The skull of this species is intermediate in form between the 

 Lagenorhynchus and Delphinus. 



M. Garnot's description of D. bivittatus, as given by F. Cuvier, 

 is very short, but it appears to fit this species. 



The skull, marked Dauphin a museau court, in the Paris Mu- 

 seum, has teeth f f ; triangle extends much in front of the tooth- 

 line ; nasal grooves wide in front ; length, 14J ; beak, 8 ; width 

 at notch, 3J inches. It is evidently this species. 



There is a skull named D. bivi$fatus, D'Orbigny, 1830, in the 

 Paris Museum, beak quite flat 'above; triangle to near the 

 middle of the beak; length of skull, 14; of beak, 7; width at 

 notch, 4 inches, which appears to be only a variety of this spe- 

 cies. 



This is probably the skull of the specimen and skull figured 

 as D. cruciger, If Orb. Voy. Amer. Merid. Mam. t. 21, which is 

 represented as black, the underside from back of chin, and streak 

 on upper part of the side from the eyes to the base of the tail 

 white. Teeth ?
