Chickering — Genus Scaphiella 
141 
metatarsi. Abdomen: 1.05 mm long; .46 mm wide about one fifth 
of its length from posterior end where it is widest; considerably 
compressed laterally; ventral scutum reaches posteriorly for about 
two thirds of length of venter and extends dorsally to cover lateral 
surfaces but leaves nearly the whole dorsum uncovered; a very nar- 
row sclerite surrounds the spinnerets ventrally and laterally but not 
dorsally; spinnerets appear typical of the genus; openings of book- 
lungs and tracheal spiracles quite distinct. Epigynal area quite dis- 
tinctive (Fig. 2). Color in alcohol: all parts, except those abdominal 
areas not covered by scutum, are orange yellow with minor varia- 
tions; the unshielded areas are nearly white. 
Scaphiella barroana Gertsch 
Scaphiella barroana Gertsch, 1941: 10, figs. 20-22. Male holotype and 
paratypes of both sexes from Barro Colorado Island, Panama Canal Zone 
are in the American Museum of Natural History, N. Y. City. Chickering, 
1951: 234. 
One male taken January 28, 1958; one male taken May 15, 1964; 
twelve specimens all taken between 1941 and 1946 in a Berlese 
funnel by Dr. James Zetek constitute my entire collection of this 
species. Dr. Gertsch has loaned me two males; one taken in July, 
1938 and the other taken Nov. 1952-March, 1953 in a Berlese fun- 
nel by Dt. Zetek. All of these have been taken on Barro Colorado 
Island, Panama Canal Zone. The palpal features of the male seem 
to be fairly clear and quite stable. The epigynal area is less clearly 
defined and appears to be somewhat variable.

Holotype. The female holotype is from Jamaica, W. I., St. 
Catherine Parish, Guanaboa Vale, December 4, 1957. The name of 
the species is an arbitrary combination of letters. 
Description. Total length, including bases of chelicerae, 1.5 1 
mm. Carapace 0.57 mm long; 0.44 mm wide opposite second coxae 
where it is widest ; 0.2 mm tall ; nearly level along middorsal region 
from PME to beginning of posterior declivity opposite anterior bor- 
der of third coxae; posterior declivity with a concavity a little below 
the middle and with two long, stiff bristles at top; not notably granu- 
late. Eyes : six as usual in a compact group ; viewed from above, 
posterior row gently procurved. Ratio of eyes ALE : PME : 
PLE = 6.5 : 5.5 : 4.5. ALE separated from one another by a 
little less than half their radius (Fig. 3) ; ALE barely separated 
from PLE; PME contiguous to one another and to PLE. Height of
