DECAPOD CRUSTACEANS OF THE WEST INDIES 217 



dissimilar and unequal in males, small and subequal in females; 

 fingers of major chela of male about twice as long as palm, slender, 

 widely gaping, not unusually compressed. Walking legs pubescent, 

 especially on extensor margins of merus, carpus, and propodus. Hair- 

 fringed ventral opening present between coxae of third and fourth 

 pereiopods. Denuded first pleopod of male terminating, in posterior 

 view, in obliquely truncate tip directed distolaterally (fig. 73e). A 

 medium-sized species, maximum carapace length in midline about 

 18 mm. 



Habitat. — Mud flats. 



Distribution.— Northeastern Florida to Rio de Janeiro, Brazil 

 (Cuba, Jamaica, Puerto Rico, Guadeloupe, Curacao).

Diagnosis. — Carapace subtrapezoidal, nearly two-thirds as long 

 as wide, moderately convex longitudinally, surface rather smooth, 

 partially covered with pattern of small irregular patches of scurflike 

 pubescence especially on lateral regions in males; fronto-orbital 

 distance slightly less than maximum carapace width; front widening 

 toward base, width between posterodistal angles of basal segments of 

 eyestalksjwith eyes retracted, about one-third of fronto-orbital distance; 

 lateral margins diverging posteriorly from outer orbital angles, 

 curving regularly into strongly convergent posterolateral ridges. 

 Cornea moderately swollen, occupying slightly less than one-third of 

 extensor surface of distal segment of eyestalk. Chelipeds greatly 

 dissimilar and unequal in males, small and subequal in females; 

 fingers of major chela of male distinctly longer than palm, slender, 

 widely gaping, not unusuafly compressed. Walking legs of males 

 pubescent, especially on extensor margins of merus, carpus, and pro- 

 podus; those of females bare on carpus and propodus except for scat- 

 tered setae. Hair-fringed ventral opening present between coxae of 

 third and fourth pereiopods. Denuded first pleopod of male terminating 

 in posterior view, in broadly truncate, centrally emarginate tip curv- 

 ing distolaterally (fig. 73^). A medium sized species, maximum cara- 

 pace length in midline about 22 mm.
