Remarks. This genus, established by Brnzelius, is nearly allied to 

 Pardalisca, differing however in a few points rather markedly, as, for instance 

 in the mutual longitudinal relation of the 2 pairs of antennae in female, in 

 the unusually strong development of the palp of the maxillipeds, and finally, 

 by the likewise very powerfully developed gnathopoda. The genus comprises 

 as yet but a single species, to be described in the sequel.

PL IV, fig. 19. 



Body moderately slender and very tumid, subdepressed, with the back 

 broadly vaulted and quite smooth; 1st segment of urosome with 2 small, 

 juxtaposed, dorsal projections. Cephalon scarcely attaining the length of the 

 first 2 segments of mesosome combined, and rather broad, rostral projection 

 very slight, lateral corners angularly produced, their inferior edges continued 

 backwards as a laterally projecting ridge. First pair of coxal plates some- 

 what larger than the 3 succeeding pairs, which are about equal-sized and not 

 quite contiguous, all being considerably broader than they are deep, and 

 having the distal edge obliquely curved; 5th pair with the anterior lobe 

 broadly rounded, and about as deep as the preceding pair; the 2 succeeding 

 pairs very small. Last pair of epimeral plates of metasome rectangular. 

 Eyes quite rudimentary, and only visible in the living animal as a slight 

 accumulation of a yellowish pigment close to the anterior edges of the 

 cephalon. Superior antennae in female very slender and elongated, consider- 

 ably exceeding half the length of the body, 1st joint of the peduncle about 

 the length of the other 2 combined, flagellum nearly 4 times as long as the 

 peduncle, and composed of numerous articulations, the 1st of which is the 

 largest; accessory appendage comparatively small, scarcely exceeding in length 

 Vs of the peduncle, and 3-articulate, 1st articulation longer than the other 2 com- 

 bined. Same antennae in male still more elongated, and having the 1st joint of 

 the flagellum very large, and densely clothed with sensory bristles, accessory 

 appendage about the length of the peduncle, and having the 1st articulation 

 very large and lamellar. Inferior antennae in female considerably shorter 

 than the superior, last joint of the peduncle about the length of the penulti- 

 mate one, but considerably narrower, flagellum equalling the peduncle in length; 

 those in male ranch more elongated, somewhat exceeding even the superior 

 ones in length, and having the flagellum very slender, filiform. Anterior
