CHAMBERLIN: THE ARACHNIDA. 223 
Sternum longer than wide in ratio 7:5 (Plate 12, fig. 3). 
Labium somewhat wider than long (nearly as 8:7); distad of proxi- 
mal third broadly, almost semicircularly rounded, but distally a little 
depressed, (Plate 12, fig. 6). 
Tarsi III and IV a little curved, I and II straight. Anterior 
tarsi not densely scopulate, the scopular hairs of tarsi III and [IV more 
sparse; metatarsi I and II with a few scopular hairs extending nearly 
to base, III and IV without any. Scopular hairs very broad and 
strongly clavate. Leg I with femur bearing two long spines in mid- 
dorsal line (between middle and base and middle and distal end 
respectively) and one on anterior surface between middle and distal 
end; tibia with three pairs of ventral spines; metatarsus with one 
subbasal pair. Leg II with spines same as those of I. Leg III with 
femur bearing three spines along middorsal line, two on anterior side 
and two on posterior side; patella with a spine on anterior and also 
one on posterior surface; tibia on ventral surface with a pair of spines 
at distal end and two single ones in line more proximad, two on ante- 
rior and two on posterior surface, and one subbasal one on dorsal 
surface; metatarsus on ventral surface with a distal pair and three 
(or four?) more proximal ones rather irregularly arranged, a spine at 
distal end on each side and dorsally a median distal one, a submedian 
pair and a single subbasal one. Leg IV with femur armed with three 
spines along middorsal line, two on anterior side and one on posterior; 
patella with a spine on anterior and one on posterior side; tibia with 
two pairs of dorsal spines, the anterior spine of each pair much smaller 
than the caudal one, ventrally with one distal pair, a submedian pair 
and a single subbasal spine; metatarsus with two pairs of dorsal 
spines, (between middle and base and middle and distal end respec- 
tively), three on anterior side and two on posterior, on ventral surface 
with two at distal end, one toward middle and one toward base. Claw 
of leg I with seven long teeth, (Plate 12, fig. 7). 
Inferior spinnerets widely separated, more than their diameter 
apart; spinning tubules very large, arranged in a semicircle. 
Spermatheca large, broadly fusiform, densely chitinized and dark 
in color, showing distinctly through surface integument, the openings 
small. The integument over the spermatheca in type is torn so that 
its precise configuration cannot be made out, but its modifications 
seem to be very slight, (Plate 12, fig. 8). 
Female. Length 6.2 mm. Length of cephalothorax 2.5 mm.; 
width 2 mm.
