Subfamily II. ACTAEIN^E. 



Carapace usually much broader than long and usually very pro- 

 fusely nnd profoundly lobulated ; the antero-lateral border is either 

 divided into 4 blunt lobes, or crenated. The front is about a third the 

 greatest breadth of the carapace, sometimes a little more, sometimes a 

 little less, and is divided into two rather prominent usually round- 

 pointed lobes. 



Subfamily III. CHLORODIN^l. 



Carapace hexagonal or transversely oval, or subcircular (Cynio) or 

 approaching the subcircular (Cyclodius). Front from a third to half 

 the greatest breadth of the carapace — much broader than in the preced- 

 ing subfamilies. 



Alliance I. Xanthodeoida. Carapace transversely oval, front a 

 third or little less than a third the greatest breadth of the carapace, 

 fingers not hollowed at tip. 



Alliance II. Chloeodioida. Carapace transversely oval, front 

 nearer half than a third the greatest breadth of the carapace, fingers 

 hollowed at tip. 



Alliance III. Ctmoida. Carapace subcircular, flat ; front about 

 half the greatest breadth of the carapace : chelipeds remarkably un- 

 equal.
