 in shape nearly like a V reversed. 



XANTHODES NOTATUS.

Carapax anteriorly neat areolate, the areolets flat with abrupt sulci 

 between and surface nearly smooth or very minutely erose; front 

 nearly straight, emarginate, antero-lateral margin five-toothed, tooth 

 D, nearly obsolete, E, N, tuberculiform, T, S, acute spiniform. An- 

 terior feet quite unequal, larger hand and carpus small tuberculate, 

 hand smooth above, shining, smaller hand and carpus densely 

 armed with spines. Eight posterior legs hirsute, third joint above 

 denticulate.

 as seen in a front view, with part of base of outer antennae. 



Paumotu or Society Islands ; also Sandwich Islands. 



Length of carapax of female (with eggs) , three and two-thirds lines ; 

 greatest breadth, five and a half lines ; ratio of length to breadth, 

 1 : 1'5. The sulci are abrupt and the areolation neat and complete, 

 excepting posteriorly. 3 M is very distinct ; but 4 M is very narrow 

 and indistinct. In a Sandwich Island specimen (a female), the left 

 hand is very much the larger, and the reverse is true of the other 

 specimen from south of the equator, which also is a female. The 

 moveable finger of the large hand is not channeled. The posterior or 

 outer surface of the fifth pair of legs is smooth and naked, while the 

 margin is denticulate and towards apex hirsute. The following joints 

 are hirsute throughout.
