Greenland Right Whale, and probably in all other Bcilcenidce , 
the female is the larger. The Japanese Whale (E. Siebaldii of 
Gray), according to that naturalist, “ is only described and figured 
from a model made in porcelain clay by a Japanese under the 
inspection of a Japanese whaler and of Dr. Siebold ; hut no 
remains of the animal were brought to Europe ; so that we do 
not know whether it is a Eubalcena or a Hanterius , or if it may not 
be an entirely new form.” Mr. Bennett observes that “ the Right 
Whale, so abundant and so little molested in the northernmost 
waters of the Pacific, especially off the north-west coast of America, 
is probably identical with the Greenland species ; ”* but Dr. Gray 
remarks that its baleen, which is very inferior in quality to that of 
B. mysticetus , “ shows that it is more allied to the Cape species, 
but apparently distinct from it.” Hunterius Temmwckii , Caperio 
antipodosum , and Madeayius australiensis, are three other Southern 
Whales, the distinctions of which are only beginning to be under- 
stood. In one or more of them a curious horny substance is 
commonly observed upon the fore part of the head, which the 
whalers denominate the creature’s “ bonnet.” One in the British 
Museum, obtained at the Sandwich Islands, is oblong in shape, eleven 
inches long and eight inches wide, with a very rough, pitted surface. 
The whole substance seems to be formed of irregular horny layers 
placed one over the other, the lowest layer being the last one 
formed ; and each of these layers is more or less crumpled and 
plicated on the surface, giving the irregular appearance to the 
mass. “ I do not recollect observing any account of this ‘ bonnet,’ ” 
writes Dr. Gray, “or giant corn, or rudimentary frontal horn, 
as it may be regarded, in any account of the Right Whale, nor 
in that of the Cachalot. I have especially searched for it in 
works by persons who have seen these whales alive, but without 
success. It has been suggested by Mr. Holdsworth, that the 
‘ bonnet ’ may be a natural development, and possibly charac- 
teristic of the species bearing it.” 
In the true Cetacea generally, or Cete of Dr. Gray, there are no 
hairs upon the skin, and the nearest approximation to bristles is 
generally supposed to be furnished by the baleen of the Mysticete ; 
but a South American genus of beaked Dolphin, Inia, has a well- 
bristled rostrum ; and in his description of the Greenland Right
