T\iQ first pair (text-fig. 33 c) of legs is in most respects like that of E. cnrticauda; the process 

 on the anterior surface of Ri with 3 teeth, perforated by delicate canals, is almost obsolete; the Se of 

 Re I is fairly long and slightly swollen at the base; the pore in the outer margin of Re III is placed 

 distinctly nearer the base than the middle. The pes II shows a similar difference as that of E. curti- 

 cauda, with fairly well developed articulation between Ri I and II and comparatively short Se Re II. 

 The pes III — IV are like those of the females, but the inner margin of the second basipodite in the 

 fourth pair of legs is completely smooth. 



The fifth pair of legs (text-figs 33 b and e — g) shows most similarity to that of E. cnrticauda; the 

 right and the left legs are of almost equal length; the Ri dext., which extends almost to the end of 

 Re IinjII, is terminally inflated, and outwards has two rounded processes in the middle; the Re III is

slender, gradually attenuated towards the tip and is in distal half, in a similar way as in E. messinensis, 

 regularly serrated along the margin (text-fig. 33 e). The left leg has a long and slender Ri, which 

 extends to the end of Re I and terminally is rounded and slightly convex in its whole length; the Re I is 

 fairly long and slender, somewhat concave inside and here possessing a few protuberances; the Re II is 

 somewhat shorter, with a basal rounded process and 2 distal ones, of which the one is short and conical, 

 while the other is about one third as long as the segment, and gradually attenuated, the Re III, which 

 is distinctly half as long as the Re II and placed at the base of the last mentioned process, is trian- 

 gularly pointed beyond a distal conical process and hairy along inner margin proximal to it (text-

The shape of the body is like that of the adult, but the frontal keel is somewhat lower; the 

 lateral corners are rounded (fig. 5 h), not produced, and the fifth somite is dorsally as well as laterally 

 represented by a mere seam. The abdomen is about one fourth as long as the anterior division. The
