CATALOGUE OF THE CETACEA. 307 
The only fossil remains of whales found up to this time on this coast, are a portion of a 
ramus of a lower jaw (described by Cope, Proc. Phil. Acad. 1872, as Eschrichtius Davidsoni), 
obtained in digging a well at San Diego, California, and presumed to be of miocene age ; a caudal 
vertebra obtained by me in the miocene sandstones of the Shuniagin Islands, Alaska ; and some 
remains of cervical vertebra? and the adjacent portions of the skull, very much injured, obtained 
from the Tertiary sandstones, near Point Conception, California, by Mr. George Sceva ; these, as 
far as their characters are apparent, resemble Megaplera. 
The following Cetacea, mentioned by Captain Scammon, are not at the date of this paper 
represented by material sufficient to indicate their zoological position j 
Grampus, Panama. Grampus, San Diego Bay. 
Grampus, Puget Sound. Scrag Eight Whale, northern seas. 
Grampus, Bottlenosed. 
The other marine mammals mentioned, are the "Walrus (Rosmarus obesus, Illiger); the Leopard 
Seal, pi. xxii, fig. 1 (Phoca Pealii? Gill); the Banded Seal, pi. xxi, fig. 2 ( Histrioiihoca equestris, 
Gill); the Fur Seal, pi. xxi, fig. 1 (Callorhinus ursinus, Gray); the Sea Lion, pi. xx, fig. 2 (Eume- 
topias Stelleri, Gill); the Sea Elephant, pi. xx, fig. 1 ( Macrorhinus angustirostris, Gill); and the 
Sea Otter, pi. xxii, fig. 2 (Enhydra marina, Fleming). It is, however, quite probable that under 
the common name of Leopard Seal, several species of similar aspect are included by non - scientific 
observers.
