This well-known shell probably occurs in the Pleistocene of the Florida 

 Keys, and is found in the recent state from Bermuda to Brazil and also on the 

 west coast of Africa. Its synonymy has been so much confused that it seemed 

 well to include it here to clear up the name, since it is the type of Jagonia 

 Recluz, and was described originally by Montagu as a British shell from an 

 adventitious specimen. It is quite distinct from the true Lucina pecten of the 

 Mediterranean described by Lamarck, though the name of pecten has fre- 

 quently been applied to the West Indian species erroneousl)'. It is possible 

 that some of the well-marked varieties of this species will be eventually raised 

 to specific rank, but at present I am obliged to regard them as varieties only, 

 as noted in the above synonymy.

Pliocene of the Caloosahatchie beds, Florida, Griffiths ; living at San Juan 

 and Mayaguez, Porto Rico, United States Fish Commission. 



This curious little species is about half way between a typical Jagonia and 

 a Parvilucina. It appears to be rare in the marls and was obtained only by 

 Dr. Griffith, who presented specimens to the Wagner Institute.
