THE SPIDER CRABS OF AMERICA 33 



E-. No postorbital granule. Sternum of male closely covered with 

 pearl}' granules. Median carina of rostrum sharp, continued to 

 front edge. Gape narrow between fingers of adult male 



margaritaria, p. 43. 



D^. Rostrum not triangular, ver\' broadlv' rounded, widest in front of 



its origin. Concave surface of basal antennal article very broadly 



triangular algicola, p. 41. 



C^. Rostrum thick, subtriangular, not hollow beneath. 



D'. Propodus of first leg four or more times as long as dactylus. Pro- 

 podus of last two legs considerabl}^ longer than dactylus and 



slightly curved macrodera, p. 44. 



D-. Propodus of first leg twice, or at most three times as long as dactylus. 

 Propodus of last two legs very little longer than dactylus and 

 strongly curved grossipes, p. 45. 



Macropodia occidentalis Guilding (Trans. Linn. Soc. London, vol. 

 14, 1824, p. 335), from the Caribbean Sea, is probably a species of 

 PodocJiela, but the description is too short to permit of its exact 

 determination.
