DECAPOD CRUSTACEANS OF THE WEST INDIES 141 



Habitat. — Unknown, presumably in or near fresh water. 



Distribution. — Known only from the type-series labeled "West 

 Indies." 



Remarks. — The type-series of E. granulata, consisting of four 

 immature specimens, was described by Rathbun in 1893 as "all more 

 or less mutilated." Unfortunately, the specimens have apparently 

 deteriorated even more with time; all of the material is now virtually 

 macerated, except for the imperfect and extremely fragUe remains of 

 one carapace and one sternum. In view of the immaturity of these 

 specimens and the lack of a specific type-locality, the species may 

 remain a species inquirenda indefinitely unless it can be shown to be 

 a synonym of E. armata.

 Republic of Haiti]; 1905, p. 319, pi. 18 (XVI): fig. 8. 



Diagnosis. — Carapace not very convex longitudinally or trans- 

 versely, rather broad, about three-fifths as long as wide; cervical 

 groove distinct, sinuous, convex forward mesially, concave forward 

 laterally; anterolateral margin denticidate throughout, even onto 

 posterolateral margin, and marked by two broad, shallow indenta- 

 tions, one at end of cervical groove, one near outer orbital angle; front 

 delimited dorsally by strong, tuberculate, transverse crest, hiding all 

 but submedian lobes of true frontal margin from dorsal view. Third 

 maxilliped mth merus subquadrate, lateral margin feebly convex, 

 distal margin somewhat concave; exopod extending beyond ischiomeral 

 articulation. Pereiopods not unusually long or slender. Chela without 

 prominent, swollen protuberance on outer surface at base of fingers. 

 First pleopod of adult male armed distally with scattered, short, stout 

 spines; elongate lobe directed laterally in situ. A large species, maxi- 

 mum carapace length in midline about 64 mm. 



Habitat. — In and near fresh water. 



Distribution. — Hispaniola.
