Hob. Sumba. 



This species might be regarded as a variety of G. trans- 

 versalis, Mousson. It differs in being much more distantly 

 punctate, in the smaller aperture, in the contraction of the 

 last whorl behind the peristome, and the somewhat greater 

 angularity of the edge of the umbilicus.
