. Alaska. Natural history -- Alaska; Scientific expeditions; Alaska. 240 HOLMES large and elongated; hand oblong, broader and much longer than the carpus, the palm oblique, with a broad tooth at the posterior end and having a concavity in the center in which a large tooth is situated. Posterior persopods rather slender, with the basal joints comparatively narrow. Uropods slender and projecting backward to about an equal. Fig. 124. Gammaropsis ten distance, the first pair with the rami of equal length and a little shorter than the peduncle; outer ramus of the second pair shorter than the inner; rami of the posterior pair subequal and about as long as the peduncle. Telson nearly square, somewhat incised posteriorly, each lobe with a strong terminal spine and several setae. Length 9 mm. In the elongated gnathopods this species resembles Megamoplms, but differs from that doubtfully distinct genus in having a much longer secondary flagellum on the first antennae. From Gammaropsis crythroph- thalmus (Lillg.) this species differs in having more slender antennae and much more elongate and differently formed gnathopods. It is appar- ently more nearly allied to G. melanops Sars, but it differs from that species in having the postero-lateral angle of the first coxal plates strongly serrated, in having a longer accessory flagellum on the anten- nules, and in the form of the telson. From G. nana Sars it differs in having elongated instead of round eyes, in having a long accessory flagellum on the antennules, and in the form of both pairs of gnathopods.
