holotype from Barro Colorado Island, Panama Canal Zone, is in the 
Museum of Comparative Zoology, Roewer, 1954: 596; Bonnet, 1956: 
1210. 
In 1937 I had only the male holotype, two female paratypes and 
one additional male paratype. At present the collection includes sev- 
eral additional males and females all from the following localities 
in the Canal Zone: Barro Colorado Island, Fort Randolph and Fort 
Sherman and all were collected in June, July and August, 1936, 
1939 and 1950. Figure 17 represents a clearly outlined epigynum.

Corinna luteomaculata Petrunkevitch, 1925: 154, figs. 77-78. The female 
holotype from Cerro Flores, Panama is in the Peabody Museum, Yale 
University, Roewer, 1954: 598; Bonnet, 1956: 1213. 
This is another species which has not appeared in my collection 
from Panama and is still known only from the female holotype.

Panama Canal Zone, June, 1950. The name of the species is an 
arbitrary combination of letters. 
Description. Total length, including extended chelicerae, nearly 
7.86 mm. Carapace 2.93 mm long; nearly 2.20 mm wide opposite 
second coxae where it is widest; nearly 0.88 mm tall shortly behind 
PME and then slightly descending to beginning of posterior declivity 
opposite interval between third and fourth coxae; with a fairly well 
defined median thoracic groove. Eyes: eight in two rows as usual 
in the genus; viewed from above, anterior row moderately recurved 
and posterior row definitely procurved (Fig. 18). Central ocular 
quadrangle only slightly wider in front than behind; about as wide 
in front as long. Ratio of eyes AME : ALE : PME : PLE — 
nearly 11 : 8 : 9 : 8.5. AME separated from one another by slightly 
more than their radius and from ALE by slightly less than their 
radius. PME separated from one another by nearly their diameter 
and from PLE by nearly 1.3 times their diameter. Lateral eyes 
separated by nearly the radius of ALE. Height of clypeus nearly 
equal to the diameter of AME. Second row of eyes only slightly 
wider than anterior row. Chelicerae : robust ; much extended ; slightly 
divergent; teeth along fang groove not determined because of secre- 
tion and fragility of holotype. Maxillae : convergent but not meeting 
beyond lip; with well developed distal scopulae. Lip: slightly wider 
than long; slightly less than half as long as maxillae. Sternum: 
moderately convex; slightly lobed; nearly as wide as long; with an
