notices a Dolphin without any dorsal, an d with rounded
teeth in the lower jaw only, under the name o f Epiodon

I t loses its u pper teeth a t an early period and preserves
only a few o f 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 [Pech. iv. t. 9, / 5) to D. Globiceps, aud M.
Duhamel particularly observes th a t th e pectoral and dorsal
vyere nearly equidistant from the head, and th a t th e under
side is p ale r th an the back, golden green, not white,
which does not agree with Melas. I t agrees in both these
points better with this species.
This species was first described from a skeleton and
drawing sent from B rest to Paris. The bad colouring of
the drawing induced M. Cuvier to call it D. griseus, b u t it
IS black and not gray. M. F . Cuvier regards it as distinct
from D. aries o f R isso, which liis brother thought was the
same. F. Cuv. Cetac. 184.
The young, 7 ft, long, h ad eight conical, acute teeth.
The older, two male and one female, 10 ft. long, had only
SIX or seven blunt, carious — D 'Orbigny. T h e up-
p er jaw longest (4 inclies), without any indication of
teeth, even in the young one, b u t witb a slight groove for
the reception of th e edge of the lower jaw. M. D ’Orbigny
says th at this species has “ most affinity in th e external
form to the Grampus o f Hu n ter, t. 17, which Lacepède
called D. ventricosus, b u t differs essentially in th e total ab sence
o f teeth in the upper, and by the number in the lowe
r jaw.” H u n te r does not figure any teeth in th e upper
and only a few in the lower jaw. I n D ’Orbigny’s specimens
the dorsal was injured, and in two o f them nearly
destroyed.

Lesson refers this species to the genus Globiocephalus,
b u t the position o f the dorsal and the form o f th e pectoral,
as well as the description o f the teeth, make me believe it
rather belongs to this genus. M. Cuvier observes th a t his
D. griseus is only described from a b ad drawing of this
species, but M, F. Cuvier, who had a new description, and
M. Laurillard, consider them as distinct. Reg. Anim. i.
