M. Quoy's description and figure, on which F. Cuvier 

 founded I), haslatus, was from the specimen originally 

 described by me, and now transferred from the College of 

 Surgeons to the British Museum. 



This species has some character intermediate between 

 Phoc(vna and Delphinus.

M. Garnot's description, as given by F. Cuvier, is veiy 

 short, but it appears to fit this species. The D. a museau 

 court of the Voy. a Pole Sud is said to have 4^ teeth. It 

 is evidently this species as determined by the examination 

 of the skull at Paris, and there is a skull named D. hivitta- 

 lus, D'Orbigny, 1830. Beak quite flat above; triangle 

 to near the middle of the beak ; which appears to be 

 only a variety of this species. 



Length of skull .... 14'0 inches and lines. 



,, beak .... 7-0 



Width at notch .... 4.1 



The skull, Dauphin d museau court, in the Paris Mu- 

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

 tooth-line ; nasal gi-ooves wide in front.

The skull of this species is intermediate in form between 

 the Lagenorhynchus and Delphinus.
