The other species (The Balenoptera 

 Lacep.) have a fin on the back. They are again 

 subdivided according to whether the gills be 

 smooth or wrinkled. 



The Balenopteka with smooth belli/, 



Approach very nearly to the proper whales : only 

 one species is well known, named 



Gibbar, by the Basques (Balcena Physalus, L.) Finn- 

 Fisch of the Dutch, &c, {Lacep. I. f. n.) 



As long, but much more slender than the Com- 

 mon Whale : very common in the same haunts, 

 but avoided by fishers, as it yields but little oil, 

 and is extremely ferocious. It is difficult to 

 catch, and even dangerous for small vessels, by 

 the violence of its movements. 



The Balenoptera with wrinkled belly, 



Have the skin of the under part of the throat and 

 chest folded longitudinally in very deep wrinkles, 

 and susceptible of great dilatation. Their use in the 

 economy of the animal is not known. 



One species only is well determined. 



The Jubarta of the Basques, (Bal. Boops., L.) Lacep. I. f. 

 in., IV. f. i & ii., V. f. i., et VIII. i & ii. 



Is said to approach to the length of the Com- 

 mon Whale, but has all the dangerous quali- 

 ties, tire, of the Gibbar. 



These Whales have been taken in the Medi- 

 terranean as well as in the Ocean.
