species, the stylocerite extending to the middle of 3rd anteuuular 

 article. 



Pleura of 6th abdominal somite immovable. Length of telson 

 equal to 4,5 times the width of posterior margin, the latter 

 presenting a trapeziforni uotch in the middle, on each side of 

 which two spiuules are inserted ; the inner longer spinule nearly 

 as long as the posterior margin is wide. 



Larger ehelipede much resembliug that of Jous. serratidigitus, 

 but the slender meropodite slightly curved, its concave lower 

 surface embracing the convex, lower surface of the palm. Palm 

 ovoid, sv^ollen, only a little longer than the fingers, the palm 

 uotched, near the carpal articulation, at the lower side, fingers 

 exactly as in Jous. serratidigüus. Second legs as in Jous. latirostris 

 Cout., but the chela twice as long as 5th carpal article. 



Relative dimensions of 3rd legs: Meropodite 1,5; carpus 1; 

 propodite 1,15. Meropodite 4,3 times as long as wide, carpus 

 5,2 times, propodite 7,7 times, the latter with 2 feeble spinules 

 on the posterior margin and a stronger one at its distal extremity ; 

 dactylus simple, slender, half as long as the propodite. 



Ova 0,63 mm. long. Length of ova-bearing female 10,5 mm. 



18. Jousseaumea hilarula, n. sp. 



Station 164. Lat. 1° 42'. 5 S., long. 130° 47'. 5 E. Depth 32 M. 



Carapace depressed. Rostrum acuminate, a little wider at its 

 base than long and reaching to the extremity of median anten- 

 nular article, with the lateral margins slightly concave; extra- 

 corneal teeth very small, acute, directed as in Jous. serratidigüus^ 

 their inner margins making a right angle with the lateral margins 

 of the rostrum. Median antennular article hardly longer than 

 thick, twice as long as the visible part of basal article and about 

 as long as the 3rd ; carpocerite as long as antennal scale, reaching 

 to the middle of 3rd article. Stylocerite a little shorter than rostrum. 



Telson as in Joics. Sibogae, n. sp., the posterior margin with 

 a small, trapeziform notch, at either side of which two spinules 

 are inserted.
