						Girdle:  Wide with sparse flat glassy hairs having several recurved spines at the base.  Mucro:  Strongly posterior.  Valves:  Beaked slightly.  Central areas:  Longitudinally ribbed and where each rib touches the lateral area there is a granular pustule.  Pustules:  Form a heavy lateral rib;  from this rib the central area rib continues at an oblique angle on the lateral areas until it again reaches a granular pustule at the posterior edge of the valve;  pustules form another granular rib along the posterior edge of each valve. Color:  Ranging from dull gray, grays with white, greens with yellows, whites with yellows, greens with red, greens with maroon with white mixed in (Ref. 296).  Body:  Oval to elongate (Ref. 290).
