There has been imported from New Zealand a quantity of flnner- 

 fins, or baleen, which are all yellowish white ; this doubtless indicates 

 a diflferent species. 



The Finner Whales also inhabit the Columbian shores. Lewis 

 and Clarke mention the skeleton of a Borqual found near the 

 Columbia River, 105 feet long. — Travels, 422. 



Chamisso, in his accounts of the wooden models of whales which 

 were made by the Aleutians, of the species found in their seas, which 

 he deposited in the Berlin Museum, and described and figured in the 

 N. Acta Nat. Cur. xii. 212, figures three kinds of this genus : viz. 

 Abugulich, t. 16. f. 2 ; Mangidach, t. 16. f. 3 ; and Agamaehtschich, 

 1. 18. f. 4, the B. Agamachschilc, Pallas, Zool. Eosso-Asiat. i. t. a. 



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 genera — there is 

 a genus found at Kamtschatka which has not yet been described. 

 It is called Balcena TsehieJcagluk by PaUas (Zool. Eosso-Asiat. i. 289 ; 

 Nov. Act. Nat. Cur. xii. 259. 1. 19. f. 6). It has no dorsal fin, and a 

 smooth belly and chest ; the upper and lower part of the under 

 portion of the body are slightly keeled ; the head rounded, like Balce- 

 noptera, with the blower on the hinder part of the crown. The 

 lower side of the tail and the pectoral are white. 



6. CUVIERIUS. 



The rostrum of the skull very broad, continued as far as the 

 middle with very little diminution of width, and then rounded; 

 outer margin much more convex in the front half. Maxillary bones 

 broad as in Megaptera. The atlas with short, thick, rounded lateral 

 processes growing straight out of the upper half of the sides of the 

 body. The axis with two short broad lateral processes which do not 

 completely unite, having a regular oval basal aperture. The cervical 

 vertebrsB with oblong rounded bodies, with upper and lower lateral 

 processes which are not united into a ring. The neural canal trans- 

 versely oblong, flattened above. Vertebrae 64. Eibs 15 . 15 ; head 

 of first undivided ; the second and third each with a weU-developed 

 capitular process, which is longest and most slender in the third. 

 Sternum irregularly oval, notched in front. The scapula with a dis- 

 tinct acromion and coracoid. The humerus moderate. The radius 

 and ulna much longer than the humerus. Phalanges long. 



This genus is intermediate between Physalus and Sibbaldiws ; it 

 has the broad rostrum of the latter and the vertebrse and ribs of the 

 former, and a peculiar sternum.
