GRAPSOIDEA. 



tomentose lines. Abdomen of male nearly rectangular, slightly 

 narrower posteriorly, the sides subparallel and straight, last segment 

 oblong triangular, one-third as broad as penult. Sternum behind 

 the mouth pubescent. 



Plate 23, fig. 3 a, male, natural size ; b, under view, enlarged four 

 diameters; c, abdomen of male, enlarged two diameters; d, hand, 

 ibid. ; tarsus of fourth pair, enlarged. 



Valparaiso, Chili; also Sandwich Islands. 



Length of carapax of a male, 6 lines; breadth, 7'15 lines; ratio, 

 1 : 1-19 ; length of front, three lines. The outer maxillipeds are 

 pubescent, excepting the part anterior to the crest ; and posterior to 

 the mouth the sternum for a short distance is short hairy. The ptery- 

 gostome is pubescent. The orbit is like that of the integer, but the 

 tarsi are not at all spinulous ; a character, according to Edwards, of 

 that species. The general form is like that of the Audouinii, but less 

 broad for the length. The apex of the fifth joint of the posterior legs 

 is often tomentose, although that of the second pair is not so. The 

 tarsus and preceding joint have a few distant hairs below. The cha- 

 racter of the orbit separates it from either the punctatus or Audouinii. 

 It has the third joint of the outer maxillipeds much more oblong than 

 in the barbatus, as this South African species is figured by Krauss, 

 Siidaf. Crust., pi. 3, f. 3. 



The Sandwich Island specimens have similar maxillipeds, legs, 

 abdomen, and other characters.
