CHAMBERLIN: THE ARACHNIDA. 187 
together. Dorsal area of carapace between first and fourth trans- 
verse sulci with scattered small granules. 
The three anterior tergites of abdomen each with a transverse row of 
well-separated conical tubercles which decrease in size from the middle 
ones laterad. Anal tergite caudally rounded, with two rounded ele- 
vations near base. 
First two pairs of coxae curving a little forwards, the third straight 
throughout its length; second coxae a little longer than the third; 
first coxae with the usual row of setigerous tubercles which are very 
small; the second and third coxae smooth or nearly so. Fourth 
coxae greatly enlarged in the usual way; ending distally on the ecto- 
dorsal side in a large curved process which is unbranched, and on 
opposite side in a shorter one which presents a low rounded process 
on ectal side below tip. Coxae all with numerous small granules 
each bearing a hair. Spiracles distinctly exposed. 
First joint of mandibles immediately distad of its constriction with 
an abruptly elevated rounded hump. Second joint with a few hairs 
in front toward distal end. 
Trochanter of pedipalp with a rounded hump above and a single 
setigerous conical tubercle below. Femur subcylindrical; along ven- 
tral median line between base and middle three large conical tubercles. 
Patella unarmed. Tibia along mesoventral line with two spinous pro- 
cesses of which the anterior is much more slender and along the ecto- 
ventral line with two spinous processes of which the anterior is the 
larger, and in front of the latter a third much smaller spine. Tarsus 
along ectoventral line with five spines of which the first from caudal 
end and the third and fourth are larger; three spines in mesoventral 
line; claw large, as long or somewhat longer than the article (Plate 4, 
fig. 2). 
Femora of first three pairs of legs granulotubercular ventrally, the 
tubercles of the third pair largest; tibiae of these legs also tubercular, 
the tubercles small, those of the ventral surface and especially those 
of the third pair largest; metatarsi more obscurely granular. Tro- 
chanter of leg IV granular; on inner side with a rounded process and 
on outer side with a much longer acuminate process which curves 
back caudad above base; femur tubercular and distad with a number 
of larger processes of which two much exceeding the others in size 
arise from the ventral surface toward the distal end and distally 
curve mesad; patella uniformly seriately tubercular; tibia with 
numerous tubercles which are larger, subconical, on ventral surface; 
metatarsus over proximal half with numerous tubercles, the distal,
