CANCROIDEA. Igg 



finger spinulous above. Following feet compressed, surface with a 

 hardly distinguishable pubescence, and margins set with rather stiff 

 hairs. 



Plate 9, iig. 4 a, female, enlarged two diameters ; b, front view of 

 front; c, right hand; d, female abdomen, enlarged two diameters. 



Wakes Island, Pacific Ocean. 



Length of carapax, ten lines ; greatest breadth, fourteen lines ; ratio 

 of length to breadth, 1 : 1*4. 



The areolets are all very prominent, and rounded above, with the 

 surface, as seen under a magnifier, dotted with a few rounded gra- 

 nules or minute tubercles, which on areolet 1 P form the whole surface. 

 Besides these there are more minute black dots, which appear to be 

 minute hairs like those that form the exceedingly short pubescence of 

 the legs. The acute points on the outer surface of the hand are in 

 four or five series, but above they are more scattered. Areolet 1 P has 

 a pointed prominence at middle of posterior side, and an emargination 

 corresponding on the anterior margin. The fissure in the inner angle 

 of the orbit is exceedingly small, and the antennary process filling it 

 is short. The margin of the front just inside of the antennae does not 

 project, but it is continued downward with a nearly vertical surface. 



The abdomen has a pubescent surface and ciliate edge. 



Genus ZOZYMUS, Leach. 



Carapax undique convexus, margine antero-laterali tenui, cum angulo 

 post-orbitali coalito. Pedes 8 postici valde compres&i, articulis acie 

 acutd supra iristructis. Habitu Atergati Actaesegwe affinis, 



Carapax convex in every direction ; antero-lateral margin thin and ter- 

 minating anteriorly in the outer angle of the orbit. Eight posterior 

 feet much compressed, joints thin and having an acute edge above. 

 In habit, resembling Atergatis and Actaea. 



The type of Zozymus of Leach, as well as jEgle of De Haan, is the 

 Zozymus ameus, in which the legs are cristate ; and the genus is here
