Marsupial plates overlapping in middle line, development in 

 internal pouches. 



First to third pleopods with 3 hooked setae on inner apex of 

 peduncle. 



Male stylet on 2nd pleopod narrow, longer than ramus, apex 

 acute. 



Fourth pleopod with outer margin of 1st joint of outer ramus 

 sparsely setose. 



Uropods in adult males extending slightly beyond, in females and 

 immature specimens as far as telsonic apex, inner apical angle 

 of both rami slightly prominent, outer distal margin of outer ramus 

 serrulate. 



Length : Largest $ 16 mm., 5 11 mm. ; breadth : $ 8 mm., 2 5 mm. 



Colour : Ground colour and markings rather variable ; head and 

 peraeon usually slaty, speckled with lighter dots, the 4th peraeon 

 segment with a median semicircular blue mark, open behind, the 

 process on 7th peraeon segment nearly white, continued in the male 

 as a light median streak on 6th and 5th segments ; telson rather 

 paler than rest of body, its borders distinctly paler, each with 2 

 dark greenish- brown patches ; uropods variously mottled with brown 

 and green with lighter speckles, the green usually forming a trans- 

 verse apical band on inner ramus and 2 apical patches on the outer. 

 The outer margin of the inner ramus and the inner margin of the 

 outer each have a semicircular transparent patch about the middle, 

 which when the uropods are expanded appear like a circular hole 

 through the uropods.

Types (2 $ $ , 3 ? ? ) in the k.k. naturh. Hofmuseum in Vienna. 

 The Natal specimen differs slightly in minor details from the 

 Cape specimens : the tubercles on the peraeon, except the two on 

 the 7th segment, are practically obsolete, on the other hand the 

 tubercles posterior to the two keels on the telson are rather more 

 numerous, the apical slit is proportionately wider anteriorly and 

 there is just a suspicion of a median tooth, the serrations on outer 

 distal margin of outer uropods very well marked. It measures only 

 8 mm. x 4 mm., although it is full grown; but in this connection 

 it may be mentioned that specimens from the east side of the
