Epistome tapering proximally to a subacute apex, lateral margins 

 concave. 



Maxilliped, 4th-6th joints lobed, inner plate with 1 coupling-hook. 



Peraeopod 1, inner apex of 4th and 5th joints with 1, of 6th with 2, 

 stout apically bifid spines, inner margin of finger denticulate, secondary 

 unguis and seta well developed. Outer margin of 3rd joint of 

 peraeopods 2-7 with a few rather long setae. Inner margin of 4th-6th 

 joints of all the peraeopods furry, less so on 6th joint of peraeopod 7. 



Male appendages on 7th peraeon segment fairly stout, apically 

 blunt, their distance apart equal to the width of one of them. 



Pleopods 1-3 with 4-hooked setae on inner apex of peduncle. Male 

 stylet on pleopod 2 nearly twice length of ramus, tapering evenly. 



Pleopods 3-5 with 2-jointed outer ramus. Outer margin of outer 

 ramus of 4th and outer margins of both rami of 5th pleopod with short 

 regularly spaced setae. 



Uropods large, lamellate in g , inner ramus reaching just beyond 

 apex of telsonic process, outer ramus a little further beyond that, both 

 rami ovate, margins entire and non-setose. 



Length: 5' 75 mm. ; breadth (across peraeon segment 7) : 3 mm. 



Colour : Uniform greyish-white.

This genus is very well represented in South African waters, no 

 fewer than 10 species having been recorded ; the present paper adds 

 6 more. The value of the new material lies in the fact that in 4 cases 

 the d and $ could be definitely correlated. The specimens were 

 taken out of galleries and borings in sponges, as a rule only one <$ and 

 one ovigerous $ inhabiting each burrow. This is an exceedingly 

 valuable method of collecting and the sponges obtained on any expe- 

 dition should be thoroughly examined. Unless the <$ and ^ are 

 found together, it is next to impossible to correlate the sexes with any 

 certainty. 



For this reason it is greatly to be regretted that a fine <$ of Cilicaea 

 latreillei Leach was found in a burrow unaccompanied by its $ . The 

 sponge was a globular form of the genus Hircinia, and contained a 

 spherical chamber about 1 inches in diameter with an opening to
