 lems presented by these miniature Oleacinas are exceptionally 

 difficult.

"Shell ovate, very glossy, under the lens very lightly stri- 

 ate, subtranslucent, greenish brown. Whorls 6 to 7, very 

 slightly convex, separated by a lightly brown-margined 

 suture, which descends more rapidly from the antepenulti- 

 mate whorl ; last whorl three-fifths the total length, rounded 

 at base. Aperture irregularly ovate, narrow, rounded bas- 

 ally; peristome acute, bending forward in the middle; col- 

 umella contorted and abruptly truncate at, the base ; parietal 

 wall covered with a very thin but distinct callus. Alt. 20, 

 diam. 8, aperture 12 mm." (Maltzan).

A smaller, more regularly fusiform species than the Cuban 

 0. straminea, with strictly conic spire, less concave columella, 

 and yellow instead of reddish streaks. The aperture is nar- 

 rower at and above the middle, the outer lip more distinctly 

 arching forward in the middle, and having a smooth, obtuse 

 edge, not so thin and acute as it usually is in 0. straminea. A 

 considerable series before me, collected by Salle, Gabb, Hen- 

 derson and Simpson, shows this form to be quite constant. 

 The description of Maltzan is imperfect in several details. 

 The color of fresh specimens is greenish yellow, with irreg- 

 ularly spaced olive-yellow streaks. The suture has a pale 

 border, edged with gray below. The aperture is not ' ' ovate, 

 but rather lanceolate, and the outer lip is strongly retracted 

 above the middle. The whorls increase regularly to the last,
