30 CETACEA. 



gives the following particulars, except what appears to be common 

 to the genus. He says, " it has a boss on the occiput, and its 

 dorsal is nearly over the pectoral ;" in the European and Bermu- 

 dean figures it is over the end of these fins. 



Cuvier's figures of the adult skull differ from Rudolphi's figure 

 of M. lonaimana, in the intermaxillaries being narrower and con- 

 tracted in front of the blowers, and then rather widened again and 

 linear, and the temporal bone is broader and more triangular; 

 which makes me believe it is a distinct species. 



M. Desmoulin, in describing this species, pointed out the two 

 most important characters of the genus, viz. the length of the 

 pectoral, and their only having four fingers.

Dorsal small, and behind the middle of the back ; the pectoral 

 fin rather short, and less than % the entire length of the body ; 

 nose and side of the throat have round warts ; belly plaited.

The figure in the * Fauna Japonica ' is from a drawing brought 

 home by M. Siebold, not accompanied by remains. M. Siebold 

 observes that the Japanese distinguish three varieties : 



1. Sato Kuzira. Black, nose more elongate and rounded, and 

 the pectoral long ; the belly and lower face of the pectoral are 

 grey, with white rays. 



2. Nagasu Kuzira. Paler, nose more pointed, the belly has 

 10 plaits. In both, the lower jaw is larger than the upper. 



3. Noso Kuzira. Distinguished from the first because the 

 back and fins are white-spotted. Faun. Jap. 24. 



Forster, in Cook's Voyage, appears to have met with a species 

 of this genus between Terra del Fuego and Stratten Island. He 

 says, " These huge animals lay on their backs, and with their long 

 pectoral fins beat the surface of the sea, which caused a great 

 noise, equal to the explosion of a swivel." 



Lesson (Tab. Reg. Anim. 202) gives the name of B. leucopte- 

 ron to " the Hump-back of the whalers in the high southern 

 latitudes."

Chamisso figures a species of this genus from the Aleutian seas, 

 under the name of Aliomoch or Aliama, when young, Aliamaga
