bases of fourth coxae which are separated by ten-sevenths of their 
width; third coxae nearly globose; others somewhat elongated with 
first longest of all. Legs: 4123 in order of length; with few spines; 
moderately long and slender; first tibia only a little longer than first 
patella. Palp: general features shown in Figure 2; tarsus much 
inflated with cymbium and bulb not clearly separated; femur mod- 
erately inflated. Abdomen: general features shown in Figures 3-5; 
scuta conspicuous and quite distinctive; division between epigastric 
and ventral scuta obscure; the narrow sclerite often partially sur- 
rounding the base of the spinnerets appears to be lacking here. Color 
in alcohol : carapace and sternum a rich yellowish brown ; legs and 
mouth parts somewhat lighter; abdominal scuta nearly like the cara- 
pace and sternum; abdominal areas not covered by scuta are a clear 
white. Short hairs are numerous over entire surface of abdomen. 
Records. One male paratype was taken with the holotype in the 
vicinity of the William Beebe Tropical Research Station, Simla, 
Arima Valley, Trinidad, W. I., April 25, 1964.

Holotype. The male is from St. Croix, U. S. Virgin Islands, 
September 23, 1966. The name of the species is a Latin adjective 
referring to the faint reticulated color pattern, poorly shown in the 
holotype but clearer in the female paratype. 
Description. Total length 1.56 mm, exclusive of the somewhat 
extended spinnerets; including spinnerets total length is about 1.65 
mm. Carapace 0.66 mm long; 0.54 mm wide opposite second coxae 
where it is widest; about 0.27 mm tall; moderately arched from 
PME along midline to beginning of moderately steep posterior border 
gently recurved ; surface very finely granulate. Eyes : six in two 
rows as usual; posterior row recurved (Fig. 6). Ratio of eyes 
ALE : PME : PLE = 7:6: 6.5. ALE separated from one 
another by about their radius and from PLE only by a line; PME 
contiguous to one another and separated from PLE by about one 
half their radius; with considerable black pigment in ocular area. 
Height of clypeus equal to a little more than the radius of ALE. 
Chelicerae: vertical; parallel; without special modifications; with 
numerous slender spinules; no teeth observed along fang groove but 
close observation impossible without injury to holotype. Lip: very 
obscure but apparently wider than long and with procurved distal
