THE ORDER CETACEA.

Dr. Klein has distinguished two varieties of this species, 

 one he paradoxically names the " Southern Nord Caper," 

 the back of which is very flat ; and the other, whose back 

 is more convex, he has given it the cognomen of the 

 " Western Nord Caper," numbers of which I had op- 

 portunities of seeing. 



The water ejected by this species is thrown out in 

 the form of radii, and not in that of a jet d'eau, as is 

 the case with the other whales, a fact with which the 

 reader no doubt is familiar. 



The varieties just mentioned, yet remain to be proved 

 whether they are distinct, or whether they are mere 

 sexual characters, or marks of age, or arising from un- 

 known causes. 



This species of the Cetacea inhabits the Northern part 

 of the Atlantic Ocean, situated between Spitzbergen, 

 Norway, and Iceland. It also is a resident of the Green- 

 land and Arctic Seas, where Mr. Backstrom made a 

 drawing of one in 1779, and presented it to the late 

 Sir Joseph Banks, P.R.S. It has also been met with in 

 the Japan Seas, consequently in the Great Boreal Ocean 

 in the 40th degree of latitude.
