Page 542 - Halobcena. digging less deeply and making fewer turns in its burrow, and seems to remain therein during the day, being exclusively nocturnal in its habits when near its nest. Lays one egg, as large as a pigeon's, white, and not sharply pointed ; first found by me December 10. I did not succeed in finding any young up to January 10, the date of our departure. I heard much from the whalers and others of the great diving powers of these birds, which their structure certainly seems to indicate, without...

Page 542 - On the first landing of our party at Kerguelen Island, this bird was one of the two most commonly heard at night, and seen fluttering about the hillside. Its note is somewhat similar to the mew of a cat, with a marked rising inflection of sound. It cannot rise from level ground in flight, but, once in the air, flies strongly and rapidly, with a rapidly fluttering motion of the wings, very like the flight of the common English sparrow. It burrows in the same localities as Halobcena.
Page 217 - Each prefrontal bone is traversed close to its anterior extremity by the ends of a strong transverse ridge, which then curve round and pass forwards on the lachrymal and maxillary bones, to subside opposite the ninth tooth. The anterior nasal aperture is not divided by bone. The vomers, separated by a longitudinal suture, appear in the palate between the premaxillaries and the palatine plates of the maxillaries.

Page 595 - I cannot reconcile any Yunnan skin examined by me with Walden's description which calls for a bird with "the cheeks and sides of the neck pure white, and the breast, flanks and ventral region ashy grey." All specimens from Yunnan as well as those from western Szechwan that I have seen have yellow cheeks and sides of the neck, and are strongly washed with yellow all over the under parts, and appear to me indistinguishable from birds from the eastern Himalayas. Zappey, however, took in Hupch and eastern...
