of the described males listed above. Its epigynum is very obscure and 
some other features seem to leave its status as very uncertain; for 
these reasons it is not included in this study. Another female from 
St. Augustine, Trinidad, W. I., April, 1964 is omitted from this 
study for about the same reasons. 
Trachelas bicolor Keyserling 
Trachelas bicolor Keyserling, 1887: 440, fig. 15. The female holotype from 
Haiti, W. I. is in the Museum of Comparative Zoology, examined. 
Banks, 1903: 340; 1909: 158 ; Petrunkevitch, 1911: 522; (not T. bicolor 
Pet, 1930) ; Lutz, 1915: 100; Bryant 1933: 192; 1940, 443, figs. 224, 233, 
235 ; 1948: 439; Roewer, 1954: 587; Bonnet, 1959: 4666. 
In 1940 Miss Bryant described the male of this species from Cuba. 
In 1948 she reported a male and an immature specimen from the 
Dominican Republic. 
Trachelas borinquensis Gertsch 
Trachelas borinquensis Gertsch, 1942: 9. The female holotype is from 
Aibonito, Puerto Rico, June 1, 1915 and is in the American Museum 
of Natural History, New York City. 
Trachelas bicolor Petrunkevitch, — 1930: 108, fig. 90. 
Apparently, Dr. Gertsch regarded this species as somewhat closely 
related to T. bicolor Keyserling. I have one female of this species 
from Puerto Rico, Maricao, Monte El Estado, January 9, 1964.

Holotype . The male holotype is from Jamaica, W. I., Portland 
Parish, Hardwar Gap, November 20, 1957. The name of the species 
is an arbitrary combination of letters. 
Description. Total length, including extended chelicerae, 3.96 
mm; total length, excluding extended chelicerae, 3.3 mm. Carapace 
nearly 1.48 mm long; 1.23 mm wide opposite interval between second 
and third coxae where it is widest; nearly 0.75 mm tall in cephalic 
region where it is tallest; otherwise essentially typical of males of 
the genus. Eyes: eight in two rows as usual in the genus; viewed 
from above, anterior row gently procurved and posterior row mode- 
rately recurved and occupies nearly the entire width of carapace at 
that level and is wider than anterior row in ratio of nearly 3 : 2. 
Ratio of eyes AME : ALE : PME : PLE = nearly 10 : 11.5 : 
9.5 : 11. AME separated from one another by nearly three-fifths of 
their diameter and separated from ALE by nearly four-fifths of their 
diameter. PME separated from one another by nearly 1.5 times 
their diameter and separated from PLE by slightly more than twice
