274. CRABS OF THE FAMILY PERICERIDE—RATHBUN. 
It agrees with the specimens described in all essential particulars. 
The tubercles of the frontal region are, however, not apparent. The 
tooth at the antero-external angle of the basal joint is sharp and curved. 
The ambulatory leg is bordered above and below by a thin lamellate 
crest cut into teeth, which are arranged almost as in the figure cited. 
This crest is most noticeable on the meral joint. The teeth of the me- 
rus of the cheliped are also thin, and partake of the same character.
