the Squalus Cornubicus of Gmelin. 83 



me to be fo very particular in my account of this fpecies. If I am 

 wrong in fuppofing it the Porbeagle of Mr. Pennant, I can anfwer 

 for the exa&nefs of the description. It cannot be the Beaumaris 

 Sharks becaufe Mr. Davies (upon whofe confummate accuracy any 

 one may implicitly rely) defcribes it with a blunt nofe ; this has a 

 fharp one. Upon what authority Gmelin joins the Porbeagle and 

 Beaumaris (harks as one fpecies, I do not pretend to know. Per- 

 haps it would be advifable that thofe who have opportunities 

 fhould examine them very minutely. Gmelin defcribes it as having 

 a fold or plait (p/ica) on each fide of the tail. In the prefent fpe- 

 cies there was a ftrong elevated line or ridge, but nothing of a plait. 



From the rows of the teeth, the fifliermen who caught it judged 

 it to be two years old. My friend Mr. Whitear told me, that he 

 has feen them eight feet long, with a triple row of teeth. 



There was nothing in the ftomach. 



The eflential character of this fpecies may be expreflfed as fol- 

 lows : 



S. corpore tereti aniice acuto caudam verfus deprejfo et utrinque angu- 

 lato.
