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. longimana, in the intermaxillaries hemg narrower and con 
tracted in front of the blowers, and then rather widened again and 
linear, and the temporal bone is broader and more trisngaey 
which makes me believe it is a distinct species. 
M. Desmoulin, in describmg this species, pomted out the twa 
most important characters of the genus, viz. the length of the’ 
pectoral, and their only having four fingers. py

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 m the high southern” 
latitudes.” . 
Mitchell (Travels Australia, ii. 241) speaks of a Hunch-backed 
Whale which inhabits Portland Bay, Australia Felix. 
Chamisso figures a species of this genus from the Aleutian seas, 
under the name of Aliomoch or Aliama, when young, Aliamaga”
