Cerion regina brevispira P. and V. 



Shell short, pupiform, compact ; lower two whorls of equal diam- 

 eter, those above tapering to form a short cone. Whorls 8-9, all 

 but the last one smooth, the last more or less ribbed ; umbilical 

 chink deep, the area below it excavated. Aperture much exceed- 

 ing one-third the length of shell, ovate, purple within; peristome 

 narrowly reflexed, not thickened, white; parietal callus impercep- 

 tible; parietal lamina small, rather short, deep-seated. Axial 

 lamina small. White, boldly streaked and blotched with rich 

 brown. Alt. 22, diam. 10 mm. or smaller. Apert., alt. 9.5; width 

 8.3 mm. Turk's Island. (W. M. Gabb.) 



This form looks very distinct from C. regina, and we have no 

 intermediate specimens; but it occurs on the same small island, and 

 may prove to be only a sub-species of that form. 



Cerion (Maynardia) maritimum var. sublaevigatum (Pfr.) P. and V. 



Similar to maritima, but lacking costulse. Matanzas, etc., Cuba. 

 (Strophia maritima Maynard, Monogr. p. 127, seems to be this, 

 rather than the typical maritima.) 



Cerion (Maynardia) abacoensis P. and V. 



Shell like Cerion album Maynard in form, sculpture and color, 

 or rather shorter; differing in the more closed, shallower, far shorter 

 umbilical rimation and very much smaller umbilical area behind • 

 columellar lip, and in the thicker lip. Alt. 32; diam. 12| mm.; 

 alt. 27i; diam. 13 mm. Abaco I. (Bland.). 



Cerion (Maynardia) incanoides P. and V. 



Shell resembling C. incanum in general aspect. Very thin; 

 cylindrical, the lower three whorls of equal diameter, those above 

 forming a convex, obtuse cone. Surface nearly smooth, as in S. 

 incana; white or fleshy-white, the two nepionic whorls corneous 

 brown, the following whorls of cone finely variegated with zigzag 

 brown marking and speckling. Whorls 10, almost flat. Aperture 

 ovate-truncate, brown inside; parietal lamina low and rather short; 

 axial lamina sharp, strong within last whorl, but not over a whorl 

 long ; peristome narrowly reflexed, white, thin ; parietal callus rather 

 thin ; umbilical rimation deep, sometimes perforate, the area below 

 it broad, excavated, flaring. Alt. 30; diam. 11 mm.; alt. of apert. 

 11; diam. 9 mm. Turk's Island.
