extremely narrow, scarcely discernible outside oi^ peritrema. 

 Hairs, or better bristles, on venter small, numerous, about 

 15 pairs. Stigmata on a line between coxae III and IV. 

 Peritrema reaching the capitulum, becoming dorsal before 

 the shoulders (compare fig. 10). 



Epi s to m a (fig. 14) triangular, more or less unidentate, 

 yet laterally provided with two sharp teeth on each side, so 

 that it may be called quinquedentate. Markings on the dorsal 

 side ot basal piece, see figure. Sty li long. 



Mandibles not long, reaching when wholly retracted 

 the second jDair of dorsal rodlike hairs. Chelae (fig. 15) 

 rather long, with tibial and tarsal sense-organ. Before the 

 tibial sense organ an indistinct demarcation between tibia and 

 basitarsus. Upper jaw with 3 triangular incisors and three 

 long but low canines. Lower jaw with two small incisors be- 

 hind the end-incisor; three canines which have between them 

 still an indication of a smaller one, and a low blade-like 

 molar. P u 1 v i 1 I u m a row of hairs. 



Maxillae. Hyp osto m e (fig. 13) with the usual 4 

 pairs of bristles, usual horns and 14 transverse rows of minute 

 triangular dfmticulations in the median streak. The three 

 foremost of these rows are convex forward; the two hindmost 

 ones are concave toward each other. Between hairs 111 a pair 

 of triangular teeth directed forward and inward, like in the 

 protonympha (fig. 4). Demarcation between the anterior median 

 part and the sides very distinct, wavy. Inner malae consisting 

 in an inner long transparent slip and an outer fringed trans- 

 parent fan. Palps dorsally (fig. 10): in the middle of the 

 femur a hair which is curved inward and forward ; distally 

 and inward a transparent pin which is curved inward and 

 forward. Ven tr ally (fig. IG) the trochanter proximally and 

 inward with a toothlike chitiuous process ; before this a smaller 

 one; distally and inward a triangular transparent pin directed 

 inward and forward ; proximal bristle directed outward and
