9. GRAMPTTS, 



297 



This species 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.—Ciiv. li. A. i. 290. 



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

 (Pech. iv. t. 9. f. 5) to D. fiJohiceps; but M. Duhamel particularly 

 observes that the pectoral and dorsal were nearly equidistant from 

 the head, and that the underside is paler than the back, golden 

 green, not white, which does not agree with D. melas. In both these 

 points it suits better with this species.

Skull of Grampus Cuvieri, Cuv. t. 22. f. 1. 



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 grey ; so that 

 the first specific name cannot be used, as giving a wrong impression 

 of the animal. M. F. Cuvier regards it as distinct from D. Aries of 

 Risso, which his brother thought was the same. {F. Cuv. Cetac. 184.) 



" The skull of the Brest specimen has the general characters of 

 D. Rissocinus ; the teeth are truncated ; the cervical vertebrae anchy- 

 losed ; and there are 12 dorsal vertebrte." — Gervais,Zool. et PaUont. 

 Franc, t. 37. f. 5. 



In D'Orbigny's specimens the dorsal was injured, and in two of 

 them nearly destroyed. The young, 7 feet long, had eight, conical, 

 acute teeth. The older, two males and one female, 10 feet long, 

 had only six or seven, blunt, carious teeth. The upper 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
