c. Stuffed skin. Cape of Good Hope. Presented by the Council of

Skull : Length, entire 15 



Length of nose 8 



Length of lower jaw 12 



Width at orbits 6 6 



Width at notch 3 9 



Width at middle of beak 3 



Body : Length, entire 5 1 



Length to dorsal fin 2 1 



Width of tail 1 2 



The skull of this species is intermediate in form between the 

 LoAjenorhijnclius and Delpliinus. . 



M. Garnot's description of D. hivittatus, 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 Museum, 

 has teeth f^ ; triangle extends much in front of the tooth-line ; nasal 

 grooves wide in front ; length 14|, beak 8, width at notch 3| inches. 

 It is evidently this sjiecies. 



There is a skull, named D. hivittatus, D'Orbigny, 1830, in the Paris 

 Museum (beak quite flat above ; triangle to near the middle of the 

 beak ; length of skidl 14, of beak 7, width at notch 4 inches), which 

 appears to be only a variety of this species. 



This is probably the skuU of the specimen and skull figured as 

 D. cruciger (D'Orbigny, Voy. Amer. Merid. Mamm. t. 21), which is 

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

 iipper part of the side from the eyes to the base of the tail white. 

 Teeth ? 



The DeJphinus ohscurus, var. (Quoy & Gaim. Voy. Astrol. i. 151. 

 t. 28) is described from a specimen prepared by M. Jules Verreaux, 

 belonging to the Museum of Cape To"mi. He prepared the specimen 

 I described ; indeed it is probably the same example. 



Pliocfena australis, J. Peale, U. S. Expl. Exped. 33. t. 6. f. 2. 



Snout black ; fins (all) dark slate-colour ; sides paler or grey ; a 

 white lateral line commences opposite the posterior edge of the dorsal 

 iin, and reaches the tail ; beneath white, which joins the grey of the 

 side by an undulated line. Teeth |-J-f^=1^0, Length 84, pec- 

 toral fin 16 inches. 



Inhab. South Atlantic Ocean ; coast of Patagonia. Is perhaps the 

 same species.
