Type locality. — Cruz del Padre, Cuba, and Key 

 West, Fla. 



Knoxon range. — Near Beaufort, N.C., to Flor- 

 ida; Cuba.

Pilutnnus pannosus Rathbun, lS96b, p. 142. — Rathbun, 1930a, 

 p. 514, figs. 4-5 (rev.). 



Recognition characters. — Carapace about three- 

 fourths as long as wide, almost entirely covered 

 with unevenly distributed, soft, thick, velvety 

 pubescence, with scattered longer club-shaped 

 setae giving ragged appearance; lobulations of 

 anterior portion of carapace and tubercles of 

 chelipeds showing through pubescence. Anterior 

 half of carapace and upper surface of chelipeds 

 and legs dotted with beadlike tubercles. Ante- 

 rolateral margin with four triangular spines 

 (outer orbital small) having slender forward- 

 projecting tips; subhepatic spine between first 

 and second tooth well developed. Frontal lobes 

 (when well formed) broadly subtriangular, 

 granulate on margin, separated by a V-shaped 

 notch; outer tooth of front almost triangular, 

 acute (blunt at tip in some specimens). Upper 

 margin of orbit with three truncate teeth covered 

 by pubescence, lower margin with a row of short, 

 stout, truncate teeth or tubercles. 



Chelipeds with upper surface tuberculate but 

 usually with large part of outer surface smooth 

 and naked; small hand with outer surface often 

 rough with rows of spines; dactyls with a few 

 tubercles near articulation. Male with shallow 

 grooves on fingers, female with well-defined 

 grooves on minor fingers and fixed major finger. 

 "Walking legs pubescent, fringed with club-shaped 

 setae mixed with long fine hair. 



Measurements. — Carapace : male, length, 9 mm. ; 

 width, 12 mm. 



Color. — Carapace under pubescence and bare 

 part of palms bright red (Milne Edwards in 

 Rathbun, 1930a). 



Habitat. — Pearse and Williams (1951) listed 

 this species as taken from a submerged rocky reef, 

 and Rathbun (1930a) listed it from similar situa-

tions, as well as from sponges and corals. A few 

 feet to 9 fathoms. 



Type locality. — Key West, Fla. 



Known range. — Bogue Sound off Beaufort, 

 N.C., to Port Aransas, Tex.; West Indies to 

 Virgin Islands. 



Remarks. — The species has rarely been taken 

 north of Florida. Rathbun (1930a) listed oviger- 

 ous females in December and January from 

 Florida, and they are known from April to 

 August between South Carolina and Cuba.

Recognition characters. — Regions of carapace 

 protuberant, surface pubescent, except naked and 

 thickly granulated on anterior and anterolateral 

 regions; depressions between regions broad, oc- 

 cupying as much area as regions themselves. 

 Front consisting of two large lobate masses 

 deeply separated from each other and from orbits. 

 Orbital region protuberant and granulate, margin 

 crenulated with granules, with two fissures above 

 and two very narrow ones below. Anterolateral 

 margin with three triangular, spine-tipped teeth 

 of moderate, equal size ; subhepatic tooth distinct.
