It loses its upper teeth at an early period and preserves 

 only a few of its lower ones. The dorsal fin is lower and 

 further back than in D. orca, Cuv. R, A. 



M. F. Cuvier {Cetac. 193) has referred the Marsouin of 

 Duhamel [Peek. iv. t. 9, /. 5) to D. Globiceps, and M. 

 Duhamel particularly observes that the pectoral and dorsal 

 were nearly equidistant from the head, and that the under 

 side is paler than the back, golden green, not white, 

 which does not agree with Melas. It agrees in both these 

 points better with this species. 



This species was first described from a skeleton and 

 drawing sent from Brest to Paris. The bad colouring of 

 the drawing induced M. Cuvier to call it D. griseus, but it 

 is black and not gray. M. F. Cuvier regards it as distinct 

 from D. aries of ilisso, which his brother thought was the 

 same. F. Cuv. Cetac. 184. 



The young, 7 ft. long, had eight conical, acute teeth. 

 The older, two male and one female, 10 ft. long, had only 

 six or seven blunt, carious teeth. — D^Orbignij. The up- 

 per jaw longest (4 inches), without any indication of 

 teeth, even in the young one, but with a slight groove for 

 the reception of the edge of the lower jaw. M. D'Orbigny 

 says that this species has " most affinity in the external 



form to the Grampus of Hunter, t. 17, which Lacepedc 

 called D. ventricosus, but differs essentially in the total ab- 

 sence of teeth in the upper, and by the number in the low- 

 er jaw." Hunter does uot figure any teeth in the upper 

 and only a few in the lower jaw. In D'Orbigny's speci- 

 mens the dorsal was injured, and in two of them nearly 

 destroyed.

Lesson refers this species to the genus Globiocephalus, 

 but the position of the dorsal and the form of the pectoral, 

 as well as the description of the teeth, make me believe it 

 rather belongs to this genus. M. Cuvier observes that his 

 D. griseus is only described from a bad drawing of this 

 species, but M. F. Cuvier, who had a new description, and 

 M. Laurillard, consider them as distinct. Reg. Anim. i.

Grampus ? 



Lower jaw straight, regularly diverging, scarcely bulg- 

 ing on the side behind, united by a rather long, wide sym- 

 physis in front. Obliquely truncated in front, with a ra- 

 ther prominent, tuberous gonyx. Teeth 4-4, rather large, 

 far apart, conical, tapering at the tip, but subcylindrical 

 at the base.

This jaw appears to differ from the lower jaw of G. Cu- 

 vieri in being much thicker at the symphysis, very ob- 

 liquely truncated in front, and rather projecting below. 

 Teeth 4-4, large, conical, rather acute and recurved ; the 

 upper edge behind the teeth round, with many minute 

 holes on the edge.
