[29 



The firs f pair (text-fig. 33 c) of legs is in most respects like that of F. curticauda ; 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 prs II shows a similar difference as that of E. ctirti- 

 catida. with fairl>- well developed articulation between Ri I and II and comparatively short Se Re II. 

 The pes ni~I]' are like those of the females, but the inner margin of the second basipodite in the 

 fourth pair of legs is completely smooth. 



The fi/fh pair of legs (text-figs 33 b and e— g) shows most siniilarit\- to that of E. ciirticaiidn ; the 

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

 Re I iNi II, is terminally inflated, and outwards has two rounded jjrocesses in the middle; the Re III is

 regularly serrated along the margin (text-fig. 33 e). The left leg has a hmg 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 i)laced 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-
