fine simple setae, the outer with plumose setae ; apex oblique, 

 scarcely hollowed to receive the second joint, which is more than 

 twice as long as broad, with long plumose setae. Endopodite as 

 long as first joint of exopodite, outer margin strongly curved, with a 

 few setae becoming plumose distally, inner \ margin straight, apex 

 rounded. These parts are similar in both sexes. The penial fila- 

 ment of the male extends to the end of the endopodite, with which 

 it is fused for about one-half its length. The fused portion bears 

 very minute hairs, the free portion on outer margin (i.e., away from 

 endopodite) small setae at regular distances apart, and becoming 

 longer towards the apex, which is slightly bent over. In another 

 specimen the penial filament is a little shorter than the endopodite 

 with which only the basal third is fused. 



The Third Pleopod. Protopodite triangular with internal apical 

 tuft of setae. First joint of exopodite shorter and stouter than that 

 of the second pleopod ; length about li times its breadth, apex 

 oblique and slightly hollowed to receive the second joint, which 

 is 1^ times as long as broad, obovate. Endopodite reaching to the 

 middle of the second joint of exopodite, external margin very 

 convex, inner straight. Epipodite subtriangular, external margin 

 strongly rounded, inner slightly convex. Setae on the epipodite, 

 inner and proximal portion of outer margin of 1st joint of exopodite 

 simple, those on distal portion of the first joint and on the 2nd joint 

 of exopodite and apex of endopodite plumose. 



The Fourth Pleopod is very similar to the third, but apex of the 1st 

 joint of exopodite is less oblique and more hollowed out for the 2nd 

 joint, which is proportionately broader. Epipodite more semicircular 

 in shape. 



The Fifth Pleopod. First joint of exopodite larger than in any of 

 the preceding pleopods, proximally rather bulging ; breadth of the 

 2nd joint two-thirds its length. Endopodite does not reach the 

 middle of the 2nd joint, and the inner margin is convex. Epipodite 

 semicircular. 



The Uropods reach to the end of the telson, but not beyond. 

 Peduncle stout, twice as long as broad, grooved on its upper surface. 

 Both of the upper margins with 3 spines and a few smaller setae, 

 inferior margin with 4 spines increasing in length distally and 

 shorter ones at the apex. Inner ramus a little longer than the 

 peduncle, straight, upper margin with 3 spines in the middle and 

 one near the apex, as well as a few small setae, lower margin with 

 a small spine near the apex and 2-3 fine setae. Outer ramus not 

 quite as long as peduncle, upper margin with 2 spines and a few
