joint extends as far forward as that of the eheliped and is decidedly 

 laterally compressed ; the carpus is four-fifths as long as the merus and 

 similarly compressed ; the propodus is a trifle longer than the carpus, 

 also compressed, with the superior lateral margin spinulose and gran- 

 ular; the dactyl is a trifle longer than the carpus and propodus con- 

 sidered together and is very slender, compressed cylindrical, curved, 

 with the upper and lower margins ciliate, the tip horn-like, acuminate. 

 The fourth legs are small, with the propodus squarish, the inferior 

 lateral margin with a line of corneous scales ; the dactyl is placed at 

 the end of the propodus, stocky, with a curved tip and the lower 

 margin spinulose. 



The fifth legs are characteristically reflexed, weakly subchelate, 

 with a large patch of movable corneous scales on the outer face of the 

 propodus and dactyl.
