external form to the Grampua of Hunter, t. 17, which Lacepede 

 called D. ventrlcosus, but diflers essentially in the total absence of 

 teeth in the ujipor, and bj^ the number in the lower jaw." Hunter 

 does not figure any teeth in the ujiper, and only a few in the 

 lower jaw.

M. Laurillard observes, the teeth are conical, early deciduous, espe- 

 cially of the upper jaw. He gives the following measurements : —

Length, entire 9 



Length of head 1 6^ 



Height of dorsal 9 



Lesson refers this species to the genus GloLiocephalus ; 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 B. griscus is only described from 

 a bad drawing of this species ; but M. F. Cuvier, who had a new 

 description, and M. Laurillard, consider them distinct. — Reg. Anim.

In the Paris Museum there is a skull from EocheUe, sent by 

 M. d'Orbigny, and a second from Nice, brought by M. LauriUard, 

 which greatly resemble one another. 



Gervais observes, " The maxillaries arc visible below. The frontal 

 region is rather flattened. Cervical vertebrsE soldered together; 

 dorsal 12, lumbar 7, caudal 49 = 68. The chevron bones commence 

 at the forty-fifth of the series. Inhab. Nice. Length about 10 feet 

 (3 metres)." 



G. Cuvier described Grampus Rissoanus, which is very nearly 

 allied to his D. griseus ; but the former lives in the Mediterranean, 

 and the latter on the coast of Brittany. The cranium of this species
