Habitat. . The great freshness of a head in pos- 

 session of Mr. Sowerby induces M. de Blainville to think 

 the species European.

 frontal convexity more abrupt ; beak more defined ; teeth 

 twenty-one, twenty-two, or twenty-three on each side; seven

Note. Of this Sub-genus Delphinus Bonji, D. Linensh, D. Daliiis, 

 D. Orca, D. FereSy D. Canadensis, D. Bsrtini, being' all marked as doubt- 

 ful by M. Desmarest, and so considered by the Baron, we forbear to in- 

 sert them. The same may be said of M. Rafinesque Smaltz"s Sub-genus 

 OxYPTERus, characterized by two dorsal fins, and of which the onlv 

 species is D. Mongitori, observed but once, and having no description or 

 figure. Should the above character be correct, this animal must be 

 distinguished not only from the Dolphins, but from all the other Cetacea. 



Sub-genus II. — Phoc^na (Marsouin.) No beak ; muzzle 

 short and convex ; numerous teeth in each jaw ; dorsal Jin. 



909. 1. D. PAoc^eTifl (Dolphin Marsouin.) Body and tail 

 elongated; muzzle rounded; teeth compressed, trenchant ; 

 twenty-two to twenty-five in each side of two jaws ; dorsal 

 fin about the middle of the back, almost triangular and 

 rectilinear ; colour blackish above and white below ; total 

 length four or five feet.
