is somewhat more costulate. Fleshy-white, with some livid spots 

 and stains. 20x8^ mill.

 light or grayish-brown. Whorls 10-11, flat, the first two uniform 

 light brown, second to sixth whorls densely and regularly rib-striate, 

 subsequent whorls nearly smooth, glossy, with fine growth-lines only ; 

 the last 3 whorls of about equal diameter. Aperture irregularly 

 ovate, tinted within. Parietal lamella strong, usually short. Axial 

 lamella distinct. Peristome reflexed, moderately or heavily thick- 

 ened ; the parietal callus usually strong, sometimes elevated.

The typical form (pi. 30, fig. 77) was small, 22-24x9 mill., smooth 

 and marbled. PfeifFer mentions the following forms : 



(b) Smaller, 1718 mill, long, 8 wide. Punta de Jicaco, (prob- 



ably Punta Icacos, N. from Cardenas). 



(c) Large, the last whorl plicate ; length 30, diam. 11 mill. Cayo 



Piedra. 



(d) Still larger, with strongly developed peristome and distinct 



rib-striae ; marbled ; length 36, diam. 11^ mill. Or marked 



with darker streaks. Cayo Blanco. 



The series before me shows all gradations between elaborately 

 marbled and uniform whitish and flesh-tinted specimens. Sometimes 

 the lower 4 whorls are smooth, sometimes the last is finely plicate at 

 the base or throughout, or at base and near the suture. These lead 

 to the form c?, which for convenience may be called form hologlyptum 

 (pi. 30, fig. 83), which is evenly and closely costulate throughout, 

 and either marbled with pale flesh-brown on a whitish ground, or 

 fleshy-brown, speckled with white, or with whitish riblets.
