Tlie posterior antennae consist of three nearly equal joints, and are furnished with one 

 or two marginal and a number of apical setae, two of the apical setae and one subapical 

 lieing strongly curved, long, and spiniform (PI. XIII. fig. 58). Mandibles stout, armed 

 with a strong terminal conical tooth ; serrate on l)oth edges, and a stout plumose spine ; 

 there are also two stout subapical plumose setre (PI. XIV. fig. 6). Maxillse broadly 

 subquadrangular, bearing one submarginal and a few terminal setie (PI. XIV. fig. 7). 

 The basal joint of the anterior foot-jaws is considerably dilated, and is provided with 

 two stout plumose spines on the inner distal angle ; the last joint is small, about once 

 and a half longer than broad, and Ijears four spines on its truncate ajjex (PL XIV. 

 fig. 8). Posterior foot-jaw stout, 3-jointed, the last joint very small and furnished 

 with a moderately strong and nearly straight claw and a long, spiniform, plain seta ; 

 the first joint bears three setse on its inner distal angle, and there are two setse near 

 the middle of the second joint (PI. XIV. fig. 9). Swimming-feet stout, 2-branched; 

 each branch consists of a single broadly foliaceous joint ; the outer liranch of the first 

 pair carries four stout dagger-shaped marginal and subterminal spines, serrate on both 

 edges, and three terminal plumose setae ; the inner branch carries three similar spines, 

 two plain apical setae, and a seta near the base of the inner margin. The second pair 

 of feet are like the first, but the three dagger-shaped spines on the inner branch are 

 replaced by plumose setae. Only two pairs of feet were observed ; the others wer(^ 

 wautiu!?. The last segment of the abdomen is about twice and a half lon<rer than 

 l)road. Caudal stylets very short, each bearing a long, slender, sabre-like spine and a 

 few very small setae.
