only by a line. PME contiguous to one another for fully one-fourth 
of their circumference and separated from PLE by slightly more 
than one-fourth of their long axis. Height of clypeus a little less 
than one-fourth of the long axis of ALE. Chelicerae, maxillae and 
lip essentially typical of females of the genus with no observed spe- 
cial modifications. Sternum: very convex; nearly as wide as long; 
with a cluster of stiff hairs at bluntly rounded posterior end which 
is nearly opposite the proximal end of fourth coxae which are sep- 
arated by nearly their width. Legs: 4213 in order of length; well 
armed with spines; first legs with ventral and ventrolateral spines 
as shown in Figure 7 on tibiae and metatarsi; second legs essentially 
as in first but with ventral spines small and inconspicousus ; third 
and fourth legs with numerous slender spines on femora, tibiae and 
metatarsi less conspicuous than those on first legs. Palp: with 
numerous spines on four terminal segments much like those on Heter- 
oonops spinnimanus (Simon) (Figs. 8-9). Abdomen: ovoid; robust; 
with ventral scuta only weakly chitinized (Fig. 10) ; colulus appears 
to be represented by a pair of bristles; six spinnerets of moderate 
size and length. Epigynal area obscurely distinctive (Fig. 10). 
Color in alcohol: considerable pigment in ocular area with reddish 
tinge; nearly the whole body and appendages light yellowish with 
variations; abdomen reticulated with the angular areas of different 
sizes and shapes; the scuta are slightly more deeply yellowish than 
surrounding areas; just anterior to spinnerets, where darker bodies 
are often seen in many species, are a small pair of clusters of minute 
yellowish bodies. 
Diagnosis. This species seems to belong in the group of species 
including Oonops anoxus and Oonops vestus as described in Part 1 
of this series. 
Records. Four para, type females are now in the collection from 
the following localities in Puerto Rico: 5 km. from Mayaguez on 
Route 106; Montanas de Urojan; University campus; University 
farm east of Nuclear Center; all collected in January 1964. The 
male of this species is unknown.

Holotype . The male holotype is from Puerto Rico, W. I., El 
Yunque Biological Station, 2100 ft. elevation, January 25, 1964. 
The name of the species is an arbitrary combination of letters. 
Description. Total length 1.7 mm exclusive of the extended 
spinnerets; including the spinnerets, total length is 1.82 mm. Cara- 
pace 0.81 mm long; 0.62 mm wide opposite second coxae where it is
