- ments. The material I have, however, is very unsatisfactory; many being young birds or having the flight feathers greatly abraded. Z0n0trichia leuc0phrys gambeli (Nutt.).--The intermediate sparrow breeds commonly along the shores of Norton Sound in favorable localities. It is also abundant on Egg Island where breeding birds were taken. A specimen in streaked plumage was taken at Reindeer and birds in fall plumage at Cairn. It was found in breeding season at Golofnin Bay. Z0n0trichia c0r0nata (Pall.).--The white-crowned and golden-crowned spar-
