"By its shape, conic and thin, this species approaches A. 

 unilamellata, but it differs by lacking the projecting lamella, 

 by the infinitely smaller size, and by the more swollen, less 

 numerous, whorls of the spire " (Orb.). 



Orbigny's type (pi. 40, fig. 18) was apparently a very 

 young shell. This view was taken by Pfeiffer and the Cuban 

 authors generally. It has been lost (see Pfr., Malak. BL, v, 

 p. 185). The species when adult, fig. 19, varies from imper- 

 f orate to distinctly perforate, and is oblong-conic or turrite 

 in form, milky-whitish, somewhat translucent, thin, finely, 

 irregularly striate. Spire straightly conic. Whorls 6%, sep- 

 arated by a deeply impressed suture. The earlier whorls are 

 quite convex, the last compressed or flattened above, some- 

 times with an impressed line in the compression, parallel to 

 the suture ; convex peripherally and beneath. Aperture some- 

 what oblique, ovate, the outer lip straightened above, slightly 

 arched forward. Columella very short, straight or concave, 

 broad, deeply truncate below. 



Length 8, diam. 3.2, aperture 3 mm. 



Length 8.6, diam. 3, aperture 3.1 mm. 



It is more lengthened than L. pallida Ad. of Jamaica, or 

 L. salleana of Haiti, but it is closely related to both. There 

 is a stouter and a more slender form, as indicated by the 

 measurements above, and noticed by Pfeiffer. 



Bulimus paludinoides Anton, Verzeichniss, p. 42, no. 1534 

 (1839), is probably a Paludestrina.
