The skull of this species is intermediate in form between the 

 Ldijcnorhynchus and Delplunus. 



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

 very short, but it ai)pears to fit this species. 



The skull, marked Dauphin a museau court, in the Paris Museum, 

 has teeth _|^ ; 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 species. 



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

 Museum (beak (juite 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 species. 



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

 D. cruc'iger (D'Orbigny, Voy. Amcr. Mcrid. Mamm. 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 ? 



The Delph'uw^ ohscurus, var. (Quoy & Gaim. Voj'. Astrol. i. 151. 

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

 belonging to the Museum of Cape Town. He prepared the specimen 

 I described ; indeed it is probably the same example. 



Phocreua australis, J. Peale, U. S. Expl. Expcd. 33. t. G. f. 2. 



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

 white lateral line commences opposite the jjosterior edge of the dorsal 

 fin, and reaches the tail ; beneath M'hite, which joins the grey of the 

 side by an undulated line. Teeth |-^-|-^=120. Length 84, pec- 

 toral fin 10 inches. 



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

 same species.
