Heterodon Dalei (Lesson) is not from Dale’s description of 
this whale, but from Blainville’s account of Delphinorigaea 
micropterus. 4 
Lacepéde placed this species as the type of hii Hyperoodon ‘ 
‘and refers Delphinus bidentatus to Delphinus ! 
F. Cuvier considers Hunter’s and Baussard’s as incontestably 
the same species, taking no notice of the position of the dorsal 
(Cetac. 242). Dale does not mention the teeth, but they are 
only to be seen when the flesh is removed. 
** Dorsal fin behind the middle of the back, triangular. 4
