300 ANTILLEAN LEPTINARIA. 



Haiti: Port-au-Prince and 8 miles westward (Henderson 

 and "Simpson). 



This species is related to L. striosa C. B. Ad., but it is far 

 more slender with a smaller apex, and with more whorls in 

 shells of the same length. Most of the specimens taken were 

 smaller than the above dimensions, 7 mm. long with 8 whorls. 



7. L. SALLEANA (Pfeiffer). PL 44, figs. 60, 64, 65. 



Shell subperforate, conic-oblong, thin, striatulate, slightly 

 shining, waxy-whitish. Spire turrite, the apex rather acute. 

 Suture lightly impressed, simple. Whorls 6, flattened, the 

 last slightly exceeding one-third the total length. Columella 

 short, truncate, twisted inward. Aperture oblong-semioval ; 

 peristoine simple, unexpanded, the columellar margin dupli- 

 cate-reflexed, forming a perforation. Length 7, diam. 3, aper- 

 ture scarcely 3 mm. long, 1 wide (Pfr.) . 



Haiti: near the city of Santo Domingo (Salle, H. Prime) ; 

 Rio Ozama (H. Prime).

"Very like A. anomala Pfr., from Which it chiefly differs 

 by the flat whorls and narrow aperture" (Pfr.). Pfeiffer's 

 figure of the type is copied, fig. 60. When fully adult (figs. 

 64, 65) the shell is larger, length 8.3, diam. 3.7, aperture 3.1 

 mm., with fully 7 whorls, or a little narrower, 8 x 3.3 mm. 

 The whorls in a large lot of specimens before me are not 

 especially flattened, and the suture is more deeply impressed 

 than would appear from Pfeiffer 's description. The surface 

 is distinctly arcuately striate, and the perforation is usually 

 well open, though rarely closed in the narrower shells. The 

 columella has a stout tooth-like callus superposed upon the 

 inner edge of an Opeas-like reflexed margin. Within the last 

 whorl a stout callous fold revolves very obliquely around the 

 column, but in earlier whorls the axis' is slender and only 

 very weakly sinuous.
