Family VI. CHONDEACANTHID^. 



Female forms incompletely or indistinctly segmented, often of 

 particularly bizarre appearance from the growth of irregular lobes 

 and prolongations. The anterior antennse are short, 2-3-ioiuted, 

 the posterior generally in the form of simple hooks, often 

 powerful. Maxillipeds small, unciform, close to the mouth-opening ; 

 limbs generally in the form of non-articulate lobes. Sex-organs 

 paired, often very voluminous. External ovaries claviform ; ovules 

 mulliseriate in most cases, sometimes convoluted or hidden. 



The pigmy male is out of all proportion to the female, to which 

 it is firmly adherent. It has a distinct cephalothorax, segmented 

 abdomen, and is furnished with articulate limbs. 



G. 1. Sphyeion Cuv. {Lesteira Kr.) 



Plead float-like, enlarged transversely, separated by a long 

 cylindrical neck from the genital segment, which is cordiform 

 or oval, flattened antero- posteriorly ; this gives off on either side 

 of the rudimentary abdomen a bunch of hard grape-like processes 

 projecting backwards. Thoracic limbs suppressed. Egg-tubes 

 long, robust. Antennae as non-articulate lobes.
