gnathopoda very nearly alike; hand oblong, slightly widened distally with an oblique, gently convex 

 palm which terminates posteriorly in a rounded elevation furnished with a lew slender spines; tirst 

 and second perseopods with carpus scarcely half as long as merits and about two-thirds the length of 

 the very narrow propodus; dactyl nearly straight and over half length of propodus; third perseopods 

 with basal joint oblong, slightly concave in front and slightly convex behind; merus a little wider 

 than long; carpus quadrate, broadly expanded, armed with stout spines; propodus much narrower 

 than carpus, hut about as long, armed in front with three fascicles of stout spines; dactyl slender, over 

 half length of propodus; fourth perseopods stouter than in oculatus; carpus shorter than merus or 

 propodus, and, like those joints, armed with fascicles of strong spines; dactyl styliform; fifth perseopods 

 with basal joint expanded much as in oculatus; merus slightly longer than carpus; dactyl slender, the 

 tip turned slightly forward; posterior margin of lateral expansions of third abdominal segment 

 furnished with several seta-; first uropods with rami nearly as long as peduncle, the inner ramus with 

 u ually a single spine near middle and the outer with two or three spines on the liasal half of upper

 beyond the first; rami furnished with plumose set* on both margins, outer ramus with a few short 

 spines on outer side; telson longer than broad, the lob.es distally rounded.

Numerous specimens were examined, but they were apparently all males and unfortunately the 

 •terminal joints of the first antenna' had in all eases been broken off. In the type species..!' Para- 

 phoxus l /'. oculatus) the two pairs of antenna' in the female are of nearly equal length, the eyes of the 

 female are very much smaller than those of the male, and the terminal uropods smaller, much more 

 unequal in size, and devoid of the marginal plumose setae found in the male. It is probable that 

 similar sexual differences will be found to occur in the present species. 



This species may he distinguished from oculatus by its stouter appendages. In the third perseopods 

 the merus is relatively shorter and broader and the carpus broader than in oculatus; the joints of the 

 fourth perseopods are much stouter and armed with strong spines. In oculatus, according to Sara's 

 figure in the Crustacea of Norway, there are in. setse on the posterior margin of the lateral expansions 

 of the third abdominal segment.

Rostral hood extending beyond the antennular peduncle, eyes wanting; first antennae nearly as

 end of lower margin; second joint produced somewhat at distal end of lower side, where it hear-
