Cuvier copies the figure of the head of this whale as that of the 

 Northern Rorqual, and points out its distinctions from that which 

 he had received from the Mediterranean. The nasal bones ap-

 noptera rostrata.

M. Ravin (Ann. Sci. Nat. n. s. xv. t. 9) figures the skull ; but 

 although it generally resembles Cuvier's figure above quoted, 

 it is shorter and broader in proportion, being only twice the 

 length of the width of the jaws in front of the orbit.

 and the tail 14 feet wide. He describes the skin as brown.
