202 SPOLIA ZEYLANICA. 



The second antenna, mouth parts, and the first four pairs of 

 swimmhig legs are similar to those of the female. 



The fifth swimming legs are of interest, in that both are 

 present, thus resembling the condition found in E. attenuatus 

 (Dana) and E. elongatus. The left leg is the longer, and 

 when folded back reaches to the extreme tip of the furcal 

 rami ; the right leg is somewhat stouter, and the terminal 

 segment bears a stout seta. 



An immature male was also obtained in the same locality. 

 In this individual the abdomen consists of three segments 

 only, the third not yet having undergone division. Both legs 

 of the fifth pair were present, but were equal in size.
