I 2 



Scaphocerite (Fig. /[d) 2,2 mm. long, two-fifths the length of the carapace," three and 

 two-thirds times as long as wide and showing the greatest width a little behind the middle; it 

 narrows rather litde distally, the outer margin is straight and the terminal spine extends be- 

 half its length beyond the rounded tip of the blade. 



External maxillipeds reaching almost to the distal extremity of the scaphocerite, very slender, 

 the length of the terminal joint is in proportion to that of the penultimate as 5 : 3, these joints 

 being respectively 1,34 mm. and 0,84 mm. long; the terminal joint is 13-times, the penultimate 

 8-times as long as wide. The exopodite extends almost to the distal extremity of the ante- 

 penultimate joint. 



Basipodite of the peraeopods of the i^' pair (Fig. 4/) with a short spine at the far end 

 of the posterior border. Merus with 4 spines on the posterior border, the i*' at the proximal 

 sixth, the 2"'^ just behind the middle, the y^ at the distal fifth and the 4'^ twice as far from 

 the 3'^ as from the distal extremity of the merus ; the 2"^ and the 3^^ spine are a little larger 

 than the two others. Carpus (Fig. 4^) about one-fourth of the merus, slightly more than twice 

 as long (0,56 mm.) than thick distally (0,26 mm.), with a short subacute tooth at the far end 

 of the posterior border. Chela a trifle longer than the merus and 4-times as long as the carpus, 

 fingers shorter than palm, proportion like 3:5; palm about 4-times as long as wide. Exopodite 

 reaching to 2°'' third of merus. 



Basipodite of the peraeopods of the 2°'^ pair (Fig. 4//) with a spine at the far end of the 

 posterior border. Posterior border of rrierus armed with 10 spines of somewhat unequal length, 

 merus one-third longer than that of the i^' pair. Carpus (Fig. 4/) one-fifth of the merus, twice 

 as long as thick, with a sharp spine at the far end of the posterior border, which spine is more 

 developed than that with which the carpus of i^' pair is armed. Chela as long as the merus, 

 almost 5-times as long as the carpus, fingers shorter than palm, proportion like 2:3; palm 

 almost 6-times as long as wide. Exopodite reaching to 2"<^ fifth of merus. 



The measurements of the legs of the 3'''^ pair (Fig. 47) are: Ischium long 0,7 mm., merus 

 1,7 mm, carpus 0,23 mm., propodus 0,94 mm., terminal joint 0,39 mm. Exopodite extending 

 almost to 2"'^ fourth of merus. Ischium of 4"> pair (Fig. 4/ — n) 0,4 mm. lonor, merus 0,26 mm., 

 carpus 0,15 mm., propodus 0,25 mm., the very short conical dactylus 0,07 mm.; a short seta 

 at the far end of the posterior border of the carpus, posterior border of propodus with 

 6 setiferous setae, a seta long 0,16 mm. at the distal end of the dactylus with a finer and 

 shorter one just near it. Exopodite just exceeding the merus. 



Ischium of s'*" pair (Fig. 40) 0,66 mm. long, merus 1,4 mm., carpus 0,46 mm., propodus 

 1, 16 mm., dactylus 0,34 mm.; dactylus (Fig. 4/) spatuliform, 0,12 mm. wide, almost 3-times 

 as long as wide and furnished with lo setae, of which the longest at the tip is distinctly 

 longer than the dactylus, while the rest gradually decrease in length. 



This form appears most closely related to the specimen from Stat. 148. Carapace and 

 abdomen, indeed, closely agree, excepting the proportion between length of carapace and 

 abdomen. The antennular peduncle reaches farther forward and the basal article is distincdy 

 longer in proportion to the two following than in the specimen from Stat. 105. The thoracic 

 legs show also different characters. In the i^' pair the carpus has a much stouter shape
