Orca ater, var. fusca. PI. xvii, fig. 3. 
A variety (?) of the above, with a lower falcate dorsal, with the belly, spots, and crescent of 
a yellowish cream color, instead of white and maroon, reported by Scammon from similar localities, 
may take the above varietal name until more material in regard to it is obtained. An Orca, under 
the name of Delphinus orca, is reported by Chamisso from the North Pacific and Kamchatka; very 
likely one of the above mentioned forms. 
Orca paoifica. 
O. capensis, Gray, 1868, p. 8, pi. 9. 
Ophysia pacifica, Gray, P. Z. S. 1870, p. 76; 1871, p. 93. 
Skull only, B. M. Reported by Gray to be probably from the South Pacific or Chile, but 
originally stated to be from the North Pacific. I can see no grounds for separating this from 
Orca, even subgenerically. 
Genus PhOCSena, Gray.

Bay Porpoise, of Scammon. 
San Francisco, California. 
Full material, skulls and skeleton, Mus. S. I. Figures and photographs from nature, and 
measurements. Eight blunt spines were noticed by me on the dorsal of a specimen of this species 
obtained in the harbor of San Francisco, February 8th, 1873. A dark line extended from the 
corner of the mouth to the pectorals. The belly was white, shading gradually into dark slate 
color on the back. The teeth in this species vary considerably in their shape, in some specimens 
being spade shaped, in others nearly tricusjrid, and in still others truncated scpuarely.
