Carapax [anteriorly strong areolate, areolets all distinct, surface mi- 

 nutely punctate, 1 M and 2 M partly coalescent, 2 M not subdivided ; 

 front somewhat produced, emarginate, lobes with the margins con- 

 cave; antero-lateral margin rather stout, 6-7-toothed, the teeth 

 being D, d', E, N, T, S, s', D but slightly projecting, d' smallest, 

 E, N, T, S, subconical, obtuse. Anterior feet unequal, unarmed, 

 hand and carpus minutely corrugate or areolate, moveable finger 

 not channeled, apex stout obtuse and but little excavated within, 

 and having no large basal tooth. Eight posterior feet nearly naked, 

 tarsus naked above, somewhat hirsute below. 



Plate 11, fig. 14 a, male, natural size; b, front view of front, show- 

 ing base of outer antennae ; c, outer maxilliped, enlarged two dia- 

 meters; d, right hand, natural size; e, surface of carapax, enlarged; 

 f another portion of carapax ; g, part of branch of first maxillipeds. 



Sandwich Islands. 



Length of carapax of a male, ten and a half lines; breadth, seventeen 

 lines; ratio of length to breadth, 1:1-62. The species resembles 

 closely the C. sanguineus in form, areolation, teeth, and the uneven 

 surface of the hand and carpus. But the eight posterior legs are 

 nearly naked, the anterior margin of the third joint quite so; the 

 tarsus is naked on its upper margin; moreover, the surface of the 

 carapax is fine punctate. The areolet 2 M has on the front of the 

 outer half a V-shape depression. The tooth D is obsolete ; the orbit 

 has a small tooth-like prominence just below D, which is more promi- 

 nent. The third joint of the outer maxillipeds has a small emargi- 

 nation on the anterior margin near the inner apical angle, and this 

 margin is pubescent; the surface of this joint, moreover, is granulous 

 and uneven. 



The extremity of each finger is rather small and rounded, and 

 there is but a slight spoon-shape excavation, the edge being thick,
