Crustacean Fauna of South Africa. 201 



An examination of the specimens, referred by Stebbiug in 1910 to 

 Maera bruzelii, and others from the same locality as the former, has 

 convinced me that they represent a new species, or at least a very 

 distinct littoral variety. 



Though at first sight they appear to resemble very closely M. bruzelii, 

 yet they differ in a number of characters : 



Side-plate 1 not nearly so much produced forwards, inferior margin 

 only very faintly serrate and only on posterior half, side-plate 2 not 

 serrate ; postero-inferior angle of 3rd pleon segment rather more pro- 

 duced than in Stebbing's figure of M. bruzelii (corresponding with his 

 description), but posterior margin not serrate; 2nd joint of mandibular 

 palp not bent ; inner plate of 1st maxilla with 3 apical plumose setae ; 

 inner plate of maxilliped with outer distal angle sharply produced ; 

 palm of 2nd gnathopod irregularly dentate, most of the teeth bearing 

 spines, one tooth near hinge and another near defining angle rather 

 larger than the rest. 



The 3rd-5th peraeopods are very much stouter than in any species 

 of Maera, and from M. bruzelii in particular they differ in having very 

 much broader 4th and 5th joints. 



First uropod with marginal spines on inner ranius only. 



Telsonic apices either rounded off subacutely, or with a minute 

 setuliferous notch on the apex and a similar one subapically on 

 either side, the inner one being further from the apex than the 

 outer. 



Further details are as follows : None of the peraeon or pleon seg- 

 ments dorsally dentate or setiferous ; eyes subrotund, 1st joint of 

 1st antenna rather shorter than 2nd, with a stout spine on lower apex, 

 flagellum ca. 50- jointed, accessory flagellum 9-jointed, equal to 2nd 

 peduncular joint ; gland-cone of 2nd antenna reaching almost to end 

 of 3rd joint, ultimate joint a little shorter than penultimate, flagellum. 

 shorter than peduncle, ca. 30-jointed ; 3rd joint of maudibular palp 

 subequal to 2nd, straight and sparsely setose. 



First guathopod very similar to that of M. bruzelii, palm minutely 

 serrulate. Both gnathopods in the ? similar to those of the $ , but 

 the 2nd is not so large. 



First and second peraeopods not strongly spinose or setose, hind 

 margin of 6th with 6 pairs of diverging spines. 



Third to fifth peraeopods, hind margin of 2nd joint straight in 

 peraeopods 3 and 4, slightly convex in 5, serrate in all, rounded 

 postero-inferior angle reaching nearly to end of 3rd, 4th strongly 

 expanded, 5th also expanded, but less strongly. 



Third uropods, ranii subequal, narrow lanceolate, apices tapering to
