Psyche 
[September 
Legs: 1243 in order of length; first leg most robust; no spines ob- 
served; cusps fairly numerous on first tibiae, metatarsi but only a 
few on first tarsi; also only few cusps on second tibiae, metatarsi and 
tarsi. Palp: essential features shown in Figures 7-8; apparently, the 
tibial apophysis is reduced to a short, blunt protuberance. Abdomen: 
in general typical of males in the genus; with a weakly chitinized 
dorsal scutum covering only the central part of the dorsum and with 
borders indistinct; the region anterior to the genital groove also 
weakly chitinized. Color in alcohol: closely similar to that of 
T . bravidus sp. nov. 
Diagnosis. For some time this species was regarded as a variant 
of T. bravidus sp. nov. but close comparison has convinced me that 
it must be regarded as a new species. The relationships of the eyes; 
the body size; features of the palp and several other somewhat 
obscure differences definitely seem to establish it as a separate species. 
Records. One male paratype was taken with the holotype but the 
female remains unknown.

Holotype. The male holotype is from Jamaica, W. L, Portland 
Parish, Hardwar Gap, Nov. 20, 1957. The name of the species is 
an arbitrary combination of letters. 
Description. Total length, measured laterally because of curled 
body, 6.7 mm; total length, measured dorsally as usual and including 
somewhat extended chelicerae, 6.5 mm. Carapace nearly 3.58 mm 
long (somewhat overlapped by abdomen) ; 2.55 mm wide opposite 
second coxae where it is widest; about 1.67 mm tall in cephalic 
region where it is tallest; with a well defined, short, median thoracic 
groove; 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 moderately recurved and 
occupies nearly seven-eighths of width of carapace at that level and 
is wider than anterior row in ratio of nearly 6 : 5. Ratio of eyes 
AME : ALE : PME : PLE = 9 : 10 : 8 : 9. AME separated 
from one another by slightly more than their radius and separated 
from ALE by a little more than their diameter. PME separated 
from one another by nearly twice their diameter and separated from 
PLE by a little less than 2.5 times their diameter. Lateral eyes 
separated from one another by nearly 1.4 times the diameter of 
AME. Central ocular quadrangle wider behind than in front in 
ratio of nearly 3:2; wider behind than long in ratio of nearly 5 : 4.
