The short description of the D. Phocenoides of Cuvier, which — 1 
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. Phocenoides, brought from Malabar — 
by Dussumier in 1837.” It is broader and shorter than that of ~ 
Phocena communis; teeth spathulate, rounded, oblique, 335 — 
palatine bones and intermaxillaries broad, as seen in the roof of — 
the beak. age of this skull 7, of nose 23, width at notch 2 
inches. AM 
The skulls are much alike, but they may be two species cha~ 
racterized by the number of the teeth. :
