The region embraced in these studies lies between MD & TX. It comprises the faunas of the various watersheds of this part of the Atlantic & Gulf slopes. Frequent comparison with many of the drainages of the TN & MI valleys has been necessary; much of the material reported from those areas has been re-examined. The inception of this report, however, begins with the collections made by Francis Harper from 1930-1945. The lots of fishes he gathered during his southern trips have been studied. Extensive noteworthy collections were made by Joseph Galloway. These were supplemented by Fowler¿s own collecting trips & the staff of the Acad. of Nat. Sci. of Phila. in NC in 1940, & of the Southern Piedmont-Coastal Plain Aquatic Survey of 1941 & 1942. Illus.
