OLEACINA, HAITI. 133 



which descends much more rapidly. Adult specimens from 

 La Ferriere a, Charmettes &, and Santo Domingo c, measure : 



a. Length 21.3, diam. 8, aperture 12 mm.; whorls 6y 2 . 



6. Length 19, diam. 7.25, aperture 11 mm. ; whorls 6Vs- 



c. Length 20, diam. 8, aperture 12 mm. ; whorls 6. 



Specimens collected by Salle, and hitherto reported as 0. 

 oleacea, prove to be 0. miilleri. The true 0. oleacea has not 

 yet been found in Haiti. There is some doubt about what 

 the original oleacea really was ; the figure has a suspicious re- 

 semblance to 0. miilleri, yet it is larger than any Haitian 

 specimen actually known, and, according to Deshayes' de- 

 scription, it had more whorls. 



3. 0. SMITHIANA Pfeiffer. 



Shell subfusiform-cylindric, rather solid, smooth, glossy ; 

 bluish-white, marked sparsely with fulvous streaks. Spire 

 convexly conic, the apex obtuse, suture slightly impressed, 

 broadly margined. Whorls 6, but slightly convex, the last 

 forming nearly two-thirds the length, slightly tapering bas- 

 ally. Columella arcuate, abruptly truncate above the base of 

 the aperture. Aperture vertical, acuminate above, rounded 

 basally, pearly inside ; peristome simple, unexpanded, the 

 right margin lightly arched forward. Length 16.5, diam. 

 5.66, aperture 11x2.5 mm. (Pfr.). 



Haiti: Mt. Platon (Smith, type loc.) ; environs of Jeremie 

 and Gonave Island (Weinland) ; Port-au-Prince (Dr. Brown).

This species has not been figured. Whether the shells com- 

 mented on by Weinland, from Jeremie, Port-au-Prince and 

 Gonave Island are identical with Pfeiffer's type remains un- 

 certain. The type locality, Mt. Platon, is about thirty miles 

 northeast of the Haitian town Les Cayes.

The cylmdric-fusiform shell is decidedly smaller than 0. 

 smithiana, smooth except for faint growth-lines; suture mar- 

 gined with a whitish followed by a gray line, the last whorl
