(Fig. 49) longer than wide, constricted in the middle to 

 receive in its excavations the coxae II, posteriorlv slightly 

 concave, provided with the usual 3 pair of hairs. Genital 

 shield long, sack-shaped, rounded anteriorly, not lyino- here 

 on the sternal shield, even not touching it ; its sides straight 

 somewhat divergent backward ; posteriorly truncate, with 

 slightly rounded angles, provided with the usual pair of hairs 

 posteriorly. No ventral shield. Anal shield of the 

 usual shape and ])ro})ortions, with the usual 3 hairs and 

 cribrum. Peritrematic shields rudimental, scarcely 

 observable as minute triangles behind the stigma. Stigma 

 about the level of the middle of coxae IV. P e r i t r e m a 

 nearly straight forward, becoming dorsal above trochanter II 

 and ending behind coxa I. Hairs on venter longer than on 

 dorsum, about 7 pairs in number. Posteriorly quite on the 

 edge of the body but still ventrally two longer bristles. 



Epistoma (Fig. 50) triangular, with scarcely rounded 

 top and with a hyaline margiu. 



Mandibles short, when wholly retracted reaching the 

 sternal shield. Chelae (Fig. 51) so far as I could observe, 

 even with immersion, without sense-organs ; it is, however, 

 possible that they were mutilated during the extirpation of 

 the mandible. Upper jaw (distal half of tibio-tarsus) with a 

 small incisor behind the long and nearly straight top-incisor, 

 then a sidewards implanted long tooth with 3 blunt and 

 rounded points, thus imitating a molar, then two blunt and 

 rounded dog-teeth ; no molars. Lower jaw (telotarsus) with 

 one incisor and one lono- not hio-h dog-tooth. 



Maxillae. Hypostome (Fig. 52) curious by the shortness 

 of the inner malae, which are half as long as the rather 

 slender and convergent horns and which miss any fringe or 

 lacininae. P a 1 ]> s (Fig. 53) ventrally : trochanter with two 

 bristles, femur with one bristle outward and one flat, truncate 

 hair inward ; genu with a flat, distally rounded hair inward,
