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 EschricMius 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 Shumagin Islands, Alaska; and some 

 remains of cervical vertebrse 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 Megaptera. 



The following Cetacea, mentioned by Captain Scammon, are not at the date of this paper 

 represented by material sufficient to indicate their zoological position : 



Grampus, Panama. Grampus, San Diego Bay. 



Grampus, Puget Sound. Scrag Right Whale, northern seas. 



Grampus, Bottlenosed. 



The other marine mammals mentioned, are the Walrus {Rosmarus ohesus, Illiger); the Leopard 

 Seal, pi. sxii, fig. 1 {Phoca Peal'd? Gill); the Banded Seal, pi. xxi, fig. 2 {Histriophoca 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 angusiirostris, Gill); and the 

 Sea Otter, pi. xxii, fig. 2 [Enhydra marina, Fleming). It is, however, cpiite probable that under 

 the common name of Leopard Seal, several species of similar aspect are included by non- scientific 

 observers. 



San Feancisco, Califobnia, March, 1873. 



Note. — To Mr. Ball's Catalogue may be added the Squarehcaded Grampus and Brownsided Dolpbin of Sauta Barbara Channel.— C. M. S.
