Only one of the specimens is dextral; v. Martens records dextral and sinistral specimens 

 for his var. infraviridis. The Siboga-specimens mainly agree with the figures of that author, 

 being less elongate than his fig. 5, but more so than fig. 8.

The specimens are small, more or less young, but especially the largest one is easily 

 recognizable by the waved sculpture, which is only partly visible in the smallest specimen. This 

 latter agrees with Reeve's words "obscurely freckled with chestnut". I find these freckles in 

 many specimens from other provenience, particularly if seen by translucent light.

The specimen, which seems to have been inhabited by a hermit-crab, having lost its 

 columellar folds, agrees in shape of spire with fig. 7 of v. Martens, but its aperture is broader 

 below, nearly as in his fig. 1 1 , though the peristome is thinner.
