The rapidly accelerated descent of the suture after the 

 third whorl changes the shape of the shell, so that the addi- 

 tion of a half whorl gives it quite a different appearance. I 

 have therefore figured a series of shells from the Henderson 

 collection, taken at Jeremie, measuring 8.5, 10, 11.2 and 12 

 mm. long. This species and the next are remarkable for their 

 grooved surfaces, like Varicella. In 0. cleriei the second 

 whorl is distorted much more than in 0. microlestes.

The shell is small, lanceolate-fusiform, glossy, pale cor- 

 neous-yellow with occasional narrow darker streaks (but the 

 type specimens are bleached). The outlines of the spire are 

 slightly convex, becoming straight near the rather large, ob- 

 tuse apex. The first 1% whorls are smooth and enlarge rap- 

 idly; then the whorl becomes slightly narrower for a short 

 distance, after which it enlarges, at first slowly, but with in- 

 creasing rapidity, the suture becoming progressively more ob- 

 lique. The suture is broadly margined by transparence and 

 is quite irregular. The surface is marked with arcuate 

 growth-lines and has occasional impressed grooves marking 

 growth-stages. The thin outer lip curves well forward in the 

 middle. The columella is rather strongly concave, and is 

 abruptly truncate at base. Parietal callus thin but distinct. 



Length 8.9, diam. 2.5, aperture 3.9 mm.; whorls 5%.

This species is smaller and more slender than 0. cleriei or 

 the Cuban 0. subulata, and is doubtless distinct from both. 

 The specimens from Port-au-Prince are a trifle smaller than
