AMl-mi'ODA — STEBBING. G07 



male about lialf as long as the second, with flagellum of nine 

 joints ; in the other specimen the third joint is scarcely more 

 than a third of the second, with flagellum of six joints. The 

 accessory flagellum is microscopic, a tubercle tipped with several 

 setules. The second antennse have the gland-cone acute, the 

 third joint stout, the fourth stouter and a little longer than the 

 fifth, which a little exceeds the four-jointed flagellum, armed on 

 each of these joints with a pair of curved spines. 



The lower lip has a peculiar appearance by the wide display 

 of the inner lobes between the rather narrow principal lobes. 

 The mandibular processes are narrow, curved. 



The mandibles have the cutting edge and accessory plate not 

 much divided, the latter less strong on one mandible than on the 

 other; spine-row of three or four spines; molar strong; curved 

 .second joint of palp about twice as long as first, with a single 

 spine on the margin ; third joint as long as first and second 

 united. 



First maxillte with inner plate seemingly unarmed, outer plate 

 with short spines, second joint of palp elongate. Second maxillsfr 

 with inner margin of inner plate fringed. Maxillipeds with three 

 spine-teeth on truncate distal margin of inner plate ; outer plate 

 reaching end of second joint of palp, its inner margin fringed with 

 eight spine-teeth, followed by some graduated spines on distal 

 border. 



First gnathopods of adult male with fifth and sixth joints 

 robust, subequal in breadth and length, the sixth having a palmar 

 spine at apex of hind margin, flanked by a conical tooth from the 

 base of which the palm slopes to the broadly truncate hinge 

 margin carrying the curved finger. Inner margin of finger with 

 small decurrent tooth, its apex with small unguis. The 

 (supposed) female has the side-plate much more narrowly produced 

 forward, the fifth and sixth joints of the limb narrow, the fifth 

 rather the longer, in the sixth joint the short piece between the 

 palmar spine and the hinge margin almost continuous with the 

 hind margin. The setose furniture of the gnathopods of both 

 pairs in both (presumed) sexes is alike. 



Second gnathopods of adult male with fifth joint longer than 

 sixth, both less broad than those of the first pair, but subequal 

 in combined length, short palm of sixth joint curving over to 

 hinge margin. In the (supposed) female these two joints are 

 much narrower than those of the male and are also narrower than 

 those of their own first gnathopods. 



The first and second peraeopods are alike, the fifth joint 

 narrower than the fourth, the sixth than the fifth, the finger 

 nearly straight. The hind margin of the sixth is armed with four
