176 CRUSTACEA. 



recto, emarginato, margine anterolaterali non tenui, 5-dentato, dentibus 

 sat isolatis, vix acutis, D vix prominente, E parvulo, granuliformi. 

 Pedes antici fere cequi, manu supra rotundatd supra infraque granu- 

 losd, extus late costatd, costis granulosis, carpo granuloso, digitis cana- 

 liculatis. Pedes postici fere nudi, articulis quarto quintoque supra 

 granulosis, tar so brevissime' villoso. 



Carapax smooth, granulous near anterior and antero-lateral margins, 

 anteriorly slightly areolate, areolets 2 M, 3 M behind usually hardly 

 circumscribed, 4 L, 5 L, G L coalescent and posteriorly not circum- 

 scribed; front nearly straight, emarginate, antero-lateral margin not 

 thin, 5-dentate, teeth rather separate, hardly acute, D scarcely pro- 

 minent, E small, granuliform. Anterior feet nearly equal, hand 

 rounded above, above and below granulous, outer surface with a 

 few wide granulous costse, carpus granulous, fingers channeled. 

 Posterior feet nearly naked, fourth and fifth joints granulous above, 

 tarsus very short villous.

Tutuila and Upolu, Samoan Islands; also probably from the So- 

 ciety, or Paumotu Islands. 



Length of carapax of a female, four and one-fourth lines; breadth, 

 six and one-fourth lines; ratio of length to breadth, 1 : 1-47; in ano- 

 ther specimen, a male, length, two and three-fourths lines; breadth, 

 four and one-tenth lines; ratio, 1 : l - 49. Colour (believed to be of this 

 species), irregularly blotched and spotted with brown on a grayish or 

 yellowish white base. Anterior legs yellowish white, fingers brownish 

 black. The hand is granulous below as well as above, and the coslse 

 of the outer surface, instead of being single rows of granules, are low 

 longitudinal ridges closely covered with granules. The teeth of the 

 antero-lateral margin are not properly acute. The absent one of the 

 normal teeth is E. The outer angle of the orbit is not at all elevated, 

 the thin rim of the orbit being evenly continuous around the other 

 side. The carpus has an indentation on the outer surface, a short 

 distance from the anterior margin. The orbit is very nearly circular 

 with an entire (or nearly entire) and even margin.
