of 4 setae. Endopodite 1-segmented, styliform, larger than exopodite, 

 with total of 6 setae, 4 of which occur at apex. 



I failed to obtain a satisfactory preparation of the maxillule. 



Maxilla (fig. 114c) with swollen praecoxa with 2 endites, bearing 2 

 and 1 seta respectively; swelling externally haired. Coxa with 2 

 endites, each with 2 setae. Basis composed of 2 segments: segment 1 

 with endite, carrying strong, curved spine and seta; segment 2 with 

 scarcely visible endite, pressed against endite on segment 1, with 

 single seta. Endopodite with total of 3 setae, 2-segmented. 



Maxillipede (fig. 1 14c^) chelate, coxa with 2 haired setae near jointing 

 with basis. Basis scarcely swollen, with internal row of hairs. Endop- 

 odite unsegmented, forming curved digit, as long as basis, and with 

 additional seta. 



Legs 1 to 4 (figs. 113a-d) with 2-segmented endopodites and 3-seg- 

 mented exopodites; the setal formula is: 



endopodite exopodite 



leg 1 1. 020 0. 0. 022 



leg 2 0. 021 1. 0. 122 



leg 3 1. 021 1. 0. 222 



leg 4 1. 021 1. 1. 222 



Leg 1 (fig. 113a) with external seta and internal spine on basis. 

 1st endopodal segment styliform, 6 times as long as broad, internal 

 seta strongly haired. 2nd endopodal segment twice as long as broad, 

 with 2 apical setae. 



Legs 2 to 4 with strong spine on basis between insertion of 

 endopodite and exopodite. External seta on basis fine; legs 2 and 3 

 with basis at internal margin produced to form spine. Legs 2 and 3 

 normally developed and, except for small differences in setation, very 

 much alike. Leg 4 with greatly lengthened exopodite and short 

 endopodite; especially 1st endopodal segment very short. All 3 

 exopodal segments lengthened, segments 1 and 2 with very small 

 external spine; segment 3 with 2 very small external marginal spines. 

 All setae of segment 3 concentrated on apical portion. 



5th legs of both sides greatly developed, strongly curved, forming 

 incubatory pouch containing (in this specimen) 6 big eggs. Exopodite 

 and baso-endopodite of each side fused, forming hollowed spoon-shaped 

 structure, both sides touching but not actually fused. External lobe 

 visible and with fine seta. The shape of each leg can best be judged 

 from figure 113e, but it should be remembered that the outline, as 

 represented in the drawing, is influenced by pressure of the cover glass 

 on this hollow structure. External margin with 3 fine setae, margin 

 terminating in spine. 2 more setae at caudal border and small, 

 haired seta near end of internal border. 



Color faded, yellowish, more or less transparent. No eye or 

 pigmented spot visible.
