Crustacean Fauna of South Africa. 259 



First gnathopod <$ , 2nd joint not apically lobed, inferior margin of 

 4-th and 5th subequal, anterior margin of 5th as long as 6th, 6th ovate, 

 palm oblique, straight, slightly concave near the blunt defining angle 

 which bears a spine, irregularly dentate, hind margin creuulate, both 

 with long setae, finger slightly overlapping palm, inner margin serru- 

 late ; in $ similar to $ but not so large, and palm a little more 

 convex. 



Second gnathopod <$ , 2nd joint not or only very slightly lobed on 

 front apex, 4th bluntly pointed, setose, inferior margin of 5th equal to 

 that of 4th, straight, finely creuulate, 6th longer than 5th, ovate, palm 

 oblique, concave, defining angle not produced, blunt, with a spine in 

 immature specimens but apparently without in adults, anterior and 

 hind margins of 5th and 6th densely fringed with very long plumose 

 setae in the adult, much less setose in immature specimens, finger 

 stout, tip closing on to surface of defining angle, inner margin serrate ; 

 in ? similar to $ but smaller, inferior margin of 5th not as long as 

 that of 4th, palm more sinuous, i.e. convex near hinge, concave only 

 near defining angle, 5th and 6th joints without the fringe of long- 

 plumose setae, being only sparsely clothed with simple setae which 

 are most numerous on the inferior margin of the 5th. 



First and second peraeopods, 2nd joint not expanded, similar to 

 those of Ampliitlioe rubricata (Mont.). 



Third peraeopod, 2nd joint not quite as broad as long, hind margin 

 smooth, anterior margin of 6th with 6 stout spines increasing in 

 length clistally. 



Fourth and fifth paraepods, 2nd joint half as long again as broad, 

 hind margin smooth, anterior margin of 6th with 6 stout spines, 

 increasing in length distally. 



First and second uropods, rami shorter than peduncle, outer a trifle 

 shorter than inner, both with 4-6 marginal spines, peduncle of 1st 

 uropod with 1 very strong apical spine. 



Third uropod, peduncle with ca. 10 very stout blunt spines on upper 

 apical margin, rami shorter than peduncle, inner with ca. 6 stout 

 spines on distal half of upper surface, apex with a group of setae, 

 outer ramus with 2 stout, blunt spines in middle of upper outer 

 margin followed by several setae, apex with 2 strong recurved 

 spines. 



Length: $ and ovigerous ?, 20 mm., one ovigerous ? 23 mm. 



Colour : Brown or greyish, with lighter spots on back, rather 

 irregularly arranged but usually one or two on posterior margin of 

 each peraeou segment, flagella of both antennae and 6th and 7th 

 joints of the peraeopods whitish, apex of 6th and 7th joints of 1st and
