NO. 3 GARTH : SOME NEW SPECIES OF BRACHYURAN CRABS 89 



cluster of spinules beneath ft. Third lateral tooth obtuse, blunt, and 

 with a serrate edge; larger than other teeth. Carapace widest at fourth 

 lateral tooth. 



Description : Carapace broadly hexagonal, about two thirds as long 

 as wide, more convex longitudinally than transversely, hairy, gastric 

 areole prominently indicated. Front approximately one third the width 

 of the carapace, its lobes slightly convex, median notch shallow, edge 

 thin. Eyestalks narrowing distally, a slight constriction at base of cor- 

 nea. Orbits transverse, not separated from the front by a prominence, 

 trending outward rather than forward, a superior fissure internally 

 and a notch externally separating the broad, low, granulate, slightly 

 convex lobe from the obtusely angled and little-advanced exorbital 

 tooth. Lateral teeth five in number, counting the exorbital, slightly up- 

 turned, edges serrate or denticulate; second tooth low, rounded, and 

 separated from the first by a shallow U; third tooth obtuse and blunt, 

 larger and more prominent than other teeth, bearing several conspicuous 

 denticles on its inner slope; fourth tooth smaller, acute, outer margin 

 curved, inner margin straight, carapace widest at this level; fifth tooth 

 postlateral in position, small and sharp. Posterolateral margins exceed- 

 ing anterolateral and moderately convergent. Two depressions at the 

 union of the postbranchial and metagastric regions. 



Antennules large, folding transversely. Antennae minute, lodged in 

 the orbital hiatus; flagella extending beyond eyes, slender. Epistome 

 short. Buccal cavity broadening anteriorly. Merus of outer maxillipeds 

 broader than long, exterior angle produced, rounded, interior angle 

 faintly notched to receive the short, thicic, hairy, cylindrical palpus. (See 

 pi. 25, fig. 4.) 



Chelipeds massive, unequal, hairy. Merus with a subterminal tooth 

 surmounted by several sharp granules. Major carpus subglobular, granu- 

 late, bearing a single, short, sharp spine (broken in the holotype speci- 

 men) at its inner superior angle and a row of three or four spinules 

 beneath it; a sulcus parallel to the margin adjoining the palm. Major 

 manus bare and glistening; palms convex above and beneath; superior 

 margin with two parallel granulate ridges interspersed with long, 

 shaggy hairs and extending on to the dactyl, which curves inward. 

 Fingers of major manus irregularly toothed, pollex scarcely deflexed, 

 meeting dactyl with an elongate gape. Fingers of minor manus more 

 slender, lower margin of manus almost straight. Color of fingers not 

 continued on palms. (See pi. 25, fig. 2.)
