are not longer than, and are often shorter than, the postero-lateral. 

 The basal antennal joint does not touch, or only just touches, the 

 front. 



Alliance I. Pilumnoida. Carapace commonly densely tomentose, 

 its regions commonly well defined and areolated. 



Alliance IT. Heteropanopioida. Carapace smooth, its regions 

 either not at all, or not very well defined. 



Sub-family VII. Eriphiinj:. 



Carapace sub-quadrilateral, the an tero- lateral borders not forming 

 an arch but meeting the postero-lateral borders at a very open and 

 inconspicuous angle. Front very broad, half or more the greatest 

 width of the carapace, and, with the orbits, occupying the whole anterior 

 border of the carapace. Basal antennal joint not touchiug the front. 

 Abdomen of the male either with all 7 segments distinct or with the 

 3rd, 4th and 5th fused. 



Alliance I. Eriphioida. The gastric region, at least, is well 

 defined : basal antennal joint short and thick : orbits deep : arms stout 

 and short. 



Alliance II. Trapezioida. Carapace perfectly smooth, without 

 trace of regions : basal antennal joint slender : orbits shallow, affording 

 little concealment to the eyes : arms long or very long, projecting in 

 large part or entirely beyond the carapace, in repose. 



Alliance III. Domecioida. No trace of regions; orbits shallow; 

 arms short ; legs, chelipeds, and frontal and antero-lateral borders of 

 carapace strongly spinate. Merus of external maxillipeds more than 

 twice as broad as long. 



Alliance IV. Melioida. Carapace hexagonal, the regions either 

 absent or fairly well defined ; basal antennal joint slender ; orbits 

 shallow. The chelipeds are very much shorter and slenderer than the 

 legs. 



Subfamily IV. Menippinje. 



Alliance I. Menippioida.
