So far as known this species is confined to the areas of Virginia indicated by the symbols. waters of the Roanoke River, but in recent years specimens have been collected from the Mayo River and headwaters of the James River system adjacent to the Roanoke River. Specimens of Noturus leptacanthus and N. insignis have been reported as gilberti. Etymology.—Noturus gilberti was named for Charles Henry Gilbert, an outstanding American ichthyologist. Relationships.—The species is very distinct and does not appear to be closely related to any other kind of Noturus. It is assigned to the subgenus Schilbeodes because of its common characters, but in some respects, chiefly color pattern, number of paired fin rays, and vertebral elements, it resembles Noturus jiavus. Ecology.—Hubbs and Raney (1944, p. 24) indicate that N. gilberti was taken from a rubble riffle. Specimens seem to prefer to hide in relatively fast water riffle habitats, beneath large stones and debris that is not swept away by the current. Noturus insignis is a common associate of gilberti. Subgenus Noturus Rafinesque The subgenus Noturus contains only one species, Noturus jiavus Rafinesque, the type-species of Noturus. N. Jiavus has been placed in Noturus since recognition, except for irregular inclusion in the genus.
