Inhab. Falkland Islands, Quoy. 
Desmoulin (Dict. Class. H. Nat.i.164), under the name of Be 
lena rostrata australis, described a whale seen by M. Quoy © 
the shores of Falkland Islands, which he says was exactly lil 
B. Physalus. It was 55 feet long, and the pectoral fin 6 fee 
3 inches, that is, about 3 the entire length, the same as in Bale 
noptera Physalus ; but he says the dorsal fin was over the m i 
organ, a character which as far as I know is peculiar to the Hum: 
backed Whale (Megaptera), thus presenting a combination of cha 
racters, which, if correct, will not only prove it to be a distine 
species, but one forming a section by itself. | 
Lesson (Tab. Reg. Anim. 1.202) gives the name of Balenoptert 
australis to the “‘ Fin-back of the Whalers of the South Sea.” I 
is most probably intended for this species, as Falkland Islands i 
given for the habitat; but it may be Megapteron Poeskop, or per 
haps a confusion of both. 
If reliance is to be placed on the wooden models made by the 
Aleutians, which have been described and figured by Chamisso 
and many of them are not bad representations of known gene 
there is a genus found at Kamtschatka which has not yet been de: 
scribed. It is called Balena Tschiekagluk by Pallas, Zool. Ross 
Asiat.i.289; Nov. Act. Nat. Cur. 259. t.19.f.6. It has no dor- 
sal fin, and a smooth belly and chest; the upper and lower par 
of the under portion of the body is slightly keeled, the hea¢ 
rounded, like Balenoptera, with the blower on the hinder part | 
the crown. The lower side of the tail and the pectoral are white.
