OEDEE OF CETACEA. 89 



Greenland Right Whale, and probably in all other Ba/cenkhe, 

 the female is the larger. The Japanese Whale (E. SiehakUl, 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 ; but no 

 remains of the animal were brought to Europe ; so that we do 

 not know whether it is a Euhalmia or a Hitnfenus, 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 

 S. mysticetus, " shows that it is more allied to the Cape species, 

 but apparently distinct from it." Hunterius TcmmiucJdi, Caperia 

 (intipodosum, and Macleai/ius ausfraliensis, 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 irregidar 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 irregidar apioearance 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 accormt of the Right ^^^lale, 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 Cetacca 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 Mijsticde ; 

 but a South American genus of beaked Dolphin, Inia, has a well- 

 bristled rostrum ; and in his description of the Greenland Right
