obscurely distinctive (Fig. 4); scutum continued to region shortly 
above the pedicel; with two short spinnerets partly surrounded by 
a narrow, chitinized wall. Color in alcohol : carapace, sternum, 
chelicerae and lip all a rich, reddish brown; other mouth parts and 
legs considerably lighter with variations among them; first pair of 
legs and maxillae darkest; abdomen with dorsum almost black; venter 
nearly the same with faint lighter dots; genital region and scutum like 
sternum. 
Type locality. The female holotype and a single immature indi- 
vidual were taken on Virgin Gorda, British Virgin Islands, August 
21, 1966.

The name of the species is an arbitrary combination of letters. 
Male holotype. Total length 4.81 mm (cephalothorax and abdo- 
men considerably separated). Carapace 2.05 mm long; 1.56 mm 
wide opposite second coxae where it is widest; .99 mm tall; nearly 
level along midline from PME to beginning of steep posterior de- 
clivity opposite second coxae; posterior declivity very steep through 
dorsal half and then more gradual to posterior border; with a con- 
spicuous median pit at bottom of steepest part of declivity; surface 
finely granular; with a fairly well developed coat of procurved hair. 
Eyes: eight in two rows as usual; positions essentially as described for 
other species in this genus (1941, 1966). AME circular; all others 
oval with minor irregularities (Fig. 5). Ratio of eyes AME : 
ALE : PME : PLE = 12 : 10 : 11 : 8 (long axes used when 
eyes are not circular). AME separated from one another by about 
their radius, from ALE by about 2/3 of their diameter. Laterals 
separated by slightly less than 1/3 of the diameter of ALE. PME 
separated from one another by nearly 1/5 of their diameter, from 
PLE by a little more than 1.5 times their diameter. Central ocular 
quadrangle a little wider in front than behind and longer than wide 
in front in ratio of about 4:3. Height of clypeus equal to nearly 
three times the diameter of AME; ventral border grooved and with 
a narrow membranous margin. Chelicerae: typical of the genus; 
teeth and spines along fang groove essentially as described for O. 
macleayi Banks (1941). Maxillae typical of the genus. Lip: longer 
than wide in ratio of about 21 : 19; sternal suture line clear but, 
apparently, not permitting movement. Sternum : surface conspicuous- 
ly granular but reduced along the central region; conspicuously
