Bfiiiarks. — The type of this genus is the form described by Sp. 

 Bate and Westwood under the uame of O^j/.v (iradritMUHi. which however 

 show's only a very remote affinity to the Kroyerian genus (Jpis, wherefore 

 Boeck saw himself fit to establish for it a new genus under the above name. 

 Its distinctive characters are among others the peculiar structure of the 

 anterior gnathopoda, which somewhat resembles that iu the youug of Trischi- 

 zo^tonui, the imperfect development of the pal]) of the maxillipeds, and the 

 structure of the last pair of uropoda and of the telson.

Body somewdiat compressed, with the back evenly vaulted. Cephalon 

 rather deep and nearly as long as the 2 anterior segments of the mesosome 

 combined, lateral corners only sliglitly jirojecting Ijut distinctly angular. The 

 3 ])asterior segments of the mesosome much larger than the 4 anterior ones- 

 Coxal plates scarcely deeper than the body, rounded inferiorl}' ; 5th iiarr con-

 Lateral corners of the ord pair of ejiimeral ])hites of the metasome evenly 

 rounded. Fir.st segment of urosome not ]iroduccd dorsally. Eyes large, oval 

 in form. Superior antennae about the length of the cephalon and the 2 ante- 

 rior segments of the mesosome combined, 1st joint of the peduncle not twice 

 the length of the other 2 taken together, Hagellum composed of 5 joints onh^ 

 accessory appendage very slender, triarticulate. Inferior antennae ^in female) 

 about the length of the superior, Hagidluni 4-articulatc. Anterior gnathopoda
