Figures 20-22 
Trachelas femoralis Simon, 1897: 883. The male and female syntypes from 
the Island of St. Vincent, B. W. I. are in the British Museum (Natural 
History), examined. Roewer, 1954: 587; Bonnet, 1959: 4667. 
Simon published only a very brief description of both male and 
female; no figures accompanied the description. I have had two pairs 
of specimens selected from the syntype series for examination. The 
following notes have been taken from one of these pairs. 
Male. Total length 4.4 mm. Carapace nearly 2.35 mm long; 
1.69 mm wide opposite second coxae where it is widest; nearly 1.06 
mm tall shortly behind PME where it is tallest; with continuous 
gradual descent to posterior border; with a short, moderately well 
developed median thoracic groove; surface finely pitted; slightly 
notched opposite first coxae. Eyes: eight in two rows as usual. 
Viewed from above, anterior row gently procurved and posterior 
row moderately recurved ; viewed from in front, anterior row moder- 
ately procurved and posterior row only slightly recurved, almost 
straight; posterior row wider than anterior row in ratio of nearly 10 
: 7. Ratio of eyes AME : ALE : PME : PLE — nearly 11 : 13 : 
13 : 12 (outlines somewhat indistinct). Central ocular quadrangle 
wider behind than in front in ratio of nearly 4:3; wider behind 
than long in nearly the same ratio. AME separated from one 
another by nearly their radius and separated from ALE by a little 
more than their radius. PME separated from one another by nearly 
1.33 times their diameter and separated from PLE by slightly less 
than their diameter. Lateral eyes separated from one another by 
nearly twice the diameter of ALE. Height of clypeus nearly equal 
to the radius of AME. Chelicerae: robust; with well developed 
basal boss; fang typical of the genus; fang groove with small teeth 
but exact number not determined because of fragility of the specimen. 
Maxillae: essentially as shown in Figure 20. Lip: about two thirds 
as long as maxillae; with two pairs of depressions near base (Fig. 
21) . Sternum: with a somewhat distinctive anterior border (Fig. 
22) ; longer than wide in ratio of nearly 55 : 43; with the usual 
conspicuous lateral margins and extensions; posterior end narrowed 
and nearly squarely truncated just anterior to bases of fourth coxae 
which are separated by nearly one half of their width. Legs: 1243 
in order of length ; first femora very robust ; second metatarsus some- 
what longer than first ; first tibiae, metatarsi and tarsi with a moder- 
ate number of the usual ventral cusps; second legs with few cusps. 
The palp is inconspicuous and its important parts are very difficult
