Show 1873.] MR. P. L. SCLATER ON PERUVIAN BIRDS. 779 Otaria stelleri, Schlegel, Faun. Jap. t. 22. figs. 5 & 6? Japan (Arthur Adams). The skull figured by Schlegel has the fifth upper grinder, like the young skull from Japan, which made me think at one time that it was a specimen of Gypsophoca. The second skull obtained from Mr. A. Adams is named " Hali-chaerus barbatus," and said to come from Todonasiri, Japan. It is not a Halichcerus, but is very like the older skull of Halicyon richardi in the British Museum, which we received from the Columbia river in British Columbia; and I am inclined for the present to regard it as the skull of that species. The skull is very like it in size and form and proportion of the bones; but it is much thicker and more solid, which may be the effect of age. The lower jaw is so much thickened, especially on the inner side, that the inflexed lower margin which I considered characteristic of the genus Halicyon is only marked by a slight keel on the lower edge ; but still it is sufficiently marked to distinguish this genus from the Seals of the North Atlantic. The Sea-bears may be divided according to the position and number of their grinders :- I. Upper grinders 6 . 6, the hinder behind the front part of arch ; the fifth grinder of the upper jaw sometimes absent, but its place is left between the fourth and sixth. * Skull elongate ; face long; underfur sparse or none. PHAS-COARCTUS. ** Skull broad; face short; under-fur thick. CALLIRHINUS, ARCTOCEPHALUS, EUMETOPIAS, GYPSOPHOCA, ARCTO-PHOCA. II. Upper grinders 5 . 5, the last before the hinder edge of the front of the zygomatic arch. Zalophus, Neophoca. 5. On Peruvian Birds collected by Mr. Whitely. By. P. L. SCLATER, M.A., Ph.D., F.R.S. Part VII.* [Received October 31, 1873.] The present collection of Mr. Whitely contains fifty-six skins, to thirty-nine species. It is from the same district of the Andes of Cuzco as those last reported upon, but nevertheless contains several species of high interest and five apparently new to science. The following is a list of the species and of the localities in which they were obtained, Mr. Whitely having adopted the admirable plan of affixing a small ticket to each specimen, on which the exact date and locality where it was procured and the contents of its stomach are recorded. The nomenclature is that of the ' Nomenclator Avium Neotropi-calium.' 1SW * Continued from p. 18*. |
