-2 CRUSTACEA MALACOSTRACA. II. 



AntennulEe slightly longer than the carapace. First joint is even more than half as long again 

 as the two other joints combined, seen from the side (fig. 5 c) almost four times as long as deep and 

 tapering much from near the base to the end; seen from above (fig. 5b) this joint is somewhat less 

 than three times as long as broad and the distal half is much narrower than the proximal, which 

 has the outer margin a little angular somewhat from the base and the limit between the proximal 

 and the distal part incised and furnished with an outstanding seta. Second joint is, seen from the 

 side, more than twice as long as deep; third joint is somewhat less than twice as long as the second, 

 and its longest terminal setae about as long as the first joint. — Antenna; (fig. 5c) of normal length; 

 third joint is distinctly thickened, fourth joint slightly more than twice as long as the penultimate; 

 terminal setae only a little shorter than those of the antennulse. 



Chelipeds (fig. 5e) moderately stout. Basal joint somewhat long, with the posterior protuberance 

 of middle length, rounded behind and reaching to near the front margin of second segment; carpus 

 considerably longer than the basal joint and somewhat less than three times as long as deep. Chela 

 slightly longer than the carpus, about three and a half times as long as broad and with the posterior 

 margin considerably concave; movable finger as long as the anterior margin of the hand and a little 

 narrower than the fixed finger. 



Thoracic segments (fig. 5 a) show a little difference in breadth. Second segment somewhat 

 more than half as long as the third, anteriorly as broad as, or a little narrower than, the carapace, 

 with the lateral margins somewhat converging to the posterior margin and below a moderately small 

 ventral process curved forwards and originating near the front end. Third, fourth and sixth segments 

 with their lateral margins nearly parallel and the corners rectangular; fifth and sixth segments witli 

 the lateral margins diverging a little from the anterior to the posterior end; third segment slightly 

 shorter than the fourth, which is as long as the sixth, a little shorter than the fifth and half as broad 

 again as long. — Thoracic legs of moderate length and thickness. Second pair (fig. 5e) with some- 

 what short setae; sixth joint long, even a little longer than fifth plus half of the fourth; seventh joint 

 with claw slightly longer than fifth joint. Third pair with fourth to sixth joint conspicuously shorter 

 than in second pair; sixth joint only a little shorter than fourth and fifth joints combined, twice or 

 more than twice as long as seventh joint with claw; setae somewhat short. Three posterior pairs 

 nearly as in T. iinrquipes (comp. fig. 9 a); second joint about two and a half times as long as broad; 

 fourth joint with a minute tooth; fifth joint a little expanded; sixth joint somewhat slender and almost 

 as long as the two preceding joints combined; seventh joint with claw of middle length. 



Abdomen not broader than the posterior part of the thorax but somewhat longer than its two 

 posterior segments combined. — Uropods short (fig. 5d); endopod two-jointed, with the proximal joint 

 a little longer than the distal; the exopod reaches beyond the middle of second joint of the endopod 

 and seems to be one-jointed. 



Length of the largest specimen 1.76""". 



Subadult Male (fig. 5e). Antennulae about as long as the carapace and half of the next 

 segment combined, thick; first joint somewhat longer than the two other joints combined, seen from 

 the .side .somewhat le.ss tlian three times as long as deep and slightly tapering towards the end;
