This is not eg-ena Say, as stated in the remarks under 

 H. chersina. Having sent some of the specimens received 

 from Gould to PfeifFer, I have received from him an 

 assurance of their being identical with his Gundlachi^ a 

 Cuban species. His description is as follows : — 



T. subpeiforata, turbinato-depressa, nitida, fulva ; anfr. 5 convexius- 

 culi, lente accrescentes, ultimus basi subplanulatus, sub lente lineis con-« 

 centricis sculptus, circa perforationem excavatus ; apertura depressa, 

 lunaris ; perist. simplex, rectum, acutum. Diam. maj. 2^, min. 2^^, alt.
