CANCROIDEA. 193 



The species referred to this genus would fall in with Liomera, 

 were it not for the form of the fingers, in which respect they are 

 like the Zozymi. Xantho obtusus of De Haan, pi. 13, f. 5, appears to 

 be included. 



CARPILODES TRISTIS. 



Carapax latior, latd subrhombicus, Icevis, non nitidus, anticd sat areo- 

 latus, areolis 1 M 2 M conjunctis, 2 L 3 L conjunctis, 4 Z< 5L QL con- 

 junctis ; f route brevi,fere recto, levissime emarginato ; margine antero- 

 laterali A-lobato, lobis rotundatis ; later e postero-laterali recto, convexo. 

 Rdes antici cequi, breves et parvi, nudi et inermes, lames. Pedes postici 

 vix compressi, nudi. 



Carapax broad subrhombic, smooth, not shining, somewhat areolate 

 anteriorly, areolets 1 M and 2 M united, so also 2 L and 3 L, and also 

 4 L, 5 L, 6 L ; front short, almost straight, very slightly emarginate, 

 antero-lateral margin four-lobed, lobes rounded ; postero-lateral side 

 straight, convex. Anterior feet equal, short and small, naked and 

 unarmed, smooth. Posterior feet hardly at all compressed, naked.

Paumotu Archipelago? 



Length of carapax, 6 '15 lines; greatest breadth, 10'5 lines; ratio of 

 length to breadth, 1 : 1-7. The surface has a smooth, dull look, and 

 the furrows though neat are not deep. The fingers are channeled, 

 and the hand is seen to have the outer surface a little uneven when 

 magnified. The antero-lateral sides are nearly parallel to the diago- 

 nally opposite postero-lateral, and this gives an approach to a rhombic 

 form to the outline. The base of the outer antennae is continued to 

 the same height as the outline of the orbit.
