THE NAUTILUS. 11 



Alt. 15'0; Ion. 18'0 ; long, of post-umbonal part ll'O; diam. 8'0 

 mru. Habitat from Curacao and St. Thomas, West Indies, to Cedar 

 Keys, Florida, from low water to 26 fathoms ; Chas. T. Simpson 

 and other collectors, in the U. S. Nat. Museum. 



This is probably the species which has been identified by Antil- 

 lean collectors with Circe (Lioconcha) hebrcea (Lam.) Sowerby, but 

 it is a smaller shell and a true Meretrix, represented by specimens 

 from seven localities in the Museum collection and noted in Bull. 

 37, U. S. N. M., p. 56, No. 285 in 1889.
