bones rhombic, nearly like those of Balena. Head large; of 
adult, about one-fourth the entire length. Vertebre 52. 
E, australis, Gray, Proc. Zool. Soc. 1864. 
Balena australis, Cuvier, Oss. Foss. t. 25. f. 1, 2 (young), f. 5, 6 (adult). 
Hab. South Sea, Cape of Good Hope. Two skeletons, Mus.

I believe that the baleen or whalebone which is sold in the 
market as South-Sea whalebone comes from this Whale. 
3. HuNnTERUS. 
Ribs 15; the first double-headed, the rest single-headed. 
Tympanic bones rhombic, nearly like those of Balena. Head 
large, forming above one-fourth of the entire length of the adult. 
Hunterus Temminckit. 
Balena mysticetus australis, Schlegel, Abhandl. 37. 
Hab. South Sea, Cape of Good Hope (Horstock). Skeleton 
of young, Mus. Leyden. 
Temminck and Schlegel, in the ‘ Fauna Japonica,’ t. 28 & 29, 
figure a Whale from Japan (from a model made in porcelain-clay 
by a Japanese) under the name of B. australis; but no remains 
of it have been as yet sent to Hurope; so that we do not know 
whether it is an Hubalena or a Hunterus, or if it may not be an 
entirely new form. The baleen sold in the market as “ North- 
west-coast whalebone,” which I figured in the ‘ Zoology of the 
Erebus and Terror,’ t. 1. f. 4, is quite distinct, and fetches a 
different price, from that called “ South-Sea whalebone,” which 
is said sometimes to be brought from the Cape—showing that 
the Whalebone-Whale of the North Pacific is a distinct species. 
I called it Balena Japonica in my monograph; but Lacépéde 
had already given that name to a Whale described from a Japanese 
drawing, which is differently coloured from the one figured by 
Temminck: therefore I now propose to call it Balena Sieboldit.
