OBSERVATIONS. 



There may frequently be observed some very minute 

 and fine longitudinal white lines, from which circumstance 

 it has been often mistaken for T. striata; but the lateral 

 teeth will at all times distinguish it, there being two small 

 lateral teeth in one of the valves only. We believe that 

 the T. halaustlna and T. planata of Linnneus are among 

 the numerous varieties of this species. — [Turton.) 



I have copied the above from Turton's " Bivalves of 

 the British Islands," believing our shell to be the tenuis 

 of authors. Mr. Say, unfortunately, has left no descrip- 

 tion of this species, which was sent to him by Professor 

 Ravenel of Charleston, who found it on the shore of Sul- 

 livan's Island. — Ed.
