surface. The inetazonite is smootli dorsally. Poi-cs voiy 

 small, besriniiing on the sixtli zoiiite and located in cunlm-l with 

 and behind what lias to be considoi'ed as Ihc (ransvei'se suture. 

 No hni<>^itudinal suU-us is seen on a level with the pore. 



Last segment with postciioc uijirgin t'cehlv proiluced, cut 

 into a short and very wide angle, the rounded a])ex of 

 which covers the dorsal angles of the valves, though falling 

 short of the level of their posterior margins. Valves protruded, 

 rather flattened, naked and smooth ; mai'gins not compressed 

 and destitute of any pre-marginal sulcus, joining so as to give 

 rise to a distinct, sharp groove. Anal sternite with straight, 

 transverse posterior margin. Sterna of other segments covered 

 with fine, dense transverse wi-inkles. Stigmata sub-triangular, 

 small. 



Legs short, with one ventral bristle on each joint, except the 

 last, which bears two ; claw long, slender, acute, curved in the 

 anterior legs. 



Male : — Legs of first and second pair incrassate, but without 

 any special particulars. Coxjb of the legs three to seven tipped 

 with a feebly developed, thick, square [trotuberance (PI. xvi., 

 fig. 34). Tarsi not padded. 



Copulatory appendages : — Anterior gonopods (PI. xvi., figs. 

 85, 36) : ventral plate (V.) triangular, with upraised, sinuate 

 lateral margins and a notched summit. Tracheal stalk (fs.) 

 long and slender. Coxa angularly produced distad beyond the 

 end of the ventral plate, and endiiig proximally in a long 

 endoskeletic rod (ckJ,-.), as long as the tracheal stalk and of a 

 similar appearance. Femora (Fein.) fused, as usual with the 

 coxa along its entire inner maigin, concealed on the posterior 

 surface by the tibia (T.) which reaches as far down as the 

 root of the tracheal stalk and notably exceeds distally the apex 

 of the coxal expansion. 



Posterior gonopods (PI. xvi., figs. 37, 38) entirely independ- 

 ent, blade-like, slightly arched, with traces of articulation (.r.) 

 beyond its distal two-thirds, along the outer margin. Tlie inner 

 margin is lamellar with three tooth-like processes; one of them 

 (a.) stands about in the middle of the concavity, the second 

 (h.) opposite the trace of of articulation and the third (c.) more 

 triangular, beyond the second. Seminal groove (d.) short,
