In this paper are given some records and descriptions of millipeds pertaining to several widely separated families as represented in the cabinets of the Chicago Natural History Museum. Other families have been reported upon elsewhere. This material has been studied through the courtesy of Dr. Karl P. Schmidt, director of that museum. Most of this material was collected by Dr. Schmidt himself and Henry S. Dybas, and much appreciation is due these men for their interest in the group.
