MAMMALIA. CETE. Narval. 355 



VII. C E T E. 



Have fpiracles * on the anterior part of the fkull; 

 • no feet, inftead of which they have pectoral fins, 



deftitute of nails ; and the tail is horizontally 



flattened. 



This order of Cete ought, from external fliape and habits of life, to have been arranged with the' 

 clafs of Fifhes •, but the illuftrious author having adopted the ingenious idea of employing the cir- 

 cumftance of fuckling their young as a charadteriftic mark for a number of animals, all of which 

 have warm red blood propelled by two auricles and two ventricles, found himfelf forced to include 

 thefe, which ought otherwife to have been named Cetaceous Fifties. They are not hitherto well 

 known, becaufe living only in the fea, they are difficultly made the fubject of obfervation ; even 

 thofe fpecies of Whales and Cachalots which have long been killed in vaft numbers annually, on ac- 

 count of the oil which they produce, are very imperfectly known to naturalifts. In general they 

 refemble fifhes in the form of their bodies ; all have peftoral fins, and a fin-like tail ; a fmall num- 

 ber of fpecies have a dorfal fin, but they are all deftitute both of the ventral and anal fins f . They 

 are found in almoft every part of the ocean, and the feas which communicate with it, though fome 

 fpecies are. more peculiarly confined to particular regions, and very few are found in the Red Sea.- 



XLV. NARVA L.— 44. M NOD N. 37. 



Has two very long, ftraight, and fpirally twifted teeth, which* 

 ftick out ltraight forwards from the upper jaw. The fpi- 

 racle, or breathing hole, is fituated on the anterior and up- 

 per part of the fkull.

* The word fpiracle is employed to denote a kind of pipe, or fiftulous opening, on the top of the head, 

 communicating with the nofe, through which the various fpecies blow large quantities of water with 

 great force, l-y the power of their breath, which likewife iflues from the fame openings, fo that they 

 may be confidered as noftnls not fituated on the nofe or muzzle. — T. 



\\ Thefe fins will be defcribed particularly in the clafs of Fifties.— T.. .
