208 SPOLIA ZEYLANICA. 



Endopod 3 bears seven setae, and a few spinules are present 

 posteriorly. 



The Third and Fourth Pairs of Legs are very similar to the 

 second pair, but the terminal spine on the fourth exopodite 

 is shorter than the segment preceding it. 



The Fifth Pair of Legs. — These, as in all adult males in this 

 genus, are asymmetrical : the left leg consists of a somewhat 

 swollen basal portion and a terminal part composed of four 

 segments. There is an obvious hinge between the basal and 

 terminal portions, and the proportions of the segments are 

 20 : 15 : 15 : 15 : 12. The last segment ends in two 

 unetpal spinous processes, and the penultimate segment bears 

 a single spine at its distal external angle. The right leg is 

 composed of a basal and two free segments. It is much 

 shorter than the left, and ends in two unequal spines.

Numerous examples were obtained in the various localities, 

 and its distribution in Indian waters appears to be almost 

 universal. I agree with Scott {loc. cit., 1909) that the minute 

 differences noted by Wolfenden between specimens taken in 

 the North Atlantic Ocean and those from Indian seas are not 

 of sufficient importance to justify the separation of the latter 

 as a special variety.
