Two small collections of shells obtained from Maya ruins in British Honduras have recently come to hand, and it has been thought worth while to record the species found, both from a conchological and archaeological viewpoint. When shells are found in archaeological sites, their classification and correlation of original habitats often permit interesting deductions to be made concerning trade routes or relations.

The first set was collected by Dr. Thomas Gann from a crystal burial mound near Rio Hok Skum. The locality is near Corozal in the northern part of British Honduras and about thirty miles from the boundary of Quintana Roo, Mexico.
