Seite 101 - Cope. Synopsis of the Extinct Batrachia, Reptilia, and Aves of North America.
Seite 5 - I am not astonished at the small number of new species that my first two collections contain. The region of the Pacific is comparatively much poorer than that of the Atlantic. This must be attributed to the extreme dryness of the soil ; to the scarcity of vegetation and of insect life ; and to the duration of the winds from the northeast and southwest, which there prevail with great violence.
Seite 37 - They seemed rarely to fly over the water, but to confine themselves to the neighborhood of their burrows, sometimes alighting and again taking wing — very much as if there were legions of bats inhabiting the hill. I never succeeded in satisfying myself as to the object of this constant flight during the night, although I spent much time in watching them, since, so far as my observation extended, there were no night-flying insects whatever upon the island, nor did the structure of the stomachs of...
Seite 88 - Dr. PL Sclater exhibited to the Zoological Society a skin of Chionis minor, "being that of an individual of this species which had been transmitted living to the society by E. L. Layard, and brought from the Crozet Islands by Captain Armson.
Seite 43 - Phocidce were seen during four months' residence on the island. Two of these were thought to be sea-leopards, and two sea-elephants, one of the latter having been captured and preserved, as above stated. Sealers speak of a few scattering fur-seals upon this and H card's Islands, but they have never been found in large numbers.
Seite 6 - The loreal shield is, however, extinguished, and the rows of scales are reduced by one on each side. These specimens simply carry one degree further the modifications already described. Yet, on account of the constancy of these characters, I am compelled to regard these individuals not only as a distinct species, but, on account of the absence of the loreal plate, as belonging to another genus. This is the Calamaria elapsoidea of Holbrook; the Osceola elapsoidea of Baird and Girard.
Seite 95 - Internally, the stomach is deeply rugous, the rugae running for the most part axially, but merging in the upper third into a rough pavement of irregular prominences, produced by transverse sulci crossing the longitudinal. The principal grinding surfaces are, as was to be expected from the external arrangement of muscle, anterior and posterior instead of lateral, as usually is the case. The gizzard contained several pebbles, three as large as a grain of coffee, the beaks of two cephalopods, shells...
Seite 26 - December 14. With their huge whitish beaks, lighter-colored heads (then covered with clotted blood), and disordered dun plumage, they reminded me strongly of vultures. Like vultures, also, they had so crammed themselves that they were unable to rise from the ground, although it was sufficiently rocky and irregular for them to do so with ease under ordinary circumstances. They waddled and stumbled to the sea, swam away, and did not rise into the air until half an hour or more of digestion, and perhaps...
Seite 92 - ... strongly suggestive of the frontal papillose casque borne by the turkey* (Meleagris). Opposite the central concavity in the sinuous border of the side-flap of the hood appears, uncovered by the sheath, about half the aperture of the nostril, oval in outline, with its long axis nearly parallel with, but inclining slightly toward, the rictus. The nostrils are pervious. The eyelids are thickened and everted, during life of a pale pink, whence the name "sore-eyed pigeon.
