North Seas of Europe. The differences which distinguish the variety from the common form, 
according to Captain Scammon, are as follow: The spout -holes are said to be higher, and a 
bunch, or hump, rises from the "small" of the back, about six feet forward of the flukes, extend- 
ing along the back two or three feet, and rising above it about six inches. They are also said to 
yield a larger proportion of baleen to the oil than the others. They have been frequently taken 
in the north-east gulf of the Ochotsk Sea. Before the variety can be confirmed, a more thorough 
knowledge of it is, of course, indispensable. Baleen of the normal form in B. M. and Mus. S. I. 
Summary. 
Out of forty-four species which appear to be more or less thoroughly characterized, ten are of 
unknown habitat. Leaving these out (with all species based on insufficient material), we have as 
the approximate distribution of the known Pacific Cetacea : Japan, five sjjecies ; northern seas, six 
species, including two or three which visit California ; warm seas and South Pacific, eleven species ; 
coast of western North America, from the Aleutian Islands to Central America, eighteen species, 
including several Aasitors from the Arctic Seas. The sj>ecies are as follow : 
JAPAN. NORTHERN SEAS. 
Delphinus longirostris ? Delphinapterus catodon. 
Neomeris phocsenoides. Orca rectipinna. 
Globiocephalus Sieboldii. Rhachianectes glaucus. 
Megaptera kuzira. Megaptera versabilis. 
Balsena Sieboldii? Balfenoptera velifera? 
Balaena mysticetus. 
WARM SEAS AND SOUTH PACIFIC. 
Clymenia alope. Lagenorhynchus albirostratus. 
C. obseura. Leucorhamphus Peronii. 
Tursiops catalania. Orca magellanica. 
Cephalorhynchus eutropia. O. destructor. 
Lagenorhynchus clanculus. O. pacifica. 
Physeter niacrocephalus. 
The absence of Phoccena, and of well-defined species of the Mysticeli, from the warm seas, is 
very marked, as is the paucity of Denliecli in the northern seas, while in the north European seas 
the latter are well represented. 
WEST COAST OF NORTH AMERICA. 
Delphinus Bairdii. Grampus Stearnsii. 
Tursiops Grillii. Kogia Floweri. 
Lagenorhynchus thicolea. Physeter macrocephalus. 
L. obliquidens. Bhachianectes glaucus. 
Leucorhanvphus borealis. Megaptera versabilis. 
Orca rectipinna. Balsenoptera velifera. 
O. ater. B. Davidsoni. 
Phocsena vomerina. Sibbaldius sulfureus. 
Globiocephalus Scammoni. Balsena Sieboldii. 
It is highly probable that to this list may be added two or three species of grampuses and 
dolphins, of which sufficient material has not yet been obtained for secure identification.
