 striae. Aperture lunate; peristome sharp, evenly arcuate, within 

 the lip provided with one large white tooth in the basal region below 

 the periphery, and a smaller white tooth near the base of the narrow 

 columella.

 (Weinl.) is more elevated.

 (Pfr.), which has not been reported from Cuba before; also Vol- 

 videns ivichostoma (Pfr.), Urocoptis poeyana (Orb.), Guppya gund-

 four, sculptured wdth irregular incremental striae, and under a strong
