and the prehensile edges straight and very regularly dentate. Thetwo 
first pairs of ambulatory legs are nearly alike, twice as long as the 
chelipeds, and nearly or quite naked; the propodus is a little shorter 
than the merus, very slightly compressed, and smooth, but slightly 
grooved longitudinally ; the dactylus is once and a half as long as the 
propodus, very much compressed vertically, slightly curved, of nearly 
uniform breadth to a short distance from the acuminate tip, and very 
smooth. The third and fourth pairs of ambulatory legs are nearly alike, 
searcely half as long as the first and second, slender, and covered with 
short pubescence, except upon the dactyli. The propodus is much 
shorter than the merus, not very much shorter than the carpus, nearly 
cylindrical, and not expanded distally; the dactylus is very short and 
strongly curved.

The very small eyes and the great breadth and prominent antero- 
lateral angles of the carapax at once distinguish this species from E. 
mascarone, of the Mediterranean, and from the Japanese HE. sexdentata. 
It is also evidently distinct from EF. granulata Norman, which, however, 
has apparently not been fully described. The genus has not, I think, 
been recorded from America before, although a species occurs in the 
Bay of Panama.

I have had no European specimens for comparison, and have seen 
only a tracing of Rouxs figure, with which the specimens before me 
agree well. In these specimens the propodus in the posterior pair of 
legs is a little more than two-thirds as long as the merus, and the dac- 
tylus is very short and closes against the somewhat oblique and spinous
