JANIRA CAPENSIS, n. sp. 

 (Plate XX. B.) 



Body nearly parallel-sided, greatest width in the middle, covered 

 with small slender spines which are strongest on the lateral margins 

 of the peraeon. 



Head, anterior margin somewhat produced, straight in centre, 

 slightly concave in front of the eyes, which are large, oval, black, 

 near the lateral margin. Peraeon, antero-lateral angles of the 

 segments produced as small spiniferous lobes, side-plates 1-4 

 bilobed, side-plates 5-7 extending beyond postero-lateral angles of 

 the segments, notched. 



Pleon nearly circular, lateral margins minutely denticulated, 

 surface spiniferous, about 7 rather long slender spines on lateral 

 margin and a row of close-set spines at the apex between the uropods. 



First antenna reaches to apex of 5th peduncular joint of second 

 antenna, basal joint of peduncle strongest, 3rd joint shorter than 

 2nd, 4th joint very small, flagellum 1^ times length of peduncle, 

 17-jointed, setose and with sensory filaments. 



Second antenna longer than body, exopod on 3rd joint well 

 developed, with apical tuft of spines, 5th joint rather shorter than 

 6th, Hagellurn a little longer than peduncle, multiarticulate, rather 

 feebly setose. 



Upper lip a little broader than long, apex rounded, with short 

 fine setules. 



Lower lip, lobes broad and stout, outer margin very convex, 

 inner apical angles setose. 



Mandibles, cutting-edge with (4 or) 5 teeth, secondary cutting-edge 

 in the left mandible similar, spine-row with 6 spines in the left, 8 in 

 the right mandible, palp 1st joint shortest, 2nd joint longest, with 

 a row of ca. 7 spines near apex, 3rd joint gently curved with 

 marginal and apical spines. 



First maxilla, outer plate with ca. 9 spines, most of them serrate 

 on their inner margins, inner plate half as wide as outer, apex 

 rounded, with 4 strong spine-setae and numerous setules.
