Wheeler) Disfrihution.—Tropical Pacific (Giesbrecht) ; Australia (Dana) ; North Atlantic (Cleve) ; California coast (Esterly) ; Narragansett Bay (Williams); Woods Hole (Wheeler, Fish). Color.—Body translucent to transparent, with a faint bluish or greenish tinge, just strong enough to make the living copepods visible over a dark background. Sometimes a bluish, greenish, or whitish pigment forms a few scattered spots, especially on the ventral sur- face around the bases of the mouth parts and the swimming legs. The eye spot is black in the center, but shows red around the edges. In the male the eye is farther back than in the female and dark red, and there is a patch of brown at the base of the mouth parts. Female.—Corners of fifth segment smoothly rounded, without spines; urosome one-third as long as metasome; genital segment as long as the abdomen and caudal rami combined; anal segment hairy on each lateral margin; second segment of fifth legs as wide as long; end segment swollen proximally, coarsely toothed centrally, abruptly.
