170 AI/\ William Wood's Obfervatlons on the 



fmootb, and without teeth. This his figure con- 

 traditls, as well as two fpecimens in my cabinet, the 

 teeth of which meet in the centre, though their 

 fize is very much reduced. The drawing which 

 I have given is from one of them.

The beautiful arrangement of teeth in the hinge of 

 this fliell is not to be equalled by any other fpecies 

 on our fliores. The regularity of their order and 

 the elegance of their form make an accurate 

 figure particularly defirable. This I have attempt- 

 ed to give, to the beft of my abilities, in a magni- 

 fied reprefentation. 



The hinge is to be feen in all its beauty only in live 

 fhells. 



Of the remaining genera little need be faid, as the hinges are, for 

 the moft part, without teeth. I have, therefore, only figured one 

 fpecies of each genus, which, I prefume, will be thought fufficient.
