pi. xxxvi. figs. 5-7. 
Carapace symmetrically sculptured, closely crisply and finely 
granular, and with the hepatic regions deeply excavate : there are three 
coarse spinules, disposed in a triangle base outwards, on either branchial 
region, and a denticle at the anterior boundary of the branchial region ; 
and on the posterior margin are three smooth polished globules “ exactly 
resembling pearls ” inset. 
The rostrum is long, vertically deflexed in both sexes, and incurved 
at the tip, which ends in two shallow lobes — the outer angle of each 
lobe being marked by a spinule. 
The basal antennal joint has its antero-external portion greatly 
produced to complete the floor of the orbit. 
The chelipeds in the male are a little longer than the carapace, and 
have the palms broadened and inflated, and the fingers closely apposable 
only at the tip. In the female the chelipeds are very much slenderer 
than the other legs, are only as long as the post-orbital portion of the 
carapace, and have the hand very slender and tapering. The ambula¬ 
tory legs are remarkable for their large obtriangular foliaceous mero- 
podites, which in the first pair are specially remarkable, as they are 
closely apposable to the front, to form, as in Calappa , a shield. 
In the Museum collection are specimens from both sexes from the 
Andamans, from Ceylon (34 fms.), and from the Maldives (20-30 fms.). 
Micippa margaritifera , var. parca nov. I distinguish, provisionally, 
as a variety, two ovigerous females from the Andamans, in which the 
middle “pearl” on the posterior border is replaced by a group of 
spinules, and in which the meropodites of the ambulatory legs are even 
more broadly foliaceous.

Carapace elongate, siibcylindrical, with the gastric region greatly 
elevated ; the anterior part of the gastric region , along with the front , being 
vertically deflexed. The rostrum is formed of two little horns, each of 
which is sharply bifurcate at the tip, one branch being directed forwards 
and outwards, the other being recurved upwards. The eyes are small 
and are sunk in small tubular orbits formed in the typical Periceroid 
manner. The antennae are small : the basal joint has its antero external 
angle separated from the rest of the joint by a deep cleft. The external
