 Teeth only in front.

 vex ; teeth of upper jaw deciduous, of lower jaw only in front over 

 the short symphysis. The dorsal fin low; the skull depressed;

i. Grampus. 



I. Grampus Cuvieri (the Grampus). Murie, Journ. of Anat. 

 and Phys. 1870, vol. v. tab. v. Flower, Trans. Zool. Soc— 

 Inhabits Mediterranean, Bay of Biscay. Isle of Wight, 1845; 

 Bury (skull in Brit. Mus.) Coast of Cornwall. The French 

 naturalists have made two species, Delphinus griseus and D. Risso- 

 anus, and Gervais, in his ' Osteographie,' figures the skeletons of 

 both kinds. Mr. Flower, who examined an adult female 11 feet 

 long, thinks they are the same. The differences between them are 

 not great; the two specimens figured may belong to the sexes. 

 It appears to be one of those species which inhabits the Mediter- 

 ranean and the Bay of Biscay, and only comes north as far as the 

 south of Britain incidentally, along with the mackerel. — Proc.
