84°: CETACEA. 
This species loses its upper teeth at an early period and pre- 
serves only a few of its lower ones. The dorsal fin is lower and — 
further back than in D. Orca, Cuv. R. A. 1. 290. a 
M. F. Cuvier (Cetac. 193) has referred the Marsouin of Du- ~ 
hamel (Pech. iv. t. 9. f.5) to D. globiceps, but 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 D. melas. In both these points it suits better with this — 
species. . 
This species was first described from a skeleton and drawing — 
sent from Brest to Paris. The bad colouring of the drawimg in- — 
duced M. Cuvier to call it D. griseus, but it is black and not grey. — 
M. F. Cuvier regards it as distinct from D. aries of Risso, which — 
his brother thought was the same.— F. Cuv. Cetac. 184) . 
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 mches), 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. ‘a 
M. D’Orbigny says that this species has “‘ most affinity m the — 
external form to the Grampus of Hunter, t. 17, which Lacepéde 
called D. ventricosus, but differs essentially in the total absence — 
of teeth in the upper, and by the number in the lower jaw.” — 
Hunter does not figure any teeth in the upper and only a fewin 
the lower jaw. ria
