 Pennant have figured the infide of this (hell, with- 

 out paying any attention to the teeth. Dr. Lifter, 

 hmvevcr, thought their arrangement too curious to 

 be paffp- unnoticed. He has therefore engraved 

 them in his Hijl. Conchyliorum, and alfo in his Hijl.

The hinge of the Solen Sitiqua is furnifhed with three 

 teeth : two thick ones in one valve receiving a la- 

 mina between them from the other. An edged pro- 

 4u6tion from the teeth is continued down about the 

 third of an inch on each fide of the hinge, where it 

 terminates inwards in a rounded fhape. 



Da Cofta. in his Br. Conch, has defcribed the Solen Silt- 

 qua, but figured the S incurvatus of Dr. Solander. 

 Gmelin alfo has fallen into much the fame error, by 

 quoting Lifter, Hi/l. Conch, t. 413. A note of in- 

 terrogation, indeed, is very properly added, but no 

 reference is made to t. 409, f. 255, which is an exaft 

 copy of the true figure of the S' SHiqufl, in the HiJ.
