First antennae showing no segmentation; second antennae very stout, with a swollen basal segment and a strong apical claw; terminal segment of maxilla clawlike, without teeth; terminal claw of maxilliped small, with an accessory spine at its base. Swimming legs very small, each a minute process tipped with two setae. Total length, mm. Remofrks.—Kr0yer and T. and A. Scott separate this species from cornutus^ but Hansen makes the two synonymous. If Scott's figures of the mandible and maxilla of the female of comutus and of the swimming legs of the male are correct, then surely the two species are distinct. The species may be identified by the characters given in the key and may be distinguished from comutus by the fact that the head is wider than long and the body is short and stout.
