The characters by which the species may be distinguished, so 
far as I can gather them from the descriptions, are as follows :— 
Males. 
A. Carapace and abdomen clothed with plumose hairs. 
B. Carapace and abdomen clothed with simple hairs. 
I. Tibia i. and ii. with 9—10, protarsi with 8—9 long 
spines beneath on each side . 
II. Tibiai. and ii. with 4—4 long spines Deneath, pro- 
tarsi with 5—6. 
a. Anterior portion of ocular area almost vertical . 
6. Anterior portion of ocular area porrect, hori- 
zontal. 
1. Apex of lamina round the inner anterior por- 
tion of the bulb of the palpus much broader 
and more deeply and broadly bifurculate ... 
2. Apex of lamina round the inner anterior 
portion of the bulb of the palpus much 
narrower and less deeply bifurculate (simply 
Ditid and canaliculate) 22. <2. ........00.o0cc ees one 
Females. 
A. Carapace and abdomen clothed with plumose hairs. 
Ir Cane deeply striate, central stria oval-elon- 
gate; tarsi i. and ii. with 4—4, protarsi i. and ii. 
with 3—3 long spines beneath.. 
2. Carapace scarcely striate, central stria short, sub- 
punctiform ; tibia i. and ii. with 5—5, protarsi 
i. and ii. with 4—4 long spines beneath.. 
BG. Carapace and abdomen clothed with simple hairs. 
a. Legs very long; tibia i. and ii. with long spines 
beneath, 10 on inner side, 9 on outer side. 
a, The lateral lobes of the vulva bearing a rounded 
boss on the outer margin just behind the 
middle (see Keyserling’s figure) .. 
. The lateral lobes of the vulva without any 
rounded boss ........ 
6. Legs shorter, tibia i. and ii. with ‘only 4—4 or 
5—5 long spines beneath. 
aa. Tibia i. and ii. with 5—5 long spines beneath.

diameter apart, scarcely 1} diameters from 
the laterals ; anterior Eee of ocular area 
almost vertical aeaias 
. Posterior eyes moderate in size, , centrals over 
a diameter apart, at least two diameters 
from the laterals. Anterior portion of 
ocular area porrect ... 
oe au we i, and ii, with 4—4 long spines beneath. 
. Protarsi i. and ii. with 3—3 long spines 
beneath, besides lateral and apical spines... 
68, Protarsi 1. and ti. with 5—é long spines 
heneath, besides lateral and apical spines. 
a’. External sclerites of vulva eyenly rounded 
on their outer margin, sinuously concave 
on their inne. margin, their apices 
(anterior portion) sharp, with a minute 
cusp on their outer margin. 
b4, External sclerites of vulva emarginate on 
their outer sides, evenly convex on their 
ner margins, "their apices forming a 
broad hook, not very sharp at the point, 
without any minute CUSD.........000-00cee es
