"Knox now admits that this is not the Sulphur-botttom, which he 

 says is the Trigger of the New-Zealand whalers. He fancies that 

 B. marginata may be the true Finner of the south. I wUl try to 

 find some more of the bones." — Trans. New Zeal. Inst. 1870, 

 p. 26. 



This Whale, from the form and structure of the whalebone, can- 

 not be a Finner, but is certainly, as I arranged it, a true Right 

 Whale, very nearly allied to the Eight Whale of Q-reenland, and of 

 a very small size. The bones of this Whale would be a most valu- 

 able addition to the British Museum or any zoological museum. 

 They appear not to be uncommon in the Kawau Islands ; and the 

 measurements of the skull are a valuable addition to our knowledge 

 of the species. 



This small Right Whale of the Antarctic Sea is the representative 

 of the Eight Whale in the Arctic Sea, and, judging from the length 

 of the head, cannot be more than 14 or 15 feet long, while the 

 Greenland Whale is from 50 to 65 feet long. 



II. Baleen thicJc, not polished, with a thin enamel coat on each side, and a

 rounded at the end (Osteog. Get. t. 1. f. 19). Carpus cartilaginous, 

 with six carpal bones, a radius and cubitus, one radial and one cu- 

 bital and two carpals in the second range (Osteog. Get. t. 1. f. 1).
