Apertura labiis cancellatis, cancellis transversim striatis.
I found this beautiful little shell among a collection of chiefly West India shells. According to the Linnaean system, it would come under the genus Turbo; but with the advice of Dr. Leach, I have distinguished it as a genus, under the title of Cyclostrema. Helix depressa and serpuloides of Montagu are referable to the same genus.
