218 SPOLIA ZEYLANICA. 



The second antenna and mouth parts are similar to those 

 of other members of the jrenus. 



The First Pair of Legs. — The first basal joint bears no 

 external spine or internal seta ; the external margin bears a 

 series of fine curved spinules, diminishing in size proximally ; 

 the second basal joint bears no marginal spine, but carries a 

 single seta on its inner distal angle. 



The exopodite consists of three segments : exopod 1 bears 

 no marginal spine ; exopod 2 has a single spine, as usual ; 

 exopod 3 in most cases bears a single spine on the external 

 margin at its distal extremity, but m two of the specimens 

 examined (a ^ and a ?) there was a second spine present at the 

 junction of the middle and distal thirds. The end spine is 

 long and slender, and is equal in length to the preceding two 

 segments. The endopodite consists of a smgle segment having 

 a well-marked rounded swelling on the external border, and 

 across the base of this swelling is a transverse row of needle- 

 like spines. 



The Second Pair of Legs. — The first basal bears a single seta 

 internally, and is finely serrated on the proximal two-thirds 

 of the outer margin. The seoond basal is produced at both 

 the internal and external distal angles in a triangular spinous 

 process. 



The exopodite consists of three segments : exopod 1 bears 

 a single seta internally, and externally is armed with a long 

 spine that reaches as far as the base of the spine on the 

 succeeding segment ; exopod 2 bears a single internal seta, and 

 the external spine extends well beyond the base of the 

 proximal spine on exopod 3. On the posterior aspect are two 

 rows of small spinules, one row extends vertically down the 

 centre of the segment and the second runs horizontally along 

 the distal margin ; exopod 3 bears four setae on its internal 

 margin, and externally is armed with three teeth of more or 

 less equal size. On its posterior aspect, this segment carries 

 three curved rows of spinules. Terminally, the end spine is 

 broad and somewhat curved, having a finely-serrated outer 

 margin. 



The endopodite is two-jointed : endopod 1 bears a single 

 inner seta, and externally is produced at its distal extremity
