Postero-inferior angle of 3rd pleou segment rounded. Antenna 1 half 

 length of body, 1st joint largest. Antenna 2 with ultimate pedun- 

 cular joint scarcely as long as penultimate. Inner plate of 1st maxilla 

 with 1 seta. Gnathopod 1, 5th joint shorter and broader than 6th, 

 which is narrow, oblong, inferior margin slightly concave, palm trans- 

 verse, defining angle quadrate, finger longer than palm. Gnathopod 2, 

 5th joint cup-shaped, 6th elongate ovate, narrowing distally, palm 

 concave but otherwise undistinguished from hind margin, a small 

 rectangular tooth at the finger hinge, palm and hind margin with a 

 few plumose setae, finger length of 6th joint. Neither 2nd nor 3rd 

 joints of both gnathopods are lobed at distal anterior apex. In ? 1st 

 and 2nd gnathopods i-esemble the 1st gnathopod of <$ . Peraeopods 1 

 and 2, 2nd joint strongly expanded, 4th distally lobed. Uropod 3, 

 peduncle with 2 spines on distal margin, rami subequal in size, outer 

 ramus with 2 hooked spines and numerous minute serrations on outer 

 (upper) margin. Telson small, subtriangular, 2 setae between the 

 lateral points.

Two specimens from Port Shepstone AVNW., distant 2 miles 

 (Natal). (24 fathoms. s.s. " Pieter Faure.") (S.A.M. No. 227), 

 present the following features : 



Both antennae lost. Eyes prominent. Inner plate of 1st maxilla 

 with only one seta. 



Side-plate 1 oblong, not produced forwards, 2 oblong, nearly twice 

 as deep as long, inferior margins of both setulose, with a tuft of longer 

 setae near the postero-inferior angle. 



First gnathopod, 2nd joint with prominent distal lobe, in <$ 6th 

 joint longer than 5th, stout, oblong, not tapering distally, palm a little 

 oblique, defining angle distinct but not prominent, palm sinuous, 

 concave near defining angle, convex near hinge ; in ? 6th joint not 

 quite so stout, palm a little more oblique ; finger strongly serrate. 



Second guathopod, 2nd joint with prominent distal lobe,. in <$ 6th 

 rather similar in shape to that of vaillantii but front apex not pro-
