DECAPOD CRUSTACEANS OF THE WEST INDIES 117 



teeth; posterior 3 teeth of dorsal series placed on carapace behind 

 level of orbital margin. Eyes with cornea noticeably narrower than 

 eyestalk but well pigmented. Second pereiopods subequal, very slender, 

 with carpus and distal part of merus multi-articulate, chela very 

 small, little longer than distal article of carpus. Third pereiopod with 

 propodus six or seven times as long as dactyl. Color translucent crim- 

 son, Mdth antennular and antennal fiagella, first pereiopods, and extreme 

 distal portions of third to fifth pereiopods white. A rather small 

 species, maximum postorbital carapace length about 12 mm. 



Habitat. — Marine or brackish water in sinks or roofless caves. 



Distribution. — Several marine or brackish pools near the coast 

 of Cuba. 



Remarks. — All of the more than 100 specimens examined of Bar- 

 bouria cubensis have an appendix masculina on the second pleopod. 

 It is possible that the female of this shrimp is still unknown.
