which has a pair of very minute and inconspicuous denticles. Side-plates 1-4 oblong, 

 rounded below, only the postero-inferior angles of 1 and 2 quadrate; postero-inferior 

 angle of 5 and 6 rounded, of 7 quadrate, but not produced. Pleon segments 1-3 each 

 with two dorsal procumbent teeth, no medio-dorsal carinal teeth, postero-inferior angle 

 of segment 2 with a small acute point, of three acutely produced, with two to three small 

 serrations and one larger tooth subapically on lower margin. Telson oblong, apex 

 truncate, slightly emarginate. 



Antenna 1, 1st and 2nd joints produced in two short denticles on lower apices, 

 flagellum7-jointed. Maxilla 1, palp slender, not reaching apex of outer lobe. Maxilliped, 

 2nd palpal joint produced on inner apex.

 d. Maxilla 1. e. 2nd joint of peraeopod 3. /. 2nd joint of peraeopod 5. 



Gnathopod 1 slender, chelate, 5th and 6th joints subequal, slightly longer than 3rd. 

 Gnathopod 2 slender, subchelate, 5th and 6th joints subequal, 6th slightly widening 

 distally to the rounded palm (as in figure of Iphimedia capicola, supra). 



Peraeopods 3 and 4, 2nd joint with upper and lower hind angles rounded, hind 

 margin feebly serrulate, with a slightly deeper indentation near lower angle, more 

 pronounced in peraeopod 4 than in 3. Peraeopod 5, 2nd joint with a wide semicircular 

 excision distally, hind margin serrate. 



Uropods 1 and 2 unarmed, uropod 2 slightly shorter than 1. Uropod 3 as long as 

 uropod 1, inner ramus longer than outer, ensiform, inner margin with a few widely- 

 spaced minute short spinules. 



Antenna 2 and distal joints of all peraeopods lost. 



Remarks. The excised 2nd joint of peraeopod 5, and the rounded apices of side- 

 plates 1-4 are the distinguishing features of this species, which as regards the mouth- 

 parts agrees with minuta (cf. Sars, 1895, pi. cxxxiii, fig. 1). This is the first record of 

 this genus in South African waters.
