ward ; the antero-lateral angles form a rounded shoulder. Rostrum broad at 
base, nearly horizontal; sides converging near tip, which is blunt; upper 
surface nearly flat, lightly granulated. The rest of the upper surface of the 
carapace has a coarser granulation. There is a conspicuous hooked tooth on 
the third and the fourth abdominal segments, and in some specimens there is 
a rudimentary one on the second and the fifth segments; the teeth on the 
third and fourth segments have denticulated margins in adult specimens ; 
abdominal pleuree long and narrow. Chelipeds very long, lightly tubereu- 
late ; chela long, slender; fingers rather short, smooth, with straight, denti- 
culated prehensile margins. The meri of the ambulatory legs granulated ; 
superior border produced to a crest, the edge of which is entire; the lower 
margin of the meri is also entire ; the carpi have three tuberculated ridges, 
one of which is superior, two external ; the propodites lightly tuberculated ; 
dactyli smooth, their hind margins armed with about five teeth. Eye 
spineless, nearly hidden under the rostrum. Antennz shorter than the cara- 
pace ; first, third, and fourth joints armed with an external spine. 
Length, 30 mm.; carapace, 16 mm.; breadth, 9.5 mm.; rostrum, 5 mm. ; 
cheliped, 40 mm. (merus, 13 mm., carpus, 4.5 mm., propodite, 17 mm., dacty- 
lus, 7 mm.).

Near JM. longimana (Elasmonotus longimanus A. M. Edw.), from which it 
differs in having the rostrum more nearly plane and more tapering, the 
merus of the cheliped much less strongly tuberculated, the meri of the 
ambulatory limbs more strongly carinated, with lower margin entire instead 
of denticulate ; the spine on antennal peduncle is more prominent, while the 
tooth on the second segment of the abdomen is absent, or at best rudi- 
mentary. The chelipeds of the female specimen of MZ. carinipes are lost.

In this species the whole surface of the body and appendages is naked 
and free from spines and tubercles. The carapace is rather flat above, with 
subparallel sides ; the gastric region is protuberant, and separated from the 
hepatic and cardiac areas by conspicuous furrows. The surface of the cara- 
pace is punctate, lightly granulate and rugose on the branchial regions.
