REPORT ON THE BRACHYURA.

distal extremity does not attain the apex of the merus- joint of the endognath. The 
chelipedes are very slender; the merus is nearly as long as the carapace, subcylindrical 
and granulated ; carpus very short, smooth ; palm shorter than the merus, smooth, and 
tapering distally ; fingers little more than half as long as the palm, very slender, with 
the tips incurved and armed with several distant teeth, between which are smaller 
grannliform teeth. Ambulatory legs slender and moderately elongated, with the dactyli 
styliform and slightly longer than the penultimate joints, 
yellowish-brown .

Bahia (shallow water), a sterile female. 
Stimpson’s description of Iliacaniha subglobosa was also based on a sterile female ; 
it is evident, therefore, that the difference in the length of the dactyli of the chelipedes 
is not a sexual character, and it would appear from his description that the carpus and 
palm of the chelipede in Iliacantha subglobosa are granulated, and the teeth of tbe 
dactyli more acute. 
Section IV. The carapace is not produced so as to cover in great part the ambulatory 
legs. The chelipedes are robust, not slender ; the palms and fingers compressed, not 
slender and elongated (Ebaliinae, Stimpson, part).
