N. with a ftrait, or very little arcuated flieli, with finooth 

 joints : Imaller at the pofterior extremity than at the 

 mouth: aperture a fmall j(}'^/^on» 



Yvom Sandzoich ; very rare. 



A fpecimen of this (hell, favoured us by Mr. Boys, was 

 a fmall matter arcuated, of an opaque-brown colour: 

 length about one tenth of an inch: the external part had 

 fcarce any appearance of its being concamerated, but one 

 fide being ground, eight or nine diftinft chambers appear- 

 ed. The (hell is very thick, and itrong for its fize : though 

 Mr. Walker fays, pellucid white. 



We have very little doubt this is the A^. Legianen of 

 Gmelin, although neither the fpecimen before us, nor 

 the figure given by Walker, has any appearance of be- 

 ing marginated.
