Helix Jajana, C. B. Adams {Sagda). 



Like Sagda connectens C. B. Adams and Sagda Haldemaniana C. B. 

 Adams (see Amer. Jour. Conch. VII, p. 175), this, also a Jamaica species,

Jaw smooth anteriorly, with scarcely any median projection to its 

 cutting edge. 



This is an additional proof of the position of Sagda
