18/3.] 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- 

 chcerus 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 the zygo- 



matic arch ; the fifth grinder of the upper jaw sometimes absent, 

 but its place is left between the fourth and sixth. 



* Skull elongate ; face long ; under- fur sparse or none. Phas- 



COARCTUS. 



** Skull broad; face short; under-fur thick. Callirhinus, 

 Arctocephalxjs, 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 * 



[Keceived October 31, 1873.] 



The present collection of Mr. Whitely contains fifty-six skins, re- 

 ferable 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.'
