 Carapace ovate, convex, smooth, and not areolated. Rostrum promi- 

 nent, depressed, flattened above, and having a small triangular notch at 

 the tip. No preorbital tooth; postorbital small. The two teeth on the 

 sides of the carapace are much smaller than in E. productus, and the mar- 

 gins between them are convergent anteriorly. The chelipeds are very 

 similar to those of productus. Ambulatory legs subcylindrieal; dactyls 

 stouter than in the preceding species.

 retracted. Merus of the external maxillipeds short, the external angle 

 obtuse, the internal angle incised; outer margin of the exogiiath dilated.
