The external maxillipeds are slender and pediform, with the 2nd joint 

 (basis-jschium-merus) slightly arched outwards, and with a flagelliform exopodite 

 Imt no epipodite. 



The exopodites of the thoracic legs are well-developed, but only in the 

 case of the reduced 4th pair do they approach anywhere near to the length of 

 the endopodites. 



The first two pairs of thoracic legs are far longer and stouter than any of 

 the others : they end in longish chela?, which have longer slender hooked-fingers 

 with very elegantly and evenly pectinate teeth. 



The 3rd, 4th and 5th pairs are slender (especially the 3rd pair) and short, 

 the 4th pair being about half the length of the other two. 



The abdominal appendages are biraraous and narrowly foliaceous, the exo- 

 podites being of ordinary length and (except in the case of the 1st pair) not 

 twice as long as the endopodites : all behind the 1st pair have the usual styli- 

 form appendix at the inner edge of the endopodite. 



The eggs though fairly numerous are large. 



The branchial formula is as follows : —
