Var. subcarnea Poll. PI. 43, figs. 11. 



Differs from the type by the slightly more swollen shell, 

 the spire less regularly tapering, last two whorls more rapidly 

 widening. Length 11 to 11.5, diam. 4, alt. apert. 4.5 mm. 

 Same locality. 



Probably the shell described and figured by Benoit from the 

 island of Alicuri, under the name Achatina lamellifera Morel., 

 is a form of F. carnea, as Kobelt has surmised.

Shell oblong, rather short, very glossy, pellucid, corneous, 

 polished; spire a little produced, suboblong, rather abruptly 

 truncate and at the summit slender, subcylindric ; apex min- 

 ute, a little obtuse. Whorls 7, slightly convex, the first 4 very 

 small and narrowly coiled, fifth larger and the rest relatively 

 very large, separated by a paler linear suture ; last whorl large, 

 half the total length, a little convex. Aperture vertical, ob- 

 long, very angular above, somewhat widened at the outer 

 basal margin, whitish and bilamellate within, one strong la- 

 mella at the columella, the other, tooth-like, at the upper part 

 of the columella. Columella short, white, straight, acumi- 

 nate ; peristome straight, a little obtuse, thickened within and 

 whitish. Outer lip strongly arched forward, the margins 

 joined by a strong callus. Length 11, diam. 3.25, aperture 

 5.5 mm. (Bgt.)
