Remark*. This new genus is nearly allied to Phoxoceplwlns, though 

 differing markedly in the structure of the mandibles and in the <-<|ual-sized 

 gnathopoda, in which respect it would seem to form a transit.. rv link to the 

 genus Harbin/a, with which genus it also agrees as regards the outer habitus. 

 The species upon which the genus is founded, was formerly referred l>y tin- 

 author to the genus Phozus (now* Phoxocephalus).

Body in female rather short and tumid, in male somewhat more com- 

 pressed. Cephalon nearly attaining the length of the 4 anterior segments of 

 mesosome combined, hood evenly vaulted above, with the terminal edge roun- 

 ded in front. First pair of coxal plates scarcely broader than the succeeding 

 ones, distal edge subtruncated, and bearing about 14 bristles; the 2 succeeding 

 ones regularly quadrangular, each with about 8 bristles occupying the posterior 

 half of the distal edge; 4th pair fully twice as broad as the preceding ones, 

 the inferior and posterior edges forming together an even curve, upper corner 

 rounded; 5th pair with the posterior lobe scarcely widening below, and ob- 

 tusely rounded at the tip. Last pair of epimeral plates of metasome narrowly 

 rounded at the lateral corners, posterior edge slightly convex. Eyes distinctly 

 developed, in female very small and rounded, in male (even in its not fully 

 developed state) very large, occupying nearly the whole height of the cephalon, 

 and oblong oval or reniforni, pigment dark. Superior anteniiEe in female 

 rather slender, about equalling in length the cephalon, 1st joint of the pe- 

 duncle about as long as the other 2 combined, flagellum somewhat shorter 

 than the peduncle and composed of 7 articulations, accessory appendage half 

 the length of the flagellum and 4-articulate ; those in male somewhat more 

 elongated, with a dense brush of hairs inside the 1st peduncular joint, flagel- 

 lum nearly as long as the peduncle, and provided with distinct calceolse. 

 Inferior antennae in female scarcely longer than the superior, penultimate 

 joint of the peduncle the largest, and provided at the end anteriorly with a 

 transverse series of slender spines, tiagellum about the length of the outer 2 

 joints of the peduncle combined, and composed of S articulations; those in 

 male scarcely exceeding half the length of the body, penultimate and ante 

 penultimate joints of the peduncle densely hairy in front, la si joint with : 

 calceolse in its outer part anteriorly, flagellum composed of about 20 articula- 

 tions. Gnathopoda with the hand slightly expanded in its outer part, palmar
