" Knox now admits that tbis 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 will 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 Bight 

 Whale, very nearly allied to the Bight Whale of Greenland, and of 

 a very smaU 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 Bight Whale of the Antarctic Sea is the representative 

 of the Bight 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 thick, not polished, with a thin enamel coat on each side, and a 

 coarse thick fringe (cf. p. 37).

First rib broad at the vertebral end. Tympanic bone square; 

 aperture nearly as long as the bone. The first six cervical ver- 

 tebra? aU united by their bodies. The upper lateral process of the 

 atlas subcylindrical, narrow at the base, recurved and rounded at the 

 end ; the lower lateral process narrow at the base, swollen and 

 rounded at the end (Osteog. Cet. 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. Cet. t. 1. f. 1). 

 Scapula as long as broad, with a small cylindrical coracoid process, 

 rounded at the end. Five phalanges to the middle finger, four to 

 the index and ring fingers, four to the little finger, and two to the 

 thumb. The first rib is simple at the upper and thin at the free 

 edge. The nasal bone rhomboidal, moderate. Vertebra? 50-59.
