This species resembles C. yumaense var. sallei of S. Domingo, but its apex is less obtuse, the peristome much thicker, and the ribs stouter. The specimens described were received from Mr. G. H. Clapp, and collected by Mr. C. B. Taylor, of Kingston, Jamaica, who found them on a "honeycomb" lime rock and red earth formation, on the north side of the island.
