184 CRUSTACEA. 



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

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

 outline. The antero-lateral margin has the five teeth D, E, N, T, S, 

 and in the E. 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 Actaeodes. This second group may be named ETISODES. 



ETISUS DEFLEXUS. 



Carapax leviter bene areolatv.s, Icevis, fronte inter-antennali k-lobato, tenui, 

 valde dejiexo, setigero; margine antero-laterali 5-dentato, dentibus sub- 

 acutis, secundo minore. Pedes antici sat longi, manu carpoque extus 

 supra que bene yranulosis, diyitis Icevibus; reliqui angusti, valde pilosi. 

 Abdomen maris 5-articulatwn, eoque levimani 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.
