to observe; both patella and tibia are short; both together only a 
little longer than tarsus; no tibial apophysis observed; no figures 
drawn because of obscurity of parts. Abdomen: essentially typical 
of males of the genus in general; with a weakly outlined, narrow 
dorsal scutum. Color in alcohol: quite typical of the smaller species 
in this genus. 
Female. Total length 4.28 mm. Carapace essentially as in male; 
median thoracic groove barely discernible. Eyes: essentially as in 
male. Other features very similar to those of male except for the 
sexual features. Epigynum: very obscure; with small openings 
close together and placed at some distance anterior to the genital 
groove; obscurity precludes significant representation in figures. 
Color in alcohol: very similar to that of male. 
I did not collect members of this species during my visit to St. 
Vincent, B. W. I. in October, 1966 and, apparently, it has not been 
reported since it was described by Simon. 
Trachelas jamaicensis Gertsch 
Trachelas jamaicensis Gertsch, 1942: 9, fig. 28. The female holotype from 
Jamaica, W. I. is in the American Museum of Natural History, New 
York City. Roewer, 1954: 587. 
One female from Jamaica, W. I., Portland Parish, Blue Mt. Peak, 
July 10, 1953 (W. G. Lynn) is referred to this species with some 
uncertainty.

Holotype. The male holotype is from Jamaica, W. I., Portland 
Parish, Blue Mts., Main Range, 5000-7000 ft. elevation, August 
17-19, 1 934 ; collected by Dr. P. J. Darlington, Jr. The name of 
the species is an arbitrary combination of letters. 
Description. Total length, including considerably extended che- 
licerae, nearly 7.67 mm; total length, excluding the chelicerae 5 6.69 
mm. Carapace 3.25 mm long; 2.73 mm wide opposite second coxae 
where it is widest; much elevated in cephalic region where it is nearly 
1.54 mm tall; median thoracic groove quite conspicuous with several 
shallow radiating grooves; somewhat swollen laterally at level of 
PLE; otherwise quite typical of larger males of the genus. Eyes: 
eight in two rows as usual in the genus. Viewed from above, anterior 
row gently procurved and posterior row moderately recurved and 
occupies slightly more than nine-elevenths of width of carapace at 
that level and is wider than anterior row in ratio of nearly 16 : 13.
