from in front, anterior row strongly recurved, posterior row moder- 
ately recurved in order to produce the characteristic placement. Ratio 
of eyes AME :ALE : :PME :PLE — i4:io::22:22 (measurements 
taken from borders of the corneas). AME separated from one an- 
other by about one third of their diameter, from ALE by slightly 
more than their diameter. PME separated from one another by 
about one third of their diameter, from PLE by a little less than 
their diameter. LE separated from one another by about twice the 
diameter of ALE (the corneas of these eyes are extended much fur- 
ther than usual). Central ocular quadrangle wider behind than in 
front in ratio of 10:7, wider behind than long in ratio of 25:22. 
AME separated from PME by a little more than one third of their 
diameter. Height of clypeus equal to about the diameter of AME. 
I he clypeus bears 17-18 long slender spines with one isolated on each 
side dorsal to the base of the cheliceral boss. 
Chelicerae. Nearly perpendicular, slightly divergent, moderately 
robust. Basal segment 2.275 mm. long. With many long slender 
spinules extending forward from promargin and many long, curved, 
light colored hairs at distal end. Basal boss well developed. Fang 
moderately robust, fairly evenly curved; with three promarginal 
teeth, the middle one the largest; with three retromarginal teeth of 
moderate size and gradually diminishing in size from near base of 
fang distally. 
Maxillae. Nearly parallel, moderately robust, only slightly concave 
in distal half along lateral border. Only slightly more than twice as 
long as broad. With well developed scopula along medial border to 
distal tip. Serrula only moderately well developed along distal lateral 
corner. With many long slender and stiff bristles especially along 
lateral border. 
Lip. Only a little longer than wide in middle; slightly concave 
along distal border; reaches only slightly beyond middle of maxillae. 
Sternal suture slightly procurved. 
Sternum. Subrotund; as wide as long; slightly pointed at posterior 
end which is not extended between fourth coxae which are separated 
by about one fifth of their width. Only slightly scalloped opposite 
the coxae. Moderately well supplied with slender stiff bristles. 
Legs. 1423. Width of the first patella at “knee” .845 mm., tibial 
index of first leg 6. Width of fourth patella at “knee” .780 mm., 
tibial index of fourth leg 8.
