process on the male palpus is much larger than is figured for 
O. tibialis and has two small teeth near the base and lacks the 
process on the cymbium. 
Through the courtesy of Dr. H. Dietrich of Cornell Univer- 
sity, I have been able to examine the holotype female and the 
allotype male of Oxyopes aglossus Chamberlin from Billy’s 
Island, Okefenokee Swamp, Georgia, collected by Dr. C. R. 
Crosby, June 1912. Figures (8, 10) are now given for com- 
parison of the epigynum and palpus of this species. Both differ 
from O. nelsoni. The epigynum of O. aglossus is very distinct. 
The median lobe has a truncate tip and below is a darkened 
transverse band that apparently connects the two sacs beneath 
the surface. The tibial apophysis of the male palpus does not 
project at right angles as far from the tibia as is shown in the 
original figure and on the ventral side there is a rather slender 
branch with an anterior tooth that is set at right angles to the 
tibia. The original figure was from the dorsal side and shows 
only the process and the interlocking process on the cymbium. 
It is not impossible that the figure was drawn from another 
specimen and may be another species. 
Family Theridiim: 
Genus Emertonella gen. nov. 
Cephalothorax low and flat, as wide as long, thoracic groove 
very short; eyes, both rows recurved, a.m.e. largest of the eight, 
lateral eyes touching; quadrangle of median eyes wider than 
long; clypeus higher than quadrangle; mandibles vertical and 
weak; labium wider than long; sternum as wide as long, pro- 
longed between fourth coxae in a truncate lobe; abdomen oval, 
dorsum thickened, venter with a large epigastric scutum that 
surrounds the pedicel and a large infra-mammillary scutum, 
both can be seen from dorsal side; legs , 4-1-2 -3, differing little 
in length; palpus with a short straight embolus, parallel to the 
conductor. Female unknown. 
Genotype: Emertonella emertoni (Bryant). 
The genus Emertonella differs from the genus Histagonia 
Simon, 1894, by the sternum extending between the posterior 
coxae, by a faint dorsal scutum and the well defined scutum 
around and anterior to the spinnerets; from the genus Paidisca 
Bishop and Crosby, 1926, by the faint dorsal scutum, by a large
