CETACEA. 85 



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

 especially of the upper jaw. He gives the following measure- 

 ments : 



ft. in. 



Length, entire 9 



of head .... 1 6J 

 Height of dorsal.... 9 



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.

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

 M. D'Orbigny, and a second from Nice, brought by M. Lauril- 

 lard, which greatly resemble one another. 



3. GRAMPUS RICHARDSONII. 



Lower jaw straight, regularly diverging, scarcely bulging on 

 the side behind, united by a rather long, wide symphysis in 

 front ; obliquely truncated in front, with a rather prominent, 

 tuberous gonyx. Teeth 4-4, rather large, far apart, conical, ta- 

 pering at the tip, but sub cylindrical at the base.

a. Lower jaw. Presented by the Haslar Hospital Museum. 



This jaw appears to differ from the lower jaw of G. Cuvieri in 

 being much thicker at the symphysis, very obliquely 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. It measures as 

 follows :

Length, entire 16

Width at condyles 11 6
