médian line. Epigynialsliield large, almost twice as long as 

 it is wide at the base ; its posterior side is perfectly straight, 

 the sides convex ; it widens slightly on a level with the anterior 

 sideof coxae IV, and then tapers gradually, with convex sides, 

 towards the rounded top. Outside the posterior angles of the 

 shield there is a pair of hairs, similar to those of the sternal 

 shield. Theepigynial shield itself bears no hairs, as is also 

 the case in Urodinychus Kramerii. 



Ventral and anal shields so completely coalesced as to 

 leave no traces of any suture visible ; mth smooth surface. 

 Anal aperture small, situated close to the posterior margin 

 of the body. Near the posterior margin of the body 2 pairs of 

 hairs, and at the side of the anal aperture one pair, ail simi- 

 lar to those of the dorsal side. 



Metapodal shields large, distinctly demarcated from the 

 ventri-anal shield by a dark, slightly S-shaped line, which 

 runs from the inner posterior angle of coxae IV obliquely 

 backwards and outwards towards the margin of the body. I 

 hâve not been able to ascertain whether they reach the margin 

 or not. 



The parapodal shields with the same sculpture as the 

 marginal shields, viz. with rounded, depressed areas which 

 are deeper than in the former. 



The pleural ridges are not so distinctly set oiï, and, in con- 

 séquence, the foveolaepedales not so pronounced as in f/ro- 

 dinychus Kramerii, for instance. 



Stigmata small, on the posterior slope of the processi 

 metapleuri, on a level with themiddleof coxae II; from the 

 stigmata a post-stigmatic branch of the peritremata runs 

 straight backwards for a short distance ; the ante-stigmatic 

 part run outwards along the posterior side of the processi 

 metapleuri to their top, where it bends inwards along their 

 anterior side half-way to the edge of coxae II. 



Legs (figs. 137-140). 



Legs I are of the shape typical of the Uropodinae ; they
