THE DOLPHINS. 103 
GRAMPUSES. 
Of this group of the Delphinidce, which has been observed along the Pacific 
North American Coast, there is but little known ; they are commonly distinguished 
by the names given in the list of the dolphins found upon this coast. Our per- 
sonal knowledge of these obscure animals is so limited that we have hesitated 
whether or not to mention them ; but after due consideration we submit the fol- 
lowing remarks : 
SECTION IX.— THE WHITEHEADED OR MOTTLED GRAMPUS. 
Grampus Stearnsii, Dall. 
The average length of the Whiteheadcd or Mottled Grampus may be ten feet. 
Its muzzle terminates in a rounded point, and very nearly resembles that of the 
Phocana vomerbia. Its dorsal fin is narrow, quite high, and slightly falcated ; hence 
the animal is sometimes taken for the Orca ater, and its general appearance and 
movements through the water are very similar to those of that animal. Its indi- 
vidual marks vary more than any other species of the toothed whales of the coast. 
While the prevailing color is very dark, approaching to black, the head and anterior 
portion of the body — as far as the pectorals in some examples — are white, in 
others it is only partially so ; and frequently they are seen more or less mottled 
with light gray to the region of the dorsal fin. They are gregarious, and congre- 
gate frequently in large schools ; at other times two or three, or even a solitary 
individual, will be met with, wandering about the coast or up the bays in quest of 
food, which consists of fish and several varieties of crustaceans. It is rarely taken, 
as it is extremely wild and shy. 
SECTION X.— THE BOTTLENOSED GRAMPUS. 
The Bottlenosed Grampus is probably the largest of the Dolphin family of 
Cetaceans. Its color approaches nearer to brown than black. The fin on the back 
Ls comparatively small, angular in shape, with the longest side attached to the body, 
and placed much nearer the caudal fin than on other species of the same genus.
