Occurrence.—Three females in a vertical haul, Station 20044, Grampus, south of Georges Bank. Distribution.—Tropical Atlantic and Pacific (Giesbrecht, Brady); Gulf of Guinea (Lubbock) ; Abrolhos, Australia, Caldera, Chile (Giesbrecht); California coast (Esterly); North Atlantic (Brady); Gulf of Maine (Bigelow). Color.—Body somewhat opaque, with red pigment above the mouth parts, along the median axis, and on the basipods of the swimming legs. The densely plumose setae of the second antennae are also pinkish or reddish and stand out conspicuously as in other species of the genus. Female.—Forehead with a low crest and a small rostrum; uro- some about one-fourth as long as metasome; genital segment asym- metrical, with a stout protuber- ance on the left side of the dorsal surface and an indentation on the right side; exopod of second antenna two and one-half times as long as endopod; end segment of the latter with six and five setae; basipod of fourth leg with one or two spines on its inner margin. Total length, mm. Male.—Forehead with a crest and a rostrum; urosome symmetrical; anal segment very short and divided at the center so as to cause the caudal rami to appear 2-segmented; fifth legs biramose, left endopod so rudimentary as to be easily overlooked; chela on right leg shorter than the basipod; right exopod 2-segmented, proximal segment with three angular protuberances on inner margin, distal segment with a series of fine tubercles. Total length, mm. Remarks.—This species may be distinguished by the presence of a crest and by the relative lengths of the rami of the second antennae
