GENERAL DESCRIPTION. 



F'.r.M. 



Base. Circular in youth ; dilating laterally with age, until the two sides, 

 curving round, meet and unite with a suture, forming a ring ; adherent to 

 the mouth of turbinate shells of Gastropoda, which it sometimes invests 

 with a horny membrane. 



Column. Exceedingly thin, low, and flat : the margin forming a low 

 sharp-edged parapet, with a distinct, but narrow fosse. Substance fleshy, 

 soft. Surface quite smooth for about one-third of the distance from the 

 margin to the edge of the base ; then it begins to be marked with fine 

 radiating depressed lines. These lines meet those from the opposite side, 

 where the two divisions of the body unite on the upper lip of the shell, 

 and alternating with them make a zigzag suture. The outer half of the 

 column is moreover generally thrown into irregular folds and puckers. 

 Loopholes numerous, large, pierced in the centre of slight elevations of the 

 skin, which are most conspicuous on the outer portions. 



Disk. Very long and narrow, smooth. 



Tentacles. Numerous, arranged in four sub-marginal rows ; nearly equal, 

 short, cylindrical, obtusely pointed, crowded, not completely retractile. 



Mouth. Protrusile, long, oval : the lips thrown into coarse folds, but 

 not furrowed ; throat and stomach marked with close-set white furrows.
