AUSTRALIAN OPILIONES 65 
Body. Eyemound rounded apically, but rising directly from the 
carapace, smooth, slightly canaliculate, set three times its diameter 
from the anterior margin of the carapace. Cephalothoracie сата- 
pace sclerotic, uniformly and finely granulate; sloping steeply 
down in front of the eyemound and extending up behind the 
eyemound to form a pair of large humps, between which there is a 
further sharp median ridge (Figs. 1, 9), rising in height but 
narrowing in width posteriorly to form a sharp peak jutting over 
the first tergite. Openings of the stink-glands clearly visible on 
the lateral margins of the carapace above coxae I. Abdomen soft, 
segmentation distinguished only by means of transverse rows of 
small setae and bands of dark-brown. Genital operculum squat, 
extending to posterior margin of coxa II. Mouthparts as in Fig. 
2. Maxillary lobes of coxa II relatively broad, sub-triangular, 
twice as long as width at base. 
Chelicerae. As in Fig. 9. Three times the length of body, both 
segments uniformly and strongly denticulate. Basal segment 
gradually narrowing from the proximal region but becoming 
stouter at the distal extremity. Second segment slender proxi- 
mally but becoming uniformly stouter distally until twice as wide 
as the base of basal segment. Fingers well developed, crossing at 
tips when closed. Fixed finger with one strong tooth on the inner 
surface at one third and a further similar tooth at almost three- 
quarters, followed by a few smaller teeth. Movable finger with a 
strong tooth at halfway, followed by a number of small teeth on 
the distal third. 
Pedipalps. Slender, almost as long as body, without apophyses. 
Tarsal claw small, pectinate below with a single row of 11-12 small 
even teeth on the proximal half (Fig. 4). | 
Legs. Coxae smooth, without granules. Femur with a prolateral 
row of sharp, fine, widely spaced small denticulations and a retro- 
lateral row of similar but much smaller denticulations. Femora 
II-IV with four rows of small dentieulations. Remaining seg- 
ments free from denticulations. Tibia ILI with nine and tibia IV 
with two false articulations.
