EULIMA. 201 



Shell awl-shaped, many-whorled, polished and lustrous, 

 not umbilicate: spire finely tapering to a regular point, with 

 an extremely slight suture or line of separation between the 

 whorls: mouth pear-shaped; lips discontinuous: operculum 

 horny, with a short and incomplete spire, having its nucleus on 

 the colamellar or inner side. 



From the absence of a spinous tongue, or " odonto- 

 phore/' it may be inferred that the mode of feeding is 

 suctorial, as in Odostomia and Stiiifer. It also shows 

 that this organ is not indispensable for the classification 

 of the Gastropoda. Forbes says that the animal of 

 Eulima creeps with the foot greatly in advance of the 

 head, which is almost always concealed beneath the 

 front edge of the shell, the tentacles alone protruding. 

 Scacchi and Philippi noticed the peculiarity of the eyes 

 being apparently withdrawn, and peeping out under 

 cover of the shell. The shell has an enamelled surface, 

 shining like porcelain. There are many species, recent 

 and fossil. None inhabit very high latitudes. 



Other names of this genus are Pasithea, given by Dr. 

 Lea, and Balcis, by Dr. Leach.
