DESCRIPTION OF GENERA AND SPECIES, Pages 
row is recurved, the rear row procuryed. The margin is swollen on either side of the 
median line, just above the insertion of the mandibles. 
Leas: 1, 2, 4,3; uniform yellow, without spines, but with abundant, long, aculeate 
bristles; the palps are colored and clothed as the legs; the mandibles are long, decidedly 
curyed, a warm yellow brown color, with three to four strong teeth, wide at the tips, which 
are tufted with long bristles, the fang long, narrow, and slim. 
Aspomen: An elongated oval, rounded at the base, narrowing to the spinnerets, which 
are distal. The dorsal field is yellowish brown in color, with longitudinal, reticulated bands 
of yellow along the margins, and a divided band of similar color along the median line. 
The skin is soft, reticulated, and covered with soft, short pubescence. The venter has a 
long, attenuated, yellowish band extending between the spinnerets, with blackish margins, 
and the epigynum presents an arched atriolum, without a scapus, but somewhat swollen in 
the centre. 
Mare: (Pl. XXVIII, Fig. 1.) In size, form, and color the male resembles the female. 
The abdomen is the same elongated oval, the length at least twice the width, relatively 
longer than with the female. The folium, as with the female, is marked by broad mar- 
ginal stripes of yellow on the side, bordered on either flank with interrupted lines of 
blackish, and in the centre a broken band of yellowish, reticulated color; the surface is 
strongly pubescent. The fosse is a longitudinal oval slit. The eyes (la) are upon a strongly 
elevated quad, the rear side of which is, relatively to the front, wider than with the 
female. On the clypeus is a diagonal ridge, extending about half way from the margin to 
the midfront eyes. The mandibles (1b) are long, convex on the apical half; the fang 
somewhat curved, uneven on the exterior surface, and a strong, black, triangular projection 
or tooth on the interior surface; close to the base of the fang is a very long, blunt, curved 
tooth. For palp see Fig. le. 
Disrripution: Philadelphia, New York, Texas (Marx). Doubtless widely distributed 
throughout the United States.

Frmate: In the Marx collection there is one female specimen, identified by Keyser- 
ling as of this species. Keyserling has distinguished it chiefly by the side outline of the 
mandibles (Plate XX VIII., Fig. 3). The specimen is 5 mm. long, and resembles P. brevis 
closely. The ocular quad appears a trifle wider in front than behind, instead of the 
reyerse, a8 in breyis; but I am inclined to think the two identical. 
Disrrisution: The species (or variety) has been collected in Philadelphia and the 
District of Columbia. 
No. 119. Pachygnatha Curtisi, new species. Plate XXVI, Figs. 5, 5a-b. 
Marx: Total length, 5 mm.; cephalothorax, 2.5 mm. long by 1.5 mm. wide; abdomen, 
3.5 mm. long by 1.8 mm. wide. General colors, dull yellow, mottled with black. The 
spinous armature of this species shows a marked difference from its congeners; but the 
characteristics are otherwise so distinctly of this genus that it is placed here. 
CrpHALorHorax: Cordate; the fosse a conical pit; corselet grooves distinct; cephalic 
suture well marked; color yellow, with streakings of blackish brown along the grooves, 
the suture, and on the base. The head is wide, quadrate, colored as the corselet, with 
lighter yellow in front. Sternum nearly as wide as long, covered with gray bristles, black 
along the margins, and muddy yellow in the centre. Labium subtriangular; less than one- 
half the height of the maxille, which are somewhat longer than wide; subrectangular in 
form, the tips roundly truncated, and wider than the rest of the organ.
