 " Cape of Good Hope," and " Malabar" (Dussumier). 



The figure in the ' Fauna Japonica ' is from a drawing made by a 

 Japanese artist under Burger's inspection. 



The skull of Deljihinus melas in the Leyden Museum is more 

 swollen and broader than that of Phoccena communis ; the nose is 

 shorter, broader, more rounded at the end, and nearly flat, not 

 shelving above ; teeth \^, larger and stronger ; skull one-sixth the 

 entire length (in Plioccena one-fifth). Nameno-juo, Japan. 



The short description of the D. PJioccenoides of Cuvier, which 

 Dussumier is said to have discovered at the " Cape of Good Hope," 

 agrees with the figure in the ' Fauna Japonica.' A skull in Mus. 

 Paris, marked " D. Phoccenoides, brought from Malabar by Dussumier 

 in 1837," is broader and shorter than that of Phoccena commtmis; 

 teeth spatulate, rounded, oblique, ^^ ; palatine bones and inter- 

 maxillaries broad, as seen in the roof of the beak. Length of this 

 skull 7, of nose 2|, width at notch 2^ inches. 



The skulls are much alike, but they may be two species charac- 

 terized by the mimber of the teeth. 



tt Teeth of upper and loxoerjato conical, deciduous. Dorsal none.
