dente acuta instructs, superficie inter has angulos paulo carinaid, 

 fronte undulato, paulo injkxo. Carpus leviter granulans, mtus in, 

 cequaliter 4 dentatus, extus versus apicem 2-3 serratus ; manus minute 

 granulata, nuda. Articulus pedis ill 6tus gracilis, paulo compressus, 

 sparsim pubescens. 



Carapax depressed, smooth, sparingly oblong, a short distance behind 

 the orbit an acute tooth, surface between the post-orbital angles 

 somewhat carinate either side of the medial line ; front undulate, 

 inflexed. Carpus fine granulous, on inner margin about four un- 

 equal teeth, on the outer towards apex two or three serratures. 

 Hand minute granulous, naked. Fifth joint of fourth pair of feet

Length of carapax, 4 '4 lines; breadth, 4 lines. Colour, yellowish 

 or buff, with purple and orange dots; legs of same colour, excepting 

 third and fourth joints of second, third, and fourth pairs, which are 

 purple with some buff, and white on outer half of lif'tb joint. The 

 carapax is slightly' granulous or rugulose near the lateral margin. 

 The outer margin of the carpus is somewhat raised and granulato-serru- 

 late, becoming serrulate near apex. There are sometimes live teeth 

 on the inner margin of the carpus, though usually but four. The 

 beak is rounded at extremity, and the apical portion is flexed down- 

 ward a little more than the preceding part. 



This species has the tooth behind the orbital angle which charac- 

 terizes the maculcda, but it is not '"bombee;" the beak is not nearly 

 horizontal, and the carpus has four instead of two or three teeth on 

 the inner margin. The third joint of the fourth pair oi' legs is twice 

 as broad as the fifth joint. The hands are granulous on both surfaces. 

 The outer antenna? are about three times as long as the carapax.
