This species resembles L. hunguranensis in colour and the 

 spiral striae, but differs in its more conical form, narrower 

 umbilicus, and thinner epidermis. The operculum is very 

 thin, yellowish, and consists of about ten volutions.

The epidermis of this })rctty species has a somewhat silky 

 appearance and is very finely lamellated m the direction of 

 the oblique lines of growth and very shortly setose upon tlie 

 spiral lira; ; these usually number two or three on the upper 

 whorls and five or six on the last, the one at tlie periphery 

 being a trifle more conspicuous than the rest. When present 

 the red markings radiate from the suture and extend some- 

 what zigzag over the body-whorl.
