fully grown. The front is four-lobed, the two outer lobes adjoining 

 the eves short, the two inner long and either straight or arcuate in 

 outline. The 'anterolateral margin has the five teeth D, E, N, T, S, 

 and in the K levimanus, one or more smaller teeth appear between N 



and T, and T and S. 



The genus includes two groups — one having the arm long and 

 much exsert beyond the carapax, the carapax quite broad and not 

 deeply areolate; — the other with the arm short and little exsert, if at 

 all, the carapax narrow, and in these and other characters approach- 

 ing Acta3odes. This second group may be named Etisodes. 



Etisus deflexus. 



Carapax levitcr bene areolatus, lewis, fronts inter-antmnali i-lobato, ienui, 

 valde defiexo, setlgero ; margine anterohtterali 5-dentato, dentibus sub* 

 acutis, semndo mlnore. Pedes antiei sat longi, manu carpotflte extus 

 supraque bene granulosis, digitts Icevibus; reliqni angusti, valde pdosi. 

 Abdomen maris b-articidatum, eoque leviinuni simile. 



Carapax distinctly but lightly areolate, smooth, front between outer 

 antennae four-lobed, thin, much deflexed, setigerous, antero-lateral 

 margin five-toothed, teeth subacute, second smaller than the others. 

 Anterior feet rather long, hand and carpus with the outer and 

 upper surface neatly granulous, fingers smooth; following feet nar-

 levimanus.
