Vijaya,* a. gen. 



Upper antennae in the male with the 1st joint of the flagelrum much longer than 

 any of the succeeding joints and very setose. 



Mandibular palp set on in the middle of the trunk. 



The remaining characters and the female antennae as in Amai^yllis, Stubbing, 

 '"Chall." Rep.,' p. 699. 



The curious difference in the male and female antennae makes a new genus 

 necessary. \ 



Vijaya tenuipes, n. sp. Plate [., tigs. 5. 



Coast of Ceylon, shallow water, 2 specimens, length 4 millims. 



Head very deep, rostrum small, bent downwards ; ocular lobe obtuse-angled. Eyes 

 very large, long-oval. 



Third pleon segment with the hind margin slightly convex, lower almost straight ; 

 the posterior angle acute, upturned, with a sinus above it, as in the other species of 

 this genus (fig. 5. pi. 8 ). 



Antennae in female subequal, reaching the bind margin of the 4th side-plates, 

 which are very large. 



Upper antennas (female) : 1st joint about twice as long and wide as the 2nd, 

 produced below in a distal tooth ; the 2nd the same proportion to the third ; flagelluni 

 considerably longer than the peduncle, the 1st joint resembling and rather shorter 

 than the 2nd, quite naked ; appendage barely reaching the end of the 1st joint of the 

 flagelluni ; 2-jointed, the 1st twice as long and wide as the 2nd (figs. 5. ant. 1 ). 



The upper antennce in the male hare the 1st joint of the flagellum its long as the 

 next three and densely setose on the inner side, both rlagella are broken, one at the 

 1 2th joint ; the appendage is 3-jointed, the 1st joint twice as long as the 2nd, which 

 is about in the same proportion to the 3rd : this is extremely narrow and reaches the 

 end of the 2nd joint of the flagellum (fig. 5. ant. 1 ). 



Lower antenna? : the 1st joint very short, the 2nd half as long again as the 3rd 

 (figs. 5. ant. 2 ). 



Maxillipeds : inner plates reaching beyond the middle of the palp, the ends cut 

 into 3 teeth, sides setose ; outer plates transparent, broad, reaching the end of the 

 3rd joint, dentate on the distal half, the indentations deeper towards the end. 

 Second joint of the pal}) rather longer than the 1st or 3rd, which are subequal. 

 Dactylus slender, with the inner margin finely denticulate and 2 or 3 setaB on the 

 point. 



First gnathopods : 1st joint as long as the remaining joints, about 5 times as long 

 as wide ; margins subparallel, 2nd longer than 3rd, which is irregularly triangular ; 

 wrist about two-thirds as long as the hand, with 3 fascicles of seta) on the hind
