 " 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 skuU of Delphinus 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 -Lf, larger and stronger ; skuU one-sixth the 

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



The short description of the B. Phoecenoides 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 Mua. 

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

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

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

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

 skuU 7, of nose 2|, width at notch 2| inches. 



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

 terized by the number of the teeth. 



tt Teeth of upper and lower Jaw conical, deciduous. Dorsal none.

 of the maxiUa bent down on the orbits, making the forehead very 

 convex ; lower jaw not so wide as the upper, with the condyle low
