Chick e ring — A canthoctenus 
85 
female allotype. Total length 15.08 mm., including the somewhat 
swollen bases of chelicerae; without the latter 14.625 mm. long. 
Carapace 6.1 1 mm. long, 5.20 mm. wide at interval between second 
and third coxae where it is widest; only slightly sloping from between 
PLE to about the middle of the well developed longitudinal median 
thoracic groove from which position it descends steeply to posterior 
border. 
Eyes. Arrangement as in male. Ratio of eyes AME :ALE : :PME : 
PLE = 14:12 ::20:23 (measurements taken from borders of corneal 
hypodermis). AME separated from one another by about five sev- 
enths of their diameter, from ALE by about 9/7 of their diameter. 
PME separated from one another by about their radius, from PLE 
by about their diameter. Laterals separated from one another by 
about the long diameter of ALE. AME separated from PME by 
the radius of the former. Central ocular quadrangle wider behind 
than in front in ratio of about 5 :3-5 ; wider behind than long in ratio 
of about 5:4.5. Height of clypeus equal to about 17/14 of the di- 
ameter of AME. Clypeus with about 12 long slender spines. 
Chelicerae. Nearly perpendicular; parallel, robust, moderately gib- 
bous in front; basal segment 2.6 mm. long. Basal boss well developed. 
With many stiff bristles in front. Fang and teeth along fang groove 
essentially as in male.

Trichobothria observed on many segments of legs and palps but their 
exact distribution has not been determined. Calamistrum short and 
near proximal end of fourth metatarsus. 
Spines. First leg: femur dorsal O-i-i-i, prolateral 0-1-1-0, retro- 
lateral O-i-i-O-i-i-i-O, ventral with numerous spines irregularly 
placed and difficult to describe significantly; first tibia with nine pairs
