of the anterior margin of the lateral shields a pair of ditto. 

 On the first lateral sadden narrowing of the abdomen a short 

 pin. On the second one a long hair, as long as half the length 

 of the body, and directed rightly backward. On the top of 

 the abdominal lobes a pair of hairs ; these were absent in the 

 two specimens under my examination, but as far I could 

 conclude from the smallness of their rings of insertion, they 

 must have been shorter than the two other ones. On the inner 

 margin of the lobes there are two pairs of very short hairs, 

 one anteriorly and one posteriorly. Nephridial open- 

 ings on a level with the proximal ends of femora IV. 



Central side (Fig. 47). Epimera I united for two 

 thirds of their length to a sternum, reaching the line that goes 

 through the centres of trochanteres II. Epimera II as long 

 as epimera I, in their proximal two thirds quite straight and 

 parallel to the median line. The proximal end of the sternum 

 and the straight part of epimera II are united by a pair of more 

 interior and lighter-coloured epimerites slightly convex forward. 

 The margin of the body between the distal ends of the epimera 

 I and II is wide and strongly chitinized, especially the part 

 between trochanteres I and II, less the part behind trochanter 

 I. The ventrally sufïlexed lengthening of the dorsal prosomatic 

 dark chitinized margin is very wide anteriorly and sharply 

 pointed posteriorly so that they form a curve and high triangle 

 (compare with fig. 44 of the ç). Epimera III as long as 

 trochanter III, with distal external epimerite as wide as the 

 epimera themselves and reaching the edge of the body. Epi- 

 mera IV nearly one and a half times longer than trochanteres 

 IV, running nearly parallel to the median line, being proxim- 

 ally slightly curve inward, having here a short external 

 epimerite running toward trochanter III, and provided distally 

 with very wide but less chitinized epimerite with irregular 

 anterior and nearly straight posterior edge. There is a pair 

 of so called epimera IV, semicircular and surrounding the
