Figure 110. — Pylopagurus corallinus (Benedict). A, an- 

 terior part of body in dorsal view ; B, right chela, outer 

 surface; (from two specimens) 3 mm. indicated. 



Chelipeds unequal, right larger than left. Up- 

 per surface of major chela flattened or slightly 

 excavated, covered with small, slender spines be- 

 coming flattened and mushroom-shaped on im- 

 movable finger; hand fringed with spines, often 

 alternately large and small, becoming longer near 

 tips of fingers, inner surface with spinose tuber- 

 cles between base of dactyl and recess receiving 

 carpus, recess bounded by crest; carpus approxi- 

 mately as long as palm, upper surface thickly set 

 with sharp, spiny granules, margin with rows of 

 small spines; merus compressed, quadrilateral 

 when viewed laterally. Minor chela with hand 

 broad, compressed ; fingers broad, gaping at base ; 

 carpus compressed, and surmounted by an inner 

 row of small and an outer row of larger spines; 

 merus compressed. Carpus and propodus of first 

 walking leg, and carpus of second, crested with 

 acute spines. 



Measurements. — Length of carapace: male, 

 7 mm. ; ovigerous female, 5 mm. 



Color. — Large cheliped with merus and carpus 

 blotched red and white; small cheliped and walk- 

 ing legs banded with same colors (Benedict, 

 1892). 



Habitat. — In tunicates, stony corals, and bryo- 

 zoans; 21 to 56 fathoms. 



Type locality.— OS Key West, Fla. 



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

Figure 111. — Pylopagurus rosaceus Milne Edwards and 

 Bouvier. A, anterior part of body in dorsal view ; B, 

 right chela, outer surface with detail shown only on 

 dactyl; (from two specimens) 3 mm. indicated. 



Recognition characters. — Anterior shield of 

 carapace subcordate, somewhat truncate posteri- 

 orly ; anterior margin with three projections, ros- 

 trum obtuse and slightly advanced beyond strong 

 lateral projections, each terminating in a minute 

 spine; sides of dorsal surface and anterior surface 

 with a few tufts of setae. Eyestalks stout, con- 

 siderably shorter than anterior shield, distinctly 

 dilated distally, and with three or four pencils of 

 setae in line along upper surface ; eye scales acute 

 anteriorly, each ending in an acute, subterminal 

 spine. Antennal peduncle extending beyond eye, 

 flagellum slender and longer than body; acicle 

 strongly curved, reaching almost to distal edge of 

 cornea.
