Frmate: Total length, 11.5 mm.; abdomen, 9 mm. long, 2.8 mm. at the base, dimin- 
ishing in some specimens to 1 mm. at the apex; cephalothorax, 3 mm. long, 1.5 mm. wide; 
mandibles, 2.3 mm. long. 
CrrnALorHorax: Oval, squarely truncated at the base; fosse a triangular depression; 
corselet grooves and cephalic suture distinct; caput elevated above level of corselet; color 
brown, with yellow markings upon the caput, face, and sides, and slight grayish pubescence. 
Sternum yellowish brown, raised in the middle, a depression between coxs-I and II, 
scantily pubescent, with a line of long curved bristles along the concavely truncated base, 
extending towards the labium; the latter is roundly triangular, wide at the base, which is 
of a brownish color, the tip being yellow; maxille more than twice the Jength of the 
labium; widest at the tips, which are roundly truncated, pointed outward, slightly concave 
on the margin; the fangs when folded do not touch the maxillx. 
Eyes: Ocular quad on a rounded eminence most prominent in front; the rear width 
greatest and about equal to the length; MF somewhat larger than MR, separated by about 
or a little more than one diameter, MR separated by about two diameters. Side eyes upon 
small tubercles about equal in size, smaller than MF, separated by a space about one quarter 
greater than that which divides the middle group; space between MR and MF about twice 
the interspace of MF’; the space between MR and SR somewhat less than that between MR. 
Lees: 1, 2, 4, 3; uniform yellow in color, abundantly armed with small. aculeate 
bristles, and well provided with long blackish spines. The palps are colored and armed as 
the legs. The mandibles are long, strong, extended forward nearly horizontally from the 
face, almost straight or but slightly concave upon the exterior; about ten teeth on the 
superior claw furrow, of which two are on the apex of the mandible; color yellow, with 
long bristles, particularly upon the inner surface; fang dark brown, glossy, evenly curved 
on the exterior surface. 
Axspomren: About four times as long as wide; the dorsum slightly arched; in some 
specimens thickened, in others of almost uniform width throughout, and with but little 
curvature; dorsal surface beautifully reticulated, the skin in alcoholic specimens having a 
metallic golden lustre; the dorsal pattern is a central median line, with a cruciform figure 
near the base, and two curved longitudinal branches further down. The spinnerets are just 
under the apical wall. The ventral pattern is a lighter band of reticulated yellow. The 
epigynum is situated close up to the base, and is a simple arch without scapus. 
Mare: 10.3 mm. long, somewhat shorter and slighter in general form than the female, 
but in color and pattern closely resembling her. The corselet grooves and cephalic suture 
are less distinct; the midfront eyes are decidedly larger than the midrear; SF soméwhat 
smaller than SR. The legs are long, the first leg much longer relatively than the second; 
it is about eleven times the length of the cephalothorax. The mandibles are three to four 
mm. long, straight upon the exterior surface, and but little curved on the interior, which is 
marked by strong rows of long bristles; the teeth are small, those upon the interior furrow 
numbering about nine, with two additional and larger ones on the apex; a long spur curved 
and widely bifid, or with a short tooth below the point, mark the upper and inner surface 
near the apex. The fang is long and somewhat undulate towards the apex. The radial 
joint of the palp is nearly twice as long as the cubital. The jaws are slightly inclined to 
the face instead of being extended almost horizontally, as with the female. Banks says 
that the outer tooth (spur) is not bifid. This characteristic should, I think, be modified as 
above by speaking of the spur as “widely bifid,” or at least with a toothlike Projection 
upon the side near the apex. 
Disrrisution: My specimens are from New York, New Jersey, and Florida; Dr. Marx 
has a specimen from Texas, thus indicating a distribution along the entire Atlantic and 
Gulf Coasts.
