deflexed rostrum, the tip of which is cleft or emarginate. The eye- 
stalks are long, and the corneae, which are rather ventral than terminal in 
position, can be completely retracted from dorsal and usually also from 
ventral view. The orbit is formed by a sharply-arched supra-ocular 
eave, which is in contact either with an excavated post-ocular spine or 
with an intercalated spine as in Maia, and is partly or entirely com¬ 
pleted below and in front by a process of the broad basal antennal 
joint. The mobile portion of the antenna is completely exposed. 
The buccal frame is broadened in front: the merus of the external 
maxillipeds is broader than the ischium, and has its external angle 
expanded and its internal angle notched for the insertion of the palp. 
The chelipeds in the adult male are as long as or a little longer 
than the carapace, are a little stouter than the other legs, and have the 
palm broader than the other joints, and the fingers arched to meet only 
at the tip. The chelipeds in the female are slenderer than the other 
legs, are about the same length as the carapace, and have slender palms 
and almost straight fingers. The ambulatory legs are moderately 
elongate, subcylindrical, and have the dactyli not much or not at all 
shorter than the propodites. 
Abdomen, in both sexes, seven-jointed. 
Key to the Indian species of Micippa. 
I. Rostrum very broad, ending in four sharp lobes or spines 
(i.e , each lobe of the rostrum bilobed). 
II. Rostrum moderately broad, ending in two long sharp lobes 
or spines (i.e., each lobe of the rostrum simple), not 
indexed at tip. 
III. Rostrum moderately broad, indexed at tip j ending in two 
insignidcant blunt lobes, each of which has a small 
tooth at its external angle :— 
1. Three large pearl-like tubercles embedded 
in the posterior margin. 
2. Two small pearl-like tubercles embedded 
in the posterior margin, with a group of 
small spinules between them.
