Occu'i-rence.—There is as yet no record of this species within the present area, but both sexes have been captured so close at hand that it is Hkely to appear at any time in the future.

Lincei, Rome, ser. 4, vol. 4, p. 336, 1888. Occu'i-rence.—There is as yet no record of this species within the present area, but both sexes have been captured so close at hand that it is Hkely to appear at any time in the future. Distribution.—North Pacific (Giesbrecht); North Atlantic (Wolf- enden, Farran) ; Malay Archipelago (A. Scott) ; California coast (Esterly) ; North Sea (van Bree- men) ; Denmark Strait, Faroe Channel, Iceland (With); Gulf of Maine (Bigelow). Color.—Body fairly transparent, with red pigment scattered along the dorsal midline, on the basipods of the swimming legs, and in the plumose setae of the second an- tennae, as in the other species. Female.—Forehead with a high crest, but with only a vestige of a rostrum; urosome less than one- sixth as long as metasome and per- fectly symmetrical; genital seg- ment protruding ventrally; none of the caudal setae elongated; exopod of second antennae four times as long as endopod; end segment of latter with 3 and 2 setae; basipod of fourth leg with a row of 12 or 13 spines running from the inner margin along the posterior surface. Total length, mm. Male.—Forehead with a crest, without a rostrum; first antennae extending little beyond the cephalothorax; exopod of second anten- nae only one and one-half times as long as the endopod; fifth legs biramose, endopods 1-segmented, left exopod 3-segmented, right 2-segmented; the two legs about the same length. Total length, mm. Remarks.—The species may be recognized by the high crest, the 5 setae at the tip of the endopod of the second antennae, and the row of 10 to 13 short spines on the basipod of each fourth leg. In the male the structure of the last segment of the right fifth exopod is the most characteristic Figure 38.—Euchirella curticauda: a. F
