I believe that the baleen or whalebone which is sold in the 

 market as South- Sea whalebone comes from this "NVhale. 



3. HUXTERUS. 



Ribs 15; the first double-headed, the rest single-headed. 

 Tympanic bones rhombic, nearly like those of Balana. Head 

 large, forming above one-fourth of the entire length of the adult.

Temminck and Schlegel, in the ' Fauna Japonica,' t. 28 & 29, 

 figure a AVhalc 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 Europe; sojthat we do not know 

 whether it is an Eubalana 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 Baktna Japonica in my monograph ; but Lacepede 

 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 Balana Sieboldii.
