The trochanter has the apical piece more than twice as long as the basal piece. The hind leg is long and slender, and is provided with numer- ous long swimming hairs. The distal piece of the trochanter is much longer than the basal piece, appearing as a distinct joint. The Abdomen.—On the first segment the spacing humps are large and bulb-like; the lateral humps have no chitinous plates, but have a thick fringe of microscopic forward-pointing hairs. The lateral fringe is present, but is very weak. Large gills arising singly occur on segments 2 to 8, inclusive. Except for the drag- hooks the prolegs are not chitinized. 101.
