13 Mr. Cuming informs me that he has 

 forwarded no less than six distinct Uni- 

 ones from Ceylon to Isaac Lea, of Phila- 

 delphia, lor determination or description. 



14 M. smaragdinus, Chemn. 



15 As Avicula. 



16 The specimens are not in a fitting 

 state for positive determination. They 

 are strong, extremely narrow, with the 

 beak of the lower valve much produced, 

 and the inner edge of the upper valve den- 

 ticulated throughout. The muscular im- 

 pressions are dusky brown.
