214 PROCEKDINGS OF THE M A LACO LOGICAL SOCIKTY. 



I found it ratlier difficult to determiue the generic position of this 

 little shell ; it has much the appearance of a \ erj minute Atnphip eras 

 (Ovidum), hut the minute columellar plaits seem to prove it 

 a Ilarginella. The exceedingly minute denticulation of the outer lip 

 is only perceptible under a powerful lens.

Ilab. — Trincoinalee, Ceylon. 



Of this elegant little species I have only seen a single specimen. 

 It is a very characteristic Ilucronalia, the inucronate apex consisting 

 of two small elate whorls ; the next three whorls have each two 

 narrow light-brown bands, one about the middle, and the other just 

 above the suture ; the last whorl exhibits a third band at the base, 

 not shown in the figure.

 convexi, laeves, sutui'a angustissinia sejuncti; anfractus ultimus 

 latus, convexus, ad basim truncatus ; apertura longiuscula, postice 

 angustata, antice latior ; columella callosa, triplicata, plicis validis, 

 postica lata, acuta, media obliqua, antica oblique contorta ; labrum 



crassum, leviter complanatum, intus minutissime denticiilatum, extns
