1 3 Mr. Cuming informs me that he has 
forwarded no less than six distinct Vni- 
ones from Ceylon to Isaac Lea, of Phila- 
delphia, for 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.
