Legs. 



Of legs there are nineteen or twenty pairs. Apparently 

 there are usually nineteen in the male and twenty in the female. 

 I have found one male, however, with twenty legs. In the female 

 the legs at the posterior end of the body are, as a rule less widely 

 separated than those at the anterior end In the male this 

 feature is less pronounced. 



The crural grooves, or openings of the coxal organs, are 

 usually conspicuous on all the legs except those of the first ?nd 

 of the last two pairs. In several specimens, of both sexes, the 

 margins of the grooves are revolute at their distal ends, formmg 

 thick, white, R-shaped lips. 



Owing perhaps to the somewhat contracted condition of the 

 majority of the specimens, I have found it impossible to detect 

 the papillae observed b}^ Evans in connection with the crurai 

 grooves. The apertures of the crural glands are visible in one 

 individual only, a male. In this example a single, prominently 

 exserted, white papilla, bearing the orifice of the gland at its apex, 

 is found at the base of the two pre-genital appendages (pi. 

 xxxiv, fig. 7). 



The pads on the sole of the limb are of the usual crescentic 

 shape and are closeh^ covered with fine setae. On the last pair 

 of legs there are only two pads, both small and rudimentary ; 

 on the penultimate there are three. On all the remaining legs 

 there are four pads. On appendages in the anterior and middle 

 portions of the body the papillae of the first transverse row below 

 the proximal pad, though not fused together, are often trans- 

 versely elongated and are beset with fine setae in all respects 

 similar to those of the pads fpl. xxxiv, fig. 6). This row of 

 papillae thus constitutes, in effect, a fifth pad of a rudimentary 

 character, incomplete and much narrower than those which form 

 the true sole of the appendage. 



The renal apertures on the fourth and fifth pairs of legs 

 are found in the third pad counting from the base of the claw. 

 On these limbs the pad in question is completely divided into 

 two portions, and near this division at the end of the longer and 

 anterior of the two portions of the pad the renal orifice is situated 

 (pi. xxxiv, fig. 6). 



The foot (pi. xxxv, tigs. 3, 4) is similar to that of Eoperipdtits. 

 On either side of the curved claws is situated a single primary 

 papilla: one papilla be ng, therefore, anterior and one posterior. 

 The papillae are conspicuous in dorsal view by reason of their large 

 size and each is furnished with a slender apical spine. Behind 

 the papillae the lower surface of the foot exhibits four extremely 

 slight elevations, two, on each side, each bearing a few longish 

 setae (pi. xxxv, fig. 4); a lateral view ot" the foot consequently
