black. Legs testaceous or yellow, the principal joints darkened at 

 extreme distal end. 



Chelicerae thick, very strongly bulging convexl}' forward at base 

 in front. 



Lateral eyes of each side connate, much farther from the median? 

 rhan the latter are from each other. Area of median eyes a little 

 longer than wide ; narrower in front than behind. 



Abdomen very high in front and projecting forward over cephalo- 

 thorax, rounded ; at caudal end projecting caudad of spinnerets in a 

 subconical, distally rounded process. General color relieved as usual 

 with the dull dorsal branching lines of ordinary type. A narrow 

 stripe between epigynum and spinnerets is of brown color, bordered 

 on each side by a bright silver-colored stripe. Sides darkened below, 

 dull, approaching midventral stripe in color. Spinnerets dusky. 



Epigynum strongly chitinized, transversely oblong. The dorsal 

 wall of the posterior opening divided by two long furrows as usual, 

 the median piece between exceptionally narrow, a little narrowing 

 caudad. 



Length of cephalothorax, 4 mm.; width, 3 mm. Length of ab- 

 domen, 9.5 mm. ; width at middle, 4.2 mm. 



Locality. — China: Soochow (N. Gist Gee). One female. 



Type.— C^t. No. 872, U.S.N.M. 



NESTICUS ALTERATUS, new species. 



Plate 4, fig. 28. 



Female. — Carapace and legs yellow. The latter without distinct 

 markings, though the joints are vaguely darker at ends, with trace of 

 paler subapical annulus. Abdomen above with a median longitudi- 

 nal dark line sending off branches from its sides. On caudal region 

 two transverse blackish bands continuous with vertical bands on the 

 sides. Venter mostly black, with, toward each side, two large in- 

 closed yellow spots which form a very conspicuous character. 



Clypeus higher than the ocular area. Anterior median eyes much 

 smaller than the others, close together, the area of median eyes being- 

 much narrower in front than behind. Posterior eyes also much 

 nearer to each other than to the laterals. The laterals on each side 

 contiguous. Anterior row of eyes nearly straight, the posterior 

 recurved. 



Labium as usual in the genus but a little more convex distally, the 

 border thickened, the plate being transversely depressed proximad of 

 this. 



Differing from most other species in having the abdomen sub- 

 cylindrical rather than globular. 



Epigynum very large and convexly bulging, with the opening 

 large (pi. 4, fig. 28).
