 (Reeve}. 



"Shell ovate-conic, thin, smooth, pellucid, glossy, buff- 

 olivaceous ; spire convexly-conic, acute ; whorls 5, a little con- 

 vex, the last longer than the spire, more convex. Columella 

 straightened, callous, highly and shortly twisted-truncate. 

 Aperture little oblique, oval; peristome simple, unexpanded. 

 Length 11, diam. 6, aperture 6x314 mm." (P/V.)

'Very similar in general aspect to the preceding species 

 [bulimoides], but clearly distinct. It is less ventricose and 

 the columella is nearly straight " (Reeve).

The shell is imperforate, conic, thin, somewhat translucent, 

 very glossy, covered with a pale yellow cuticle. Spire 

 straightly conic, the apex obtuse, rounded; whorls 6U, 

 slightly convex, the last very obtusely subangular in the 

 middle, the base tapering and not very convex. The first 

 two whorls are convex and indistinctly, very minutely marked 

 with spiral lines; following whorls are irregularly, finely 

 striate over a very weak plication, which is hardly noticeable 

 except for a. short distance below the suture. The aperture 

 is trapezoidal. Columella very short, bearing a very strong, 

 spirally entering, median lamella. Length 10.5, diam. 6.2 

 mm. ; length of aperture 6 mm. 



Juan Fernandez (A. N. S. P. no. 10164). 



This form resembles F. 'biilimoides and consimilis in gen- 

 eral shape, but differs by the very strong median columellar 

 lamella and the subangular periphery. Neither of the speci- 

 mens is quite fully adult, the outer lip being sharp, without 

 the usual smooth finish.
