ANOMOURA PORCELLANIDEA. 4^3 



A small and very convex species, slightly broader than long. The 

 hand is broad and short and has faint longitudinal sulci, with a slight 

 rugosity. The fingers are widely gaping in our specimen. The 

 carpus is slightly longer than broad, three-toothed within, the first 

 tooth much the largest, and its surface is nearly smooth. Following 

 legs very nearly naked.

Body rather thick. Carapax smooth, hardly broader than long, front 

 obsoletely triangulate, pubescent above. Carpus broad, not oblong, 

 anterior margin three-toothed, upper surface with four crowded 

 rows of tubercles looking like beads j hand broad and short, also 

 seriately tuberculous. Following feet narrow, hirsute above.

Length of carapax, 4*3 lines; breadth, 4 '4 lines; length of carpus 

 of larger leg, 3 lines, and breadth, 31 lines, being broader than long. 

 The proportions of the animal are nearly as in the grossimana. It is 

 also near the sculpta; but the front is not straight transverse, and the 

 anterior margin of the arm is three-toothed. These teeth are nearly 

 equal (the basal longest), sparingly denticulate and minute tubercu- 

 late above. The tubercles of the carpus and hand look somewhat 

 like ranges of beads. The moveable finger is also tuberculate; surface 

 of hand under base of moveable finger densely hairy. The fourth and 

 fifth joints of the fourth pair of legs are densely hirsute above ; the
