 lique, linear, divided at its base by a single strong, sharp, ob- 

 liquely ascending columellar plait ; peristome simple, sharp ;

5. Melampus bullaoides. B.M. ? 



" Shell ovate, pale horn-colour, inclining to purplish-brown at 

 the tip, with eleven or twelve flat whorls ; these are not divided 

 by any depressed line, but each folded over the other, leaving 

 the edge abrupt, and not turned inwards : the body volution 

 consists of three-fourths of the shell, those at the top not only 

 extremely small, but the four or five last decrease so suddenly 

 that they form a nipple on the shell, like the stjde on the top of 

 an acorn, and which it much resembles; the apex is more 

 minute than in any shell of its size we ever remember to have 

 seen : the aperture is much contracted ; the outer lip extends 

 about half the length of the shell ; the pillar lip quite smooth, 

 without any duplicature, but at the base, or lower part of the 

 aperture, the outer lip makes a short revolution, enters the 

 aperture, and forms a strong plication or ridge on the columella, 

 the spiral turn of which may be traced through the shell, 

 although considerably thick and opaque ; the sudden flexure of 

 the lip that forms the spiral ridge on the columella forms also a 

 sort of canal or gutter." (Mont.) Length f in.
