14: Descriptions of Thirty Supposed New Specie and 



moderately coarse oblique strife of growth. Keel nearly ob- 

 solete ; last whorl very much rounded, and brownish. Spire 

 with convex outlines. Apex truncate with the loss of f 

 whorls ; 7j- whorls left, very convex and rather shouldered, 

 with a deeply impressed suture ; last whorl moderately 

 produced, subangular on the right side, and at the upper 

 part of the left. Aperture large. Lip spreading much on 

 the left lower extremity ; thin, shining, and slightly 

 reflected. Length .67, breadth .17, breadth of lip .17. 

 Habitat, near Maroon Town, St. James. 



ACHATINA PA.RVULA. Shell sub-cylindrical, whitish with 

 a yellowish epidermis, with strong transverse strias on the 

 last 5 whorls, becoming obsolete on the lower extremity of 

 the last whorl. The apex quite free from striae Spire with 

 almost rectilinear outlines. Apex very obtuse. Whorls 7, ra- 

 ther turretted ; last whorl much bo. At one half of the 

 labrum, the aperture is singularly constricted, and there is 

 a hir^e opal white tooth, at the point of constriction ; thence 

 it is very abruptly truncated, and the labrum thickened ; 

 the columella is considerably thickened ; and is also of an 

 opal white. Aperture very long, much twisted and sub- 

 angular above. 



Mean divergence about 12. Length .14,

ACHATINA ADAMSIAXA. Shell conic, very slender ; ground 

 color very light brown, with rich dark burnt umber transverse 

 ban Is, light on the right and becoming dark gradually on 

 the left side. There are three of these bands, with the in- 

 tervening light brown on the last whorl. Upon the last 7 

 whorls there are very strong rounded waving ribs, 20 on the 

 last whorl, and decreasing in number upwards ; these are 

 decussated by numerous spiral ridges. Between the ribs, 

 are very numerous microscopic striie. The ribs of each 

 whorl project over the preceding one, causing the shell to 

 be coronated. Above the?e T whorls, up to the the apex.
