*JC THE ROUND HEADED CACHALOT. 



this opening, which nature, as we have already feen, has 

 deftined for a different purpcfe. 



This fpecies is far inferior in fize, to that above de- 

 fcribed ; the largeft of that great number juft mentioned 

 did not exceed twenty-four feet in length. Its head is 

 round, and the fhape of the teeth the reverfe of thofe of 

 the blunt headed kind. They are fmaller at the back, 

 than at the top, where they are quite fiat, marked witli 

 concentric lines. Tlieir bottom is pierced with a fmali 

 orifice, bearing no rcfemblance to the large cavity, de- 

 fcribed in the former fpecies. The back fin is wanting j 

 inftead of it is a rough knotty kind of fpace *.
