carpus and propodus, whilst shorter pectinate setae are present at the distal ends of the 

 carpus and propodus. 



The protopodite of the first three pairs of pleopods is triangular with the produced 

 angle bearing plumose setae — three on that of the first and two on each of the second and 

 third. The suture of the exopod of the fourth pleopod is oblique, and its outer margin 

 is sparsely fringed with setae ; the endopod is rather small and broadly rounded distally. 



The uropoda (Fig. 8 c) are short and broad, and meet beyond the distal end of the 

 terminal segment. The protopodite has its inner angle produced into a broad triangular 

 lobe, at the apex of which is a single plumose seta ; the outer angle is also sHghtly pro- 

 duced and bears four delicate plumose setae on its outer margin. The endopod is not 

 much longer than broad, about twice as wide as the exopod, with a short inner margin 

 and with the distal portion broadly triangular in shape with rounded angles. The 

 exopod, which is considerably smaller, is oval in shape, with its distal extremity rather 

 pointed. The outer margin of the exopod, and the rounded distal end as well as the inner 

 margin of the endopod, are fringed with delicate plumose setae.
