DISCOVERY REPORTS 



Chelophore long and slender. ^ Scape distinctly two-jointed, the first nearly twice as 

 long as the second segment. Chela small; fingers longer than palm, gaping when 

 closed (Fig. 45 o). 



Palp an elongated papilla between base of chelophore and oviger. 



Oviger already ten-jointed, although segments 9 and 10 are not completely separated 

 off from each other; reaching to tip of proboscis when straightened out. The right 

 oviger is bifurcated near the tip (Fig. ']\c). 



Third leg long and slender. Second coxa half as long again as the sum of the first and 

 third. Second tibia shorter than either of the two preceding segments; first tibia the 

 longest segment. Tarsus very short, propodus with two prominent spines proximally 

 on the ventral margin. Claw long, auxiliaries absent (Fig. 45 b). There are no setae on 

 the trunk and only a few spinose setae near the distal end of the leg.

Remarks. This specimen is not quite mature, no genital pores can be distinguished. 

 It appears to belong to the genus Pallenopsis, but does not belong to any of the species 

 previously recorded from South African waters. There can be no doubt that the species 

 is pelagic, for the total depth at the locality in which this specimen was obtained exceeds 

 4000 m." No pelagic species of Pallenopsis appears to have been previously described, 

 but Flynn (1928, p. 25) has described a pelagic species of Anoplodactyliis from off 

 Port Natal. 



The specimen probably belongs to a small species characterized by (i) the almost 

 complete absence of setae, (2) the complete suppression of the auxiliary claws on the 

 legs, and (3) the presence of but one pair of eyes.

^ Length of scape eight to nine times the distal width. 



^ The specimen could not have got into the net from dredged material obtained elsewhere: for nearly 

 two months prior to its capture plankton nets only were in use.
