THIS elegant whale belongs to the genus Aodon, 

 which is characterized by having no baleen and no 

 teeth. It is the only known species of the genus, 

 and is with much hesitation, and we think errone- 

 ously, by Fred. Cuvier and Blainville, made to 

 correspond with the dolphin of Dale, which appears 

 to be identical with the genus last discussed. 



The specimen of the animal now before us was 

 stranded in 1825, near Havre; was examined by 



* Though we believe this to be a complete misnomer, yet 

 we retain it, because under this name the species has been 

 satisfactorily described by Blainville and Lesson.
