periphery, but a short distance above the keel. Behind the 

 white outer and columellar lips there is a fleshy or brownish- 

 pink streak, interrupted by the white keel, below which there 

 is an ill-defined band of similar color. These markings show 

 inside the aperture. Surface glossy, nearly smooth except 

 behind the lip, where it is densely and minutely striate. Keel 

 very strong on the last half whorl, merely traced on the first 

 half. Aperture oblong, much longer than wide, the lip thick- 

 ened, well expanded, sinuous, whitish, both outer and colu- 

 mellar margins retracted above, joined by a whitish parietal 

 callous. Columella more or less distinctly truncate in oblique 

 view, thick inside (pi. 11, fig. 77). Length 20, diam. 6.2 mm., 

 whorls 8, or a little smaller, 18.5 x 5.5 mm.

The axis is strongly thickened within the last whorl (pi. 11, 

 fig. 77), quite unlike the slender axis of var. bicincta (fig. 78). 

 This, the preceding and the following varieties are from 

 central Jamaica, and are widely separated geographically 

 from the western levis and var. bicincta. Perhaps they form 

 a distinct species, as no intermediate forms, either structurally 

 or geographically, are known.

Shell similar to var. unicincta except that the entire lip is 

 of a brilliant rose-red, and the olive band above the suture 

 ascends to the summit, becoming darker on the upper and on 

 the last whorls; elsewhere the shell is glossy, opaque- white, 

 without the gray streaks of var. unicincta, or with them very 

 faint. The black band on the last whorl runs into the color- 

 streak behind the lip. Columella truncate. Surface smooth, 

 under a strong lens showing excessively minute, close striae on 

 the early whorls, a dense, shallow pitting on the intermediate 

 whorls, and fine striation, as in unicincta, on the last whorl. 

 Length 17, diam. 5.7 mm.
