Figure 128. — Iliacantha subglobosa Stimpson. Female in 

 dorsal view, 5 mm. indicated. 



Recognition characters. — Carapace orbicular, 

 smoothly and evenly convex, finely granulate, un- 

 armed except posterior border with three spines ; 

 lateral spines subtriangular, blunt; median one 

 higher, longer, conical, and curved upward. Front 

 deeply grooved above, broadly notched anteriorly 

 and with spiniform angles of branchial channels 

 extending beyond it. Margin of carapace distinct, 

 somewhat acute on hepatic region and anterior 

 portion of branchial region, indistinct beyond ; 

 hepatic region swollen; intestinal region slightly 

 protuberant above base of median spine. 



Chelipeds 2.5 times as long as carapace, exclud- 

 ing spine, finely granulate; merus more sharply 

 granulate than carpus and hand ; fingers slender, 

 longer than palm, armed with needlelike teeth. 

 Walking legs slender, smooth; merus as long as 

 three terminal articles; dactyls grooved, and with 

 two fringes of hair on upper and posterior sur- 

 faces. Male abdomen gradually tapering from 

 fifth to seventh segment. 



Measurements. — Male: carapace length, 21 

 mm., width, 16 mm.; chela length, 22 mm.; fin- 

 gers, 13 mm. 



Habitat. — Fifteen to 215 fathoms. 



Type localities. — Three stations in Florida 

 reefs, 40-80 fathoms. 



Known range. — Off Cape Hatteras, N.C., to 

 northwest Florida ; through West Indies to Bar- 

 bados.

Figure 129. — Iliacantha intermedia 

 Miers. Male in dorsal view, 5 mm. 

 indicated. 



Recognition characters. — Similar to /. subglo- 

 bosa, but carapace more coarsely granulate; pos- 

 terior spines shorter, flattened, triangular, con- 

 nected by prominent line of granules. Front 

 deeply grooved above, broadly notched anteriorly, 

 and with spiniform angles of branchial channels 

 extending beyond it. Margin of carapace dis- 

 tinctly granulate; intestinal region not protuber- 

 ant above median spine. 



Chelipeds slender, nearly as long as carapace; 

 merus cylindrical and granulate with coarser 

 granulations proximally; hand smooth, somewhat 

 inflated proximally but tapering to slender fin- 

 gers ; fingers about half as long as palm, incurved 

 at tip, and denticulate on opposed margins. Male 

 abdomen widened at convex-sided sixth segment. 



Measurements. — Male: carapace length, 16 

 mm., width, 12 mm. ; chela, length, 13 mm. ; fin- 

 gers, 4 mm. Female: carapace length, 27 mm., 

 width, 21 mm. 



Color. — Gray without markings of any kind. 



Habitat. — Five and one-half to 180 fathoms. 



Type locality. — Bahia, Brazil. 



Known range. — Off Beaufort, N.C., to north-
