Only the third leg of the right side is partly preserved; it is very thin, filiform, like in 

 the other species. 



Like in the genus Pontophilus the peraeopods of the 4 th and 5" 1 pair are of a much 

 stouter shape than those of the 3 rt ', but in this species these two posterior legs are subequal, 

 both as regards the length and the thickness of the joints. The legs of the 4 th pair (Fig. 75//) 

 project by the dactylus and two-fifths of the propodus beyond the truncated tip of the antennal 

 scale, those of the last pair only by half the dactylus. The merus, carpus, propodus and dactylus 

 of the 4 lh pair are respectively ó mm., 4 mm., 4,5 mm. and 1,7 mm. long, those of the 5 th pair 

 5,8 mm., 4,2 mm., 4,6 mm. and 2,1 mm. The upper border of the merus of the 4 th pair 

 terminates distally in a small spine and in both pairs there is a tuft of setae at the far end 

 of the propodi, but for the rest these legs are smooth and glabrous. Dactyli of the 4 lh pair 

 nearly two-fifths of the propodus, those of the 5 th slightly longer; the dactyli are nearly styliform, 

 hardly compressed, slender, tapering to the acute tip, with a tuft of short setae near the latter. 



The antepenultimate sternum is obtusely carinated in the midclle line anteriorly and 

 produced into a vertically compressed tooth or spine which, gradually narrowing, reaches to 

 the 2 nd joint of the anterior legs; the lateral margins of this tooth are slightly raised, so 

 that the surface appears a little concave ; the tip seems to be broken off and has perhaps 

 been acute. 



The outer branch of the pleopods of the i st pair (Fig. 75/) is 3,8 mm. long, one and 

 a half as long as the protopod, 3,2-times as long as broad in the middle, and fringed on both 

 margins with long, articulated, feathered setae; the inner branch, 2,7 mm. long and 6-times as 

 long as broad, is much shorter and, while the exopodite shows its greatest width in the middle 

 and narrows to both extremities, especially to the distal one, the inner branch shows nearly the 

 s a m e b r e a d t h a 1 o n g its w h o 1 e length, being only narrowed near the base and the 

 distal extremity is broad ly rounded; the margins are also fringed with long feathered setae, 

 which, however, are not articulated, but, besides these, the inner margin is moreover adorned 

 alono; its whole length with long', winding', flexible hairs that are not articulated 

 nor feathered. These long flexible hairs occur also on the inner border of the protopod 

 (Fig. 75/'), except in the middle, while this border is moreover fringed with long, feathered 

 setae. In the female of Sabinea septcmcariuata the inner branch is comparatively shorter and 

 the filamentous appendages much less numerous (C. Spence Bate, Report Challenger Macrura, 

 PI. XC, fig. ifi). 



In a full-grown, ova-bearing female, long 80 mm., of Saó. septemcarinata (Sabine) from 

 the Barents Sea, which was examined by me, the exopodite of the i st pleopod proved to be 9 mm. 

 long, the endopodite 5,2 mm., so that the latter was comparatively shorter than in Saó. indicci\ 

 the endopodite, 1 mm. broad, much resembled that of this species, but the distal extremity 

 decidedly narrows to the obtuse tip, so that the latter is not broadly rounded. 



The two branches of the 2 nd pleopod are of the same length, but the inner appears 

 in the middle a little less broad ; they have the usual lanceolate form, narrowing distally, and 

 both margins are fringed with feathered, articulated setae: the stylamblys (Fig. 75/', 75/) 

 measures nearly one-third the length of the inner branch, which is 3,4-times as long as broad
