V. Elucidation respecting the Pinna ingens of 

 Pennant's " British Zoology." 



By Captain J. Laskey, M. W. S. 



(Read, nth June 1808. ) 



From the time when Mr Pennant first published his 

 "British Zoology," in 1777, a doubt has occurred 

 with regard to this shell, which, to the best of my 

 knowledge, has never been removed. Singular 

 good fortune having lately brought under my view, 

 the different shells described for Pinna ingens by 

 various authors, I am enabled to describe precisely 

 what Mr Pennant had so indefinitely stated, and 

 by that means, created those doubts under which 

 every writer on conchology has laboured since ; 

 and although the subject of this paper may appear 

 of little importance, I am still confident the eluci- 

 dation of any doubtful point in Natural History, 

 will meet with due attention from this Society.
