DESCRIPTION OF GENERA AND SPECIES. 207 
spine. The palp is highly developed in the digital bulb. The eyes resemble substantially 
those of the female. 
Disrrisurion: I have an immature male and female, collected from the neighborhood 
of Philadelphia. The female above described is from the District of Columbia, the male 
from Selma, Ala. (Marx Collection.) The spider as originally described was collected and 
figured by Abbot in Georgia, and it has further been observed in North Carolina, Florida, 
Virginia, and as far north as Connecticut. It thus appears to inhabit the entire Atlantic 
Coast from New England to Florida, showing a large elasticity of organism. It probably 
has a wide distribution throughout the United States. 
Genus CAREPALXIS L. Kocu, 1871. 
This genus is distinguished by a high and rounded corselet, steeply arched at the 
sides. The caput is a lofty conical elevation, rounded at the top, which towers aboye the 
crest of the corselet, the summit occupying about the middle point of the cephalothorax, 
whence it rolls downward to the fosse by a sharp declivity, and with a somewhat arched 
incline forward to the eye space., The face is distinguished by a forehead which projects 
far above the eye space, and is itself considerably higher than in the typical species, twice 
as high as the lower part of the face. Both eye rows are procuryed, and the side eyes 
placed low down upon the outer margins of the clypeus. The midfront eyes are separated 
from the sidefront by a space much greater than that which divides themselves, in this 
respect resembling Epeira. The legs are in order of length 1, 2, 4, 3, the first and second 
pairs almost equally Jong, and are without spines. The length of the maxillze equals the 
width, thus substantially resembling Epeira. The abdomen is cylindrical; about one-third 
longer than broad; clothed with soft skin; carried in a position almost perpendicular; the 
base has tubercles, whose summits in the typical species are divided into several peaks. 
The spinnerets are distal.

Femare: Total length, 3.5 mm., but from the peculiar manner in which the animal 
carries its abdomen, in a plane almost perpendicular to the cephalothorax, this length is 
deceptive ; cephalothorax, 2 mm. long, 1.5 mm. wide; abdomen, 3.3 mm. long, 2 mm, wide. 
CrpHaLotnorax: The corselet is hidden by the overhanging abdomen, somewhat 
rounded on the sides, truncated behind, smooth and sharply sloping to the base; the caput 
is extremely high, the forehead towering far above the eyes, having a height nearly twice 
as great as that of the face from the midrear eyes to the margin of the clypeus (Fig. 6b, 6c), 
giving the front thus a triangular appearance; the color is dull brown, covered with golden 
yellow hairs; the forehead has two knobs about midway between MR and the crest. The 
sternum is broadly shield shaped, rounded at the sides, bluntly rounded at the apex, covered 
with grayish yellow pubescence, dark brown, with lighter shade in the centre; the labium 
is bluntly triangular; the maxille gibbous, curved toward each other, somewhat longer than 
wide. : 
liyrs: Ocular quad on a high squarish prominence; the rear width greater than both 
the front and sides; eyes about equal in size; MF separated by 1.5 diameter; MR by at 
least two diameters. The side eyes are on slight tubercles placed far down on the side 
margin of the clypeus; they are equal in size, somewhat less than the middle eyes,
