 2 M non omnino divisd, 3L, 4:L sejunctis, 1 P, 2 P coalitis aut vix 

 sejunctis, fronte emarginato, juxta antennas saliente, margine antero- 

 laterali 10-11-denticulato, uno dente pone & Pedes toti nudi ; an-

 acuto. 



Carapax not sliming, anteriorly neatly areolate, posteriorly nearly 

 plane, areolet 2 M not divided through, 3 L, 4 L separate, 1 P, 2 P 

 united or but faintly separate; front emarginate, near antennae 

 salient; antero-lateral margin 10-11-toothed, one tooth being poste- 

 rior to S. Feet all naked, anterior pair stout, hand and carpus 

 unarmed, surface finely erose above, carpus armed within with a 

 short spine. Eight posterior feet rather short, third joint not having 

 a sharp upper edge.

Length of carapax, four and one-half lines ; greatest breadth, seven 

 and one-fourth lines; ratio of length to breadth, 1 : 1*6. Like the 

 preceding species, the carapax is not shining. It differs from them in 

 having the posterior surface but very slightly depressed transversely 

 between areas 1 P and 2 P. It is peculiar in having naked legs and 

 an unusual number of teeth on the antero-lateral margin. The sur- 

 face of the carapax is somewhat pitted as seen under a microscope, 

 and the carpus and hand are decidedly pitted or erose, or a little 

 uneven : in this last point it resembles the following species. The ten 

 or eleven teeth of the antero-lateral margin are divided as follows : 

 one corresponds to D, two to E, three to N, two or three to T, and 

 two to S, the second of S being a posterior tooth, and sometimes 

 having another smaller behind it. Of the three to N and T, the 

 middle one is the largest. The penult segment of the male abdomen
