Terminal claws of first leg less than one-third longer than the last three segments. Furca weakly S-shaped to nearly straight, and from eighteen to twenty times as long as wide. Terminal seta of furca weak, not more than one- third as long as terminal claw; dorsal seta less than width of furca from subterminal claw and about one-half as long as the terminal seta. Sexual.

Length to mm., height mm., width mm. Shell usually reticulate or tesselated. Somewhat superficially resembling Cypris fuscata major. Natatory setae reach slightly beyond the terminal claws. Furca straight, weakly bent near the end, and from ten to twelve times as long as wide, and â faintly toothed along the dorsal margin. Terminal seta slender and of the same length as the dorsal one, which is situated about width of furca from subter- minal claw. Abundant in small, temporary grassy pools.
