THE NAUTILUS. 



55 



Paludestrina? sp.? A single specimen that I can not ap- 

 proximate to any of the described species. 



This is the first record, I believe, for Plecotrema cubense from 

 the mainland of Florida. Originally described from Cuba, it 

 was listed from the Bermudas by Dr. Pilsbry in 1900, (Trans. 

 Conn. Acad., X, p. 504, pi. Ixii, fig. 11), and there figured by 

 him for the first time. Both he and Mr. John B. Henderson 

 inform me that they have collected it on several of the Keys 

 and I am indebted to both of them for the opportunity of com- 

 paring my specimen with theirs.
