propodus are deep, compressed, and strongly carinate on the 

 upper and lower margins, externally convex and smooth, the 

 inner side is excavate and a little tumid in the middle. The 

 lower carina of the propodus is thickened behind, and defines 

 a groove on the outer side. The palm is longer than the car- 

 pus, proximally slightly deeper, it tapers a little, it has a few 

 small fascicles of hairs near the lower border, and near the 

 upper margin is a row of pits carrying hairs, its lower margin 

 bears a fringe of rather long hairs springing from just inside 

 the margin — the lower anterior angle of the carpus also has 

 a tuft of hairs — a short ridge extends from about the middle 

 of the immobile finger backward for a short distance. The 

 fingers are about half as long as the palm, sharp overlapping 

 at their apices with a small hiatus when in that position, the 

 mobile finger is without teeth and bears some fascicles of hair 

 above and below, the immobile finger has a tooth about the 

 middle, with a few denticles proximally from it. 



The following two pairs of legs are rather short, com- 

 pressed, and stout. Of these the first has the palm of the 

 propodus very short, and the fingers, when closed, have no 

 hiatus or teeth, the limb is setose on the m.argins of the joints. 

 The carpus of the second pair is distally broad, w^th a tuft 

 of long hairs on its posterior angle, and a fringe on the distal 

 margin, the propodus is subtriangiar and compressed, its outer 

 surface bears many hairs in fascicles, as also does the small, 

 compressed dactylus. 



The next two pairs of legs are longfer and slenderer, 

 reaching forward to the base of the maxillipcds, in the first 

 of these the coxa is very much expanded, the propodus is 

 compressed and thin, but not much expanded, and with the 

 dactylus is very setose. The last pair is subchelate, the pro- 

 podus and dactylus bearing an elegant brush of hairs. 



The sternal aspect shows the coxse of the first three 

 pairs of pereiopods close together in the middle line, but 

 the fourth pair are separated by an apparatus which is best 

 shown by the figure, the fifth pair are wide apart. 



The first two pairs of pleopods are more or less rudi- 

 mentary or modified in the female — especiallv the second — 

 to carry the esiSfs, the three following pairs are strongly deve- 

 loped and foliacious. 



The uropods are not so large as in other species of the 

 genus, the outer ramus is large and subtriangfular, capable 

 of folding beneath the inner ramus its inner border when in 

 that position, extending some distance under the telson : it 

 has a submarginal curved ridge, which extends from the 

 outer margin about half way across the surface, this and 

 the distal margin are thicklv clothed with short hairs.
