matching palm, lower margin of 5th and 6th moderately setose ; the 

 right limb in the largest specimen is smaller and less developed than 

 the left one, having been perhaps regenerated. In $ 3rd and 4th 

 joints apically produced, 5th not produced, 6th longer than broad, 

 palm transverse, shorter than hind margin, setose, defining angle a 

 right angle but rounded, with one strong spine, finger matching palm, 

 spinulose. 



Pleopod 1, peduncle without setae, outer margins of therami evenly 

 convex, length of the rami a little more than twice as long as wide, with 

 surface sculpturing but only marginal setae. 



Operculum in $ tapering to a subacute entire apex. 



Uropods lost. 



Length : 7'5 mm. ; breadth : 2 mm. 



Colour : In spirit pinkish, eyes dark red. 



Locality : Lion's Head SE. i E., distant 50 miles (off Cape Penin- 

 sula). 230 fathoms. 2 <$ ; Cape Point NE. | N., distant 18 miles. 

 135 fathoms. 1 nonovigerous 9- s.s. " Pieter Faure." 2/4/02 and 

 27/2/02. (S.A.M. Nos. A4013 and A4121.) 



This species is superficially very close to S. dagama, but is distin- 

 guished by the difference in the ventral keels, the 1st joint of antenna 

 2, armature of the palm of peraeopod 1, the absence of the dense 

 covering of setae and the very acute apices of the 3rd and 4th joints 

 of the same peraeopod. The 1st peraeopod in the $ is also quite 

 different in the two species, on the presumption that the limb in 

 the single $ specimen of the present species has reached its full 

 development. 



STENETKIUM DIAZI n. sp. 

 (Plate XVI. Figs. 30-32.) 



Body with a few long scattered setae, chiefly on the lateral portions. 

 Antero-lateral angles of head acute, not incurved, teeth forming the 

 inner angles of the sockets for the second antennae somewhat blunt, 

 rostrum broader than long, antero-lateral angles subacute, anterior 

 margin slightly concave. Eyes reniform. 



First peraeon segment longer than 2nd, the antero-lateral angles 

 produced forwards to the level of the eyes, acute. Keel on segments 

 1-4 low, rounded, in each segment surmounted by a small acute 

 denticle, keel on segments 5-7 with the posterior angles in each 

 segment acutely produced. 



Pleon about as broad as long, lateral margin with a single tooth, 

 distal margin obscurely trilobed (as in occidental Hausen).
