Janira neglecta, sp. nov. 



Specific Diagnosis. — Body oblong-oval, somewhat narrow, rather less than 

 three times as long as broad ; cephalon with sides nearly straight, posterior angles 

 rounded, front very slightly convex between the bases of the antennules. Lateral 

 margins of all the segments of the peraeon straight or slightly convex, entire, quite 

 covering the coxal plates. Pleon oval, narrowing posteriorly, about as wide an- 

 teriorly as it is long ; margins sm.ooth, entire, posterior margin very slightly 

 produced between the bases of 

 the uropoda. Eyes large, of 

 numerous ocelli, Antennules 

 reaching to the end of the pen- 

 ultimate joint of peduncle of 

 the antennae ; first peduncular 

 joint broad, nearly circular; 

 second nearly as long, but much 

 narrower ; third shorter, hardly 

 distinguishable from the flagel- 

 lum, which contains about ten 

 joints. 



Antennae about as long as body; last two joints of peduncle subequal, with 

 smooth margins with a few fine setae ; the scale on the third joint narrow but dis- 

 tinct ; flagellum much longer than peduncle. First pair of legs (fig. 13a) with the 

 basos slightly longer than the ischium and as long as the carpus, merus only half as
