 a half as long as the peduncle, 3rd joint of the peduncle once 

 and a half as long as the 2nd. Ischium of external maxillipedes 

 very little longer than broad, merus as broad as long, propodite 

 strongly expanded, lamellar, just as broad as the merus. 



Legs of Ist pair as in Call. mucronata, but the ischium is armed 

 in both with 7 or 8 spines on its lower margin. Palm of larger 

 chelipede once and a half as long as the carpus, carpus barely 

 broader than long. Propodite of 3rd legs with obtuse lobe on hinder

Station 5. Lat. 7° 46' S., long. 114° 30'.5 E. Depth 330 M. 



Carapace comparatively large, little less than half the length

 long, with obtuse, rounded apex ; exopodite a little more than 

 half as broad as long, rounded apically, antero- external angle
