208 CRUSTACEA. 



Carapax not shining, neatly areolate anteriorly, posteriorly nearly 

 plane, areolet 2 M but partly divided, 3 M quite simple, 3 L, 4 L 

 separated; front emarginate, near antennae scarcely salient; antero- 

 lateral margin seven-toothed, teeth subacute and prominent, one of 

 them posterior to S. Posterior eight feet densely ciliate at margins, 

 third joint much compressed, above subacute ; hand and carpus un- 

 armed, above minutely erose. 



Plate 11, fig. 11 a, male, natural size; b, right hand, ibid.; b', fingers 

 of right hand of another specimen; c, front view of part of front, 

 showing process p, &c. ; d, part of outer maxilliped. 



Feejee Islands; Waterland Island, one of the Paumotus; also Sand- 

 wich Islands, at Oahu, Maui, and at Hilo in Hawaii. 



Length of carapax of largest specimen, nine lines; greatest breadth, 

 fourteen and a half lines; ratio of length to breadth, 1 : 1-6. 



The proportion of length to breadth is very closely the same as in 

 the midipes, and the anterior legs are similar in the pitted or irregular 

 surface. The hairy margins of the eight posterior legs at once dis- 

 tinguish it. The teeth D, E, N, T, S have the normal character, the 

 two supernumeraries are one just posterior to S, and another between 

 D and E, a little below the level of these teeth. The surface of the 

 posterior part of the carapax is very nearly even. The male abdo- 

 men is closely like that of C. nudipes ; the penult segment is very 

 slightly if at all oblong; the last segment is not oblong, and is rounded 

 at apex. The areolation of the carapax is usually very distinct, as 

 shown in the figure, though sometimes somewhat fainter. 



CHLORODIUS EXARATUS, Edwards. 

 Pacific Ocean, but particular island doubtful. 



Length of carapax, six and one-fourth lines; greatest breadth, nine 

 and one-half lines; ratio, 1 : 1-5. The species differs from the san- 

 guineus in wanting the tooth posterior to S. The areolation is similar 

 and equally distinct.
