Panama Shells. 27 



that name, off the coast of Guayaquil, near Cape San Lorenzo, 

 in latitude 1 10'. It is only 4 miles long and 1 1-2 broad. 

 Mr. Sowerby's reference to Mexico is unintelligible. Two 

 specimens received by us from a German conchologist, are said 

 to have come from Chile, but Ihis is a very doubtful habitat. 

 We collected 8 living specimens at the end of the reef at 

 Panama, and 20 dead shells in the vicinity.
