138 OLEACINA, CUBA. 



mare whorls. No such shell is now known from Haiti. If 

 not Haitian, then oleacea must have been based on Cuban 

 shells. In Cuba, the form from Matanzas approaches most 

 closely to the requirements of Deshayes' description and 

 figure. 



Pending a decision as to the identity of 0. oleacea, we may 

 consider the Cuban shells a subspecies, since they differ in 

 various respects from the type figures of oleacea. 



Cuban species of L&voleacina. 



A few Cuban species are here figured and described to fix 

 definitely the identity of the forms I have dissected, and of 

 the type-species of Lavoleacina. 



Sa. 0. OLEACEA var. STRAMINEA (Deshayes). PI. 33, figs. 5-9. 



The shell is oblong-cylindric, thin, greenish-yellow, with 

 arcuate, irregularly-spaced reddish streaks; very smooth and 

 glossy, without microscopic spiral stria?. Spire conic, with 

 slightly convex outlines and obtuse apex. Whorls regularly 

 increasing; the suture descends regularly and is not notice- 

 ably more oblique at the last half-whorl. It is margined by 

 transparence, and in old shells the last whorl may have an 

 impressed marginating line. The outer lip is very thin and 

 sharp, well curved forward in the middle. The short colu- 

 mella is very concave, colored like the shell except for a pale 

 edge, 'and abruptly truncate at the base. Deshayes' figured 

 type measured 37 x 13 mm.
