from PLE by about one fourth of their diameter; PLE separated 
from one another behind by about four fifths of their diameter. 
Chitinized height of clypeus very low and irregular; membranous 
portion much higher. Chelicerae paraxial, parallel, porrect as usual 
in the genus; fairly robust; with a well developed supply of stiff 
bristles ; fang long, slender, evenly curved ; promargin of fang groove 
with a row of ten small teeth; along the obscure retromargin, as 
seen on a paratj^pe, is a row of about 7-8 very minute denticles; 
retromargin with a well developed scopula of long, slender hair or 
bristles. Lip and sternum : essentially typical of the genus. Legs : 
412 = 3; tibial index of first and fourth legs 11. Spines: all legs 
bear numerous spines essentially typical of the genus; special spines 
at articulation of first tibiae and metatarsi shown in Figure 7 ; the 
most ventral of the tibial spines is probably divided but the two 
parts are so closely apposed that they appear as one. Palp : essential 
features shown in Figure 8 ; bulb terminates in two spines. Abdo- 
men: typical of the genus; with a heavy coat of dark hair. Color 
in alcohol : as usual in the genus ; a unicolorous yellowish. 
Female paratype. Total length of female paratype, selected for 
description, from clypeus to posterior end of abdomen 4.03 mm; from 
anterior border of porrect chelicerae to posterior end of abdomen 
4.42 mm. Carapace 1.78 mm long; 1.32 mm wide; .45 mm tall; 
otherwise essentially as in male. Eyes: essentially as in male. Cheli- 
cerae: promargin of fang groove with nine small teeth; retromargin 
with about eleven minute denticles somewhat irregularly arranged ; 
otherwise essentially as in male. Lip and sternum : essentially typical 
of the genus. Legs: 4132; tibial index of first and fourth legs 12; 
spines on legs essentially as usual in the genus. Abdomen : typical of 
females of the genus ; with the usual heavy coat of hairs. Epigynum : 
with the usual swollen plate, typical of females of the genus. Color 
in alcohol : as in male. 
Type locality. Male holotype and female paratype selected for 
description taken at Simla, Arima Valley, Trinidad, W. I., April 
15th, and nth, 1964, respectively. Fourteen male paratypes and 
several dozens of what are believed to be females and immature 
specimens belonging to this species were taken in same general locality 
from March 31st to April 26th, 1964.
