 Helix egena Gould, 1. c. nee Say. 



This is not egena 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. subperforata, turbinato-depressa, nitida, fulva ; anfr. 5 convexius- 

 culi, lente accrescentes, ultiraus basi subplanulatus, sub lente lineis con- 

 centricis sculptus, circa perforationem excavatus; apertura depressa, 

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

 1 1 mill.
