In the female the gnathopods are much shorter and weaker than in the male; the hand in the first pair is less elongated, and the palm is more oblique and more broadly rounded at the outer angle. In the second pair the sinus in the palm is not so deep, and the outer angle not so prominent as in the male. Peduncle of the first pair of pereopods rather slender, much longer than the rami, and reaching nearly to the tip of the peduncle of the second pair; inner ramusof the second pair of uropods about as long as the peduncle. Posterior pair of uropods with the rami scarcely half as long as the peduncle; rami subequal in length, the broader, more 'or less oval inner one with a short spine at the inner posterior angle and several setae on the transverse distal margin; outer ramus with the usual stout hooks. Length 6-9 mm. In the older specimens the antennae are relatively more elongated, and the hands of the male relatively longer and narrower. The eyes in the living specimens are red, but become black in specimens preserved in Habitat. The range of this species as reported by Professor Smith is from Vineyard Sound to New Jersey, and it has been reported from Provincetown, Mass., by Richard Rathbun. It is not uncommon among the seaweed near the shore, and it has been taken at the surface in the vicinity of Woods Holl in the tow net. Its occurrence at the surface is probably due to its having been carried away from the shore by tide currents, as it has a strong tendency to keep among objects of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass.
