Paramicippa asperimanus, Miers, Zoology H. M. S. 'Alert,' pp. 517 and 525. 



Body and ambulatory legs closely covered by a woolly tomentum. 

 Carapace with, the regions well defined by smooth sulci, the hepatic 

 regions sunken and pinched in, the surface closely and unevenly 

 granular : the lateral margins are armed with knob-tipped spinules, 

 of which there are sometimes as many as six, sometimes as few as two, 

 on either side. 



The rostrum consists of a broad lamina which in the female is 

 quite vertically, but in males is not so much deflexed, its sides are 

 gently sinuous, and it ends in four sharp-cut lobes. The eyes are 

 completely retractile within the orbits. 



The basal antennal joint is short and is extremely broad anteriorly, 

 its greatly produced antero-external angle completing the orbit below 

 and in front. The mobile portion of the antenna, which is freely 

 exposed, varies in length and in the form of the flattened 2nd joint 

 of the peduncle. In some males (var. mascarenica) the mobile portion 

 of the antenna is half the length of the horizontal portion of the 

 carapace, and the length of the 2nd joiut is rather more than one-third 

 the breadth of the rostrum at its own point of origin. But in all 

 ovigerous females, and in certain males, the mobile portion of the 

 antenna is between one-third and one-fourth the length of the hori-
