Munida valida, sp. nov. (Pl. 1.) 
A large species with the general appearance of M. Bamfia, but at 
once distinguished from it, and from I. tenuimana, and Caribea? Smith 
as well, by the short and obtusely rounded epimera of all the abdominal 
somites. 
Excluding the rostrum, the carapax is about three-fourths as broad as 
long; including the rostrum, about four-sevenths as broad as long, the 
rostrum being more than a fourth the entire length. The rostrum and 
the spines at its base are shorter and stouter than the M. Bamffia, and 
the latter are about three-fifths as long as the rostrum, strongly diver- 
gent and directed somewhat upward, while the rostrum is herizontal. 
The number and position of the spines on the dorsal surface and along 
the lateral margins of the earapax are very nearly as in M. Bamffia, ex- 
cept that there are no spines along the raised posterior margin. The 
orbital part of the anterior margin is more oblique than in M. Bamfia, 
and the antennal spine is not, as in that species, at the antero-lateral 
angle, but the margin between the antennal and hepatic spines is only 
a very little more oblique than the orbital margin, and the antero-lateral 
angle is really formed by the hepatic spine. The carapax is apparently 
wider and less convex than in AZ. Bamfia, the sutures of the dorsal sur- 
face are deeper, and the transverse ruge are apparently fewer and more 
conspicuous. 
The eyes are about as large as in M. Bamffia, but not so strongly com- 
pressed. 
The basal segment of the antennula is armed with a slender spine 
arising from the prominence on the outer margin and directed forward, 
a larger spine on the outer edge of the distal end, and between these 
two a long spine, two-thirds as long as the segment itself, directed 
obliquely upward, while at the distal end of the inner side there is only 
an inconspicuous dentiform spine in place of the very long and slender 
spine found there in M. Bamffia, tenwimana, and Caribea? Smith. The 
flagella of the antennz are subcylindrical, slender, nearly naked, and 
not far from twice as long as the entire length of the body. 
The merus of the external maxilliped is not distinctly tapered dis-
