Original description.
A color form of tliis species has the posterior and mechan keel wliite, wliile the supra-peripheral one and the base are light brown. I will suggest for this form the varietal name, hicolor, fig. 6, Cat. No. 195376, U.S.N.M., dredged hj the Fisheries steamer Alhatross at the same station. Another specimen of this form was found among C. B. Adams type lot of Triphoris alfernatus from Panama.
