PORCELLANIDEA. 



ANOMOURA 



duobus minutis dentibus acutis armafo, et anterius 23-denticulato, 

 latere carapacis prope medium tri-spinuloso, pone angulum post-orbi- 

 talem dente acuto, et posterius in superfine carapacis altero simili. 

 Pedes antici mediocres, rugati et scabriculi, carpo elongate, intus k-den- 

 tato dentibus fere cequis, extas juxta marginem spinulis seriatis ornato, 

 manu tenui, ad marginem externum hirsutd. Pedes sequenles sparsim 

 criniti, articulo tertio supra 3-4 spinuloso. 



Carapax much depressed, sparingly oblong, transversely faint rugate, 

 and in part minute hirsute; front prominently and broadly trian- 

 gular, above the eyes a small acute tooth, and another just anterior 

 to this, and still more anterior two or three denticulations ; sides of 

 carapax near middle with three spines, behind the post-orbital 

 angle an acute tooth or spine, and another posterior to this on the 

 surface of the carapax. Anterior feet of moderate size, rugate and 

 somewhat scabrous, carpus oblong, having four acute, nearly equal 

 teeth within, and on upper surface near outer margin a series of 

 spines; hand thin, at outer margin hirsute. Following pairs of 

 feet sparsely hairy, third joint with three or four spinules on the 

 upper margin.

Length of carapax, 2-4 lines; breadth, 2'1 lines. The beak is with- 

 out lateral lobes, the triangle occupying the whole breadth ; yet there 

 are two teeth near either eye, which place the species near the spini- 

 frons, although the spines are smaller than in that species. The 

 lateral spines are in all five on either side, posterior to the post-orbital 

 angle; \hefirst is situated just behind the antero-lateral emargination, 

 and not anterior to it ; the second is behind the first, a little distance 

 from the margin ; the other three are marginal, or nearly so. The 

 teeth of the arm are nearly as broad as long, and acute. The upper 

 surface of the hand has the upper and lower parts of the outer surface 

 meeting in an angle, along a line reaching from the base to the arti- 

 culation, and either part is rugate or pseudo-squamate.
