not a Pagophilus, lacking the flattened frontal region, the square 

 palatal border, and extensively ossified narial septum of the lat- 

 ter, while the dentition is considerably heavier. In general form 

 the skull is much more elongated and relatively much narrower 

 than in Phoca vitulina, with markedly weaker dentition. 



Pallas gave the name Phoca ochotensis to a small spotted 

 seal found in the Okhotsk Sea, which he says was especially 

 abundant between "Tanisk" and "Ishiga" (= Tansk and 

 Gichiga of modern maps). His long description is not espe- 

 cially diagnostic, but seems to point to the present species, 

 particularly in his reference to its slenderer and more graceful 

 form as compared with its congeners. His description of the 

 under parts as "subtus maculis subquadratis sparsis, obsolete 

 testaceis, sub collo crebrioribus," is characteristic of the pres- 

 ent species in contradistinction to Phoca hispida gichigensis, 

 the only other form of Phoca known from the Okhotsk Sea. A 

 definite type locality is given by Pallas, at which the present 

 specimens were taken, and which are therefore topotypes. 

 His statement " auriculae externae minutae nigricantes " might 

 seem to indicate an eared seal, but the whole tenor of his de- 

 scription shows conclusively that his Phoca ochotensis is a 

 species of Phoca. 1 - Besides, a minute blackish rim around the 

 ear opening is distinguishable in the present specimens, and 

 in one is quite noticeable. It is doubtless this to which he 

 refers in describing the ear.

Similar in dental and cranial characters to Phoca ochotensis but with 

 much heavier dentition, and the teeth less separated, especially in the 

 lower jaw. The external characters are not known. 



Skull. Similar in general conformation to that of Phoca ochotensis, 



1 That he knew the eared seals is shown by his description of his Phoca leonina (= Eu- 

 metopias jubata = E. stelleri auct.) and Phoca nigra, which latter is based primarily on 

 a young fur seal from the Kurile Islands, recently named Callorhinus kurilensis, but 

 which must apparently be called Callotaria nigra.
