it is a modified bristle ; it is liorn-shaped, almost twice as long 

 as it is wide at the base, curved slightly forwards and placed 

 near the anterior margin. Tibia with two dorsal, one sub-dor- 

 sal, external, bristle, ail set on low tubercles ; processus 

 tibialis also articulated, similar in size and shapo to proces- 

 sus genualis, only slightly blunter at the top. Tarsus with 

 distinctly demarcated, very short basitarsus, only half as long 

 as it is wide ; at the démarcation-fissure it is slightly bent 

 downwards, tapering gradually towards the top, where it is 

 pointed (on latéral view) ; it has straight, finely pointed hairs, 

 varying in length from half to one third that of the telotarsus ; 

 two of tliese hairs are placed ventrally in the proximal th'ird, 

 3 to 4 dorsally and sub-dorsally ; behind the anterior one of 

 the ventral ones there is a strong, finely pointed bristle, bent 

 sharply forwards near the base, so as to run parallel with 

 the telotarsus. 



The ambulacres (fig. 82 &) bear a very remarkable resem- 

 blance to those of Trachygamasus Berl. (Berlese, 1906, 

 pi. 6. fig. 1) ; superunguinal lobes large, triangular, rounded 

 at the top ; at the base of the claws two short, curved, finger- 

 shaped, to ail appearance soft secondary claws ; subunguinal 

 slips narrow, lanceolate, larger than the superunguinal lobes. 



Female. 



The female is a little larger than the maie and differs 

 from it in the following respects : 



The epistoma (fig. 83) is a little narrower at the base than 

 in the female, with straighter edges, which hâve in the middle 

 two pairs of short and narrow, pointed teeth, set closely 

 together. 



The mandibles (fig. 84) are of exactly the same shape as 

 in the nympha (compare Trâgardh, 1910, fig. 94), with narrow 

 chela ; length to width as 53 : 20. The upper jaw is a httle 

 longer than the lower one, rounded anteriorly, with terminal 

 tooth ventrally excavated to receive that of the upper jaw ;
