Pleopods rudimentary, lobe-like projections on lst-5th pleon 

 segments. 



Length: ? 15mm., <$ 4mm.; breadth: ? 9mm.; 1'5 mm. 



Colour: In spirit pale yellowish. 



Locality : Table Mountain 1ST. 79 E., distant 40 miles. 250 fathoms.

 1 ? , 1 3 s.s. " Pieter Faure." 18/4/00 and 11/6/03. (S.A.M. 

 Nos. A2274 and A2275.) 



Host: Plesionika in-art ia (M. Edw.). In the branchial cavities, both 

 right and left, chiefly the former, the males are attached sometimes 

 to the pleopods of the female, head hiiidermost, sometimes transversely 

 across the middle of the brood-pouch. 



In this species the uropods in the ? are more developed than 

 appears usual in this genus according to definition. Moreover, the 

 species hitherto described have all been taken from members of the 

 family Palaemonidae, whereas the host of the present species belongs 

 to the Pandalidae.
