diameter and from PLE by nearly their radius. ALE and PLE 
contiguous as usual. Height of clypeus nearly equal to three times 
the diameter of AME. Chelicerae: general shape typical of males ot 
the genus; a series of teeth along near the lateral sides are, appar- 
ently, differently arranged on the right and the left; the right cheli- 
cera has a series of three teeth fairly clearly delineated in a row below 
the clypeal margin and probably two or three very minute cusps 
below those; on the left chelicera there may be three teeth but they 
are out of line; in place of the usually more or less conspicuous tooth 
near the promarginal row of teeth along the fang groove appears 
a group of minute cusps. Maxillae: typical of males of the genus 
except that teeth appear to be absent. Lip : as usual in the genus. 
Sternum: convex as usual; about as wide as long; extended between 
fourth coxae which are separated by a little less than their width. 
Legs : i = 423 in order of length ; other features typical of the genus. 
Palp: trochanter with a small, ventral protuberance; other features 
essentially as shown in Figures 24-26. Abdomen : typical of males 
of the genus. Color in alcohol : carapace a light yellowish brown with 
few darker streaks and with a. moderate amount of black pigment 
in ocular area ; sternum a light grayish brown ; mouth parts yellowish 
brown with variations ; legs yellowish with some variations ; abdomen 
a light grayish brown dorsally and quite grayish laterally and ven- 
trally where there are several darker areas and lines especially anterior 
to the genital groove. 
Female par atype. Total length 1.27 mm. Carapace 0. 61 mm long; 
0.42 mm wide; about 0.22 mm tall; not as steeply raised in cephalic 
region as in male holotype but posterior declivity is quite steep. Eyes : 
essentially as shown in Figure 27; ratio of eyes AME : ALE : 
PME : PLE = 3:5:5: 4-5- ALE somewhat angular. AME 
barely separated from one another; separated from ALE by nearly 
half their radius and from PME by nearly their diameter. PME 
separated from one another by nearly seven-tenths of their diameter 
and from PLE by half their radius. ALE and PLE contiguous as 
usual. Height of clypeus nearly equal to four times the diameter 
of AME. Chelicerae: general features typical of females of the 
genus; fang groove probably with five teeth on each margin. Max- 
illae and lip : general features typical of females of the genus. 
Sternum : convex as in male ; longer than wide in ratio of about 
16 : 13; otherwise essentially as in male. Legs: 1423 in order of 
length but with only small difference in lengths of first and fourth. 
Spines on palp but no claw observed. Abdomen: typical of females
