Testa minuta, aperte perspective umbilicata, fusca, striis incrementi 

 et spiralibus minute decussata ; spira parva, elata ; anfractus 4, 

 convexi, sutura profunda discreti, apicales magni, ultimus circa 

 medium concavus, supra et circa umbilicum obtuse angulatus, 

 antice solutus ascendens, aperturam vei'sus scrobiculatus ; aper- 

 tura tubaiformis, dentibus pluribus intus armata ; peristoma

In a natural condition all the shells are covered more or 

 less with agglutinated earth, which produces a rough irregular 

 appearance. There are five principal converging teetli within 

 the aperture, and a few smaller intermediate ones, none 

 reaching to the edge of the labrum. 



A species from Java in the British Museum, labelled 

 "//. Fruhstorferi^ Bttgr.," somewhat resembles the present 

 form ; it is, however, larger, has the last whorl less freely 

 produced, is keeled at the middle, and the spire is more 

 elevated.
