Body and ambulatory legs covered with a woolly tomentum. 



Carapace with the regions fairly well-defined, the hepatic regions 

 depressed, and the surface closely and evenly granular. From the 

 granular surface there usually, but not always, arise several large verti- 

 cal spines, which are typically disposed as follows: — one on either 

 supra-ocular hood, two on the gastric region in the middle line, and two 

 placed obliquely on either branchial region. Any or all of these spines 

 may be suppressed. The lateral margins are armed with an irregular 

 series of spines or spinules, and a few spinules may exist on the pos- 

 terior border in the middle line. 



The rostrum is deflexed nearly vertically in the adult female, less 

 vertically in the adult male, and at an angle of 45° or less in the young 

 male : it ends in two curved divergent spines. 



The basal antennal joint is produced at its antero- external angle to 

 assist in the formation of the floor of the orbit, but there is a wide 

 hiatus between this process and the post-ocular spine, so that the floor 

 of the orbit is incomplete. 



The chelipeds in the adult male are as long as the carapace, are 

 not much stouter than the other legs, and have slender palms, and long 

 slender fingei'S which, though nearly straight, are closely apposable only 

 in their distal half. Iu the adult female the chelipeds are equal in 

 length to the post-orbital portion of the carapace, are slenderer than 

 the other legs, and have tapering palms and minute fingers. The merus 

 and carpus of the ambulatory legs are sometimes swollen. 



In the Museum collection are specimens, representing all the 

 varieties of this species, from Mergui, Burma, Orissa and Malabar, as 

 well as from Hongkong and Nagasaki. 



This species shows quite as well as M. cristata the close relation 

 of Micippa to Maia.
