240 DB. J. G. DE MAN ON THE PODOPHTHALMOFS 



The red peduncles of the aatennse and antennules are also marked 

 with narrow longitudinal pale lines. The chelipedes are of the 

 same red colour, that is more intense on the upper than on the 

 under surface ; the dentiform acute tubercles with which they 

 are armed are of a paler colour and, especially those of the hands, 

 contrast rather strongly with the red ground-colour of the palm. 

 The fingers haye subexcavate corneous tips, the upper margins 

 of which are black. The first and second pair of ambulatory 

 legs are also of the same red colour, and are marked, moreover, 

 with longitudinal pale lines bordered by a darker red. The 

 upper margins of the meropodites of the first .pair of ambu- 

 latory legs are marked on their upper margins with a similar 

 longitudinal pale line ; this line divides near the middle of the 

 upper margin into two pale lines, one of which proceeds further 

 forwards on to the upper margin and is continued along the upper 

 margins of the following joints, while the other is directed 

 towards the middle of the external surface of the joint, and is then 

 continued on to the middle of the outer surfaces of the following 

 joints. The ambulatory legs of the second pair are marked with 

 precisely similar lines, except that the outer surfaces of the 

 meropodites are marked moreover with a third longitudinal pale 

 line on the middle of their outer surfaces, which, however, is not 

 continued on to the following joints. The under margins of the 

 joints are also of a pale colour, which is especially distinct on 

 those of the propodites and dactylopodites.
