presents characters which are easily recognized. The Museum of 

 Paris jiossesses two skulls, from specimens taken at Nice by Risso 

 and Laurillard. There is another in the Museum of Marseilles, ob- 

 tained from one of a shoal which came ashore into Carry, Bouches 

 du Ehone, in 1862. — Gervais, Comptes Retidus, 28 Nov. 1864, 876 ;

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, tapering at the 

 tip, but subcylindrical at the base.

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



This lower jaw appears to differ from the lower jaw of 0. 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 measm-es as follows : —

Mr. Layard has sent me for examination a skull of a Grampus 

 taken from the shores of Table Bay, Cape of Good Hope, which is 

 contained in the South African Museum. It is a typical Grampus, 

 like G. Rissoanus, with four teeth on each side of the front of the 

 lower jaw. It chiefly diff'ers from G. Rissoanus in the shortness of 

 the triangle in front of the blowers, which is not continued over the 

 vomer. The lower jaw agrees so completely with the lower jaw of 

 G. Ricliardsonii, that I believe it belongs to this species, which was 

 probably received from the Cape. — See Gray, P. Z. S. 1865. 



The skull in the Cape Museum resembles in most particulars that 

 of Grampus Cuvieri, and may be considered that of a typical spe- 

 cies of the genus. It agrees with Beluga in the convexity of the 

 triangle in front of the blowers and in the general form ; but it 

 diifers from that genus in the elevation of the margins of the maxillae 

 over the orbits, and on the side of the hinder part of the beak in 

 front of the notch, showing that the genus is intermediate in form
