IT. Lucina scabra Reeve (Lam.?) 



Lamarck cites Tellina muricata Chemn. in his synonymy of 

 L. scabra, without assigning any reason for changing the name. 

 Mr. Keeve uses the Lamarckian name for this West Indian spe- 

 cies, but applies the Chemnitzian name to a Peruvian species 

 obtained by Mr. Cuming. 



Habitat. — One large and several smaller specimens were 

 obtained with L. pectinella.
