along its whole length, by a furrow near and parallel with the upper border and another rnns 

 near the lower, but reaches only a little beyond the middle. A shallow groove occurs on the 

 outer side of the carpus near its rounded, upper border. The compressed propodus is one and 

 a half as long as the carpus and somewhat more than twice as long as broad ; in the largest 

 specimen (c?) from Stat. 5 1 the carpus is 2 1 /. mm., the propodus 3 mm. and the dactylus 

 2 1 /.. mm. long, the propodus is i 1 /. mm. broad. The propodus, that presents its greatest width 

 in the middle, narrows somewhat towards the distal end; its slightly curved, upper border is 

 fringed with short hairs on the inner side, its lower border is straight. The outer surface of 

 the propodus carries two deep grooves, respectively near and parallel with the upper and 

 the lower margin ; neither of them reaches the distal extremity and the lower groove is a little 

 shorter than the other. The merus of the 3 rd legs, (PI. II, fig. ioc), which is a little longer but 

 less broad than that of the 2 nd pair, is traversed on its outer surface only by one furrow, 

 namely that near the upper border. The three following joints resemble those of the 2 nd pair, 

 but the compressed propodus is a little broader in proportion to its length : the carpus is 

 2 1 / 3 mm., the propodus 3 mm. and the dactylus 2 1 /. mm. long, while the propodus is i 3 /- mm. 

 broad. The two furrows on the outer side are equally long and extend almost to the distal 

 end. The 4 th and the 5" 1 pair of legs have a quite different appearance, because their propodi 

 are considerably longer and slenderer. The legs of the 4" 1 pair (PI. II, fig. ïod) reach 

 as far forward as the anterior tooth on the outer margin of the proximal antennal squame, 

 those of the last pair as far as the antero-lateral angles of the carapace; both pairs of legs 

 are traversed on the outer surface of their joints by a longitudinal furrow. 



The i st abdominal somite is destitute of appendages, both in the male and in the female. 

 Those ot the 4 following somites agree substantially with those of Scyll. cultrifer (Ortm.) = 

 sordidits (Sp. Bate) and with those of Scyll . oricntalis (Sp. Bate). In the male the pleopods of 

 the 2 nd somite are biramous, the two branches falcate-foliaceous, somewhat unequal in length 

 and breadth ; of those of the three following somites one branch is foliaceous, the other is a 

 rudimentary process. In the female the appendages of the 2 nd somite are biramous, the two 

 branches broadly-foliaceous and the endopodite, which is little less broad than the outer plate, 

 carries a styliform, internal appendix, 0,5 mm. long, furnished with a few setae at the distal 

 end, but destitute of cincinnuli; those of the three following pairs are biramous, one branch 

 foliaceous, spathulate, fringed with plumose hairs, the other slender, 3-jointed and supplied with 

 long plain setae. 



The carapace of the largest specimen, a male from Stat. 51, is 1 1 1 ^ mm. long, measured 

 in the middle line and without the antennular somite, the abdomen is 23 mm. long, the distance 

 between the antero-external angles of the carapace i2 8 / 4 mm. broad, the whole length from the 

 anterior margin of the distal squame of the outer antennae to the end of the telson 40 mm. 

 In younger specimens the distance between the antero-external angles does also slightly surpass 

 the length of the carapace, measured in the middle, so e. g. the carapace of another specimen 

 is 11 mm. long, that distance, however, 11,5 mm. The carapace of the female from Stat. 51 

 is 10,7 mm. long, the abdomen 19 mm., the distance between the antero-external angles 11,2 

 mm., the whole length, the outer antennae included, 36 mm.
