 $ Dolph. p. 7. 



Beak of the skull only rather longer than the brain-case. Skull 

 depressed, thick, with the sides rather bent down behind the notch. 

 The beak depressed, broad, rounded on the sides, rather longer than 

 the length of the brain-case ; the intermaxillaries flat, rather broad. 

 Teeth small, slender, five or six in an inch. 



The skull bears a considerable affinity to the skulls of Phoccewi, 

 Neomeris, Beluga, and Monodon in the bending down of the sides.

The D. cephalorhynckus of F. Cuvier, judging from the figure of 

 the skull given by Schlegel, appears also to belong to this genus.
