of larger. Smaller wrist similar in shape to larger and has an inner tooth. The black color of thumb 
runs back a little on the hand, forming a convex outline. Otherwise resembling L. longimana.

Lopharta’a A. Milne Edwards. Ann. Sei. Nat. (4), .win, 43, 1862. 
Carapace moderately broad, convex in both directions, with regions generally well delimited and 
subdivided into lobes, and the surface generally (not always) granular; the antero-lateral borders have 
an independent crest-like edge, generally thin and sharp and distantly fissured; the postero-lateral 
borders rather concave. Front a little deflexed, about a fourth the greatest breadth of carapace in 
extent, grooved and emarginate in middle line. Orbits large, the three suture lines near outer angle 
distinct. Eyes on short thick stalks. Antennules folding obliquely transversely; inter-an ten n alary 
septum broad. Basal joint of antennae short, touching front only; flagellum lodged in orbital hiatus. 
Merus of external maxillipeds with front edge a little oblique. 'Chelipeds equal in both sexes; fingers 
not hollowed at tip. Long joints of legs with sharp crest-like upper borders. Abdomen of the male 
five-jointed, the third to fifth somites being fused.

Platypodia rpcctabilis Rathbun, Ann. Inst. Jamaica, I, 13,1897. 
Surface lobulated, granulate. Antero-lateral crest extending very far back and continued by a 
small transverse crest on carapace in line with cardiac region; marginal crest cut by three narrow 
fissures; postero-lateral borders concave. Front deflexed, presenting two oblique truncate lobes in a 
dorsal view. In a front view these lobes are concave. Hands short, compressed, surmounted by a 
sharp, entire crest; outer surface covered with granules, irregularly placed on upper portion, but form- 
ing three or four longitudinal lines on lower part. Fingers pointed, channeled, their prehensile borders 
denticulate, also a broad lobe at base of immovable finger. Ambulatory legs short, compressed; nails 
very sharp. Suture lines faintly visible between the third, fourth, and fifth abdominal segments in 
the male. 
Color, chocolate brown, with some yellow spots bordered with blue and black; similar spots on 
chelipeds. Legs red, with tricolored bands of yellow, blue, and black. Eggs reddish yellow. (A. 
Milne Edwards.) 
Length of female, 13 mm.; width, 19.3 mm.; fronto-orbital width, 9 mm.; width of front, 5 mm.

Genus LEPTODITJS A. Milne Edwards. 
Leptoclius A. Milne Edwards, Ann. Sei. Nat. (4), XX, 2,84, 1863. 
Carapace broad, suboval, moderately convex anteriorly, flat in posterior half; regions well 
delimited and fairly well lobulated in the anterior two-thirds, but not posteriorly. Antero-lateral 
borders arched, very long, not very thick, cut into five well-developed teeth, including the orbital 
angle; postero-lateral borders moderately convergent, not concave. Fronto-orbital border more than 
half the greatest width of carapace; front a fourth or more than a fourth the greatest width of carapace. 
Front little deflexed, rather prominently sublaminar, notched in middle line, separated from supra- 
orbital margin by a notch. Orbital margin with two suture lines above and one more distinct just 
below outer angle; usually a prominent tooth at inner angle of lower edge of ox-bit. Eyes on short thick 
stalks. Basal antennal joint short, meeting the front at inner angle of flagellum, which is about as 
long as orbit and is lodged in orbital hiatus. Anterior edge of merus of external maxillipeds nearly 
transverse, with commonly a small tooth near the antero-internal angle. Chelipeds unequal in both 
sexes; fingers spoon-shaped, or hollowed out at the tips. Legs compressed, the upper edges rather 
sharp. Abdomen of male five-jointed, the third to fifth somites fused.
