Catodon albicans, Lacep. 



White ; young black ; the nose of the skull nearly j the 

 entire length, U the length of its width at the anterior 

 notch ; teeth |-|.

Skull in B. M. from Greenland, length entire 20-0, of 

 beak 9-6, width at notch 6," at orbit I'.S. 



Mr. Barnston informs me the Beluga is called Keela 

 hiak by the Esquimaux. In the St. Lawrence they rarely 

 exceed 15 feet long. The male specimen he procured for 

 the British Museum was 12^ feet long, 6 feet 8 inches in 

 circumference at the thickest part.

 tremitatibus nigricantibus, Commerson MSS. D. Com- 

 mersonii, Lacep. 317, from Cape Horn, cited by Cuv. R. 

 A. i. 291, and Oss. Foss. v. 289. 



According to Desmarest {Mam. 521), Raffinesque 

 notices a Dolphin without any dorsal, and with rounded 

 teeth in the lower jaw only, under the name of Epiodoti 

 Urganantus (Desmarest calls it Delph. Epiodon), from 

 Sicily. 



*** Teetli in both jaws permanent, compressed. 

 Neomeris, Gray. 

 Teeth numerous, compressed, nicked, acute, extending 

 nearly the whole length of the jaw ; dorsal fin none ; nose 

 of skull short, rounded at the end, flat, shelving above.

The figure in the ' Fauna Japanensis ' is from a drawing 

 made by a Japanese artist luider Burger's insjjection. 



The skull in the Leyden museum is more swollen and 

 broader than that of Phoccena ; the nose is shorter, broad- 

 er, more rounded at the end and nearly flat, not shelving 

 above ; teeth \^, larger and stronger ; skull ^ the entire 

 length, (in Phocaena \). Nameno-juo, Japan. 



The short description of the D. PhocoBnoides of Cuvier, 

 which Dussumier discovered at the " Cape of Good 

 Hope," agrees with this species. There is in Mus. Paris, 

 a skull of " D. Phocwnoides " brought from Malabar by 

 Dussumier, in 1837. It is broader and shorter than Pho- 

 ccena communis; teeth spathulate, rounded, oblique, ff; 



palatines, bones and intermaxillaries broad, as seen in the 

 roof of the beak.
