Station 57. 



Two young females of this species were obtained off Wata 

 Mooli. The examples differ considerably from the adults, and 

 could scai'celj' have been identified without the aid of Haswell's 

 types. The pleopods furnish 

 excellent specitic characters, 

 which are probalily sufficient 

 to recognise this species by 

 at any age. The inner 

 ramus of the first pair is 

 twice as broad as long, the 

 outer rami of both the first 

 and second pairs are armed on 

 the outer distal border with 

 tenor twelve spines, together 

 with the usual plumose set;>^. 

 The outer ramus of the third 

 pair has a well-marked sutur- 

 al line. Both rami of the 

 succeedingpairs possess bran- 

 chial pleats, and the outer 

 I'amus of the last is pro- 

 vided with three small teeth- 

 bearing lobes, one at the 

 summit, another about the 

 middle of the apical part of 

 the lamina, and the third is on 

 the inner border below the 

 sutural line. The stylets of the male in Haswell's type are 

 broken off, they arise from the middle of the inner margin of the 

 ramus. The mandibles are moderate in size, the cutting edge is 

 thin and dentate, the inferior tooth is tridentate and attended by 

 an inferior bunch of cur\ed denticulate spines. Molar tubercle 

 well defined, and encircled with spinules. Palp consisting of 

 three subequal joints. First maxillse tipped with denticulated 

 spines. Second maxillee short, broad, and subequal in size. 

 Maxillipedes small, the superior setiferous lobes are well 

 developed, the third joint is much shorter than the second, fourth, 

 or fifth. The flagellum of the first antennae is ten-jointed, the 



First Pleopod.
