Abdomen oviform, base I'oundly truncated, second half 

 dilated, pointed ; dull fuscous-black ; thickly studded with 

 small papillae ; hairs black, sparse ; ventral region light 

 olive-brown. Vulva reddish-brown, clouded with a deeper 

 tone ; triangular-obovate, moderately elevated ; transversely 

 rugose ; superior half occupied by two large sub-pyriform 

 fovese, divided by a wide rapidly dilated septum, bordered 

 by bead-like costse; shows two mussel-shaped indentations, 

 contiguous to costse. 



Single specimen. 



Fam. TETRAGNATHINiE. 



G-en. Tetragnatha, Latr. 



Tetragnatha quadri-notata, sp. no v. 



Fern. — Ceph. tb., long, 3-5 ; wide, 2'4. Abd., long, 5-2.; 

 wide, 3-5. Legs, 1, 2, 4, 3=193, 13, 11, 8 mm. 



Cephalothorax fulvous, ocular area lake coloured ; dorsal 

 band dappled with olive-brown, lake vein-like streiks ; bi- 

 crenate, fore-half much the widest, ends abruptly at fovea ; 

 encloses four large subpyriform, fulvous spots, first pair 

 encroach between dorsal and lateral eyes ; sub-marginal band 

 coloration of median. Some examples exhibit olive-brown 

 stripes in radiatmg depressions ; very sparingly furnished 

 with hairs ; pars cephalica depressedly convex, sides steep, 

 roundly truncated, eye- prominence moderately developed; 

 facial index exceeds lateral by one-fourth ; transverse sub- 

 oval fovea in centre ; pars thoracica broad ovate, rises above 

 plane of caput, posterior incline depressed ; fovea elliptical, 

 longitudinal, deep ; normal grooves somewhat shallow ; pro- 

 file-line ascends at an angle of 30deg. from dorsal eyes to 

 limit of caput, dips rather more abruptly to thoracic junction^ 



Eyes of moderate and nearly equal size ; posterior row 

 slightly procurved ; centrals less than one-third larger than 

 laterals, separated by an interval exceeding an eye's radius, 

 removed from side eyes by their breadth ; anterior row re- 

 curved; median pair visibly smpJler than laterals, rather 

 further from each other than they are from the latter pair — 

 an interval sensibly surpassing their breadth; lateral eyes 

 posited on a strong, common, dark tubercle, sub-touching. 



Falces yellowish mahogany ; sub-conical, base projects be- 

 yond plane of clypeus ; fore-third divergent, plainly longer 

 than the pars digitalis of palpus, fully as stout as the femur 

 of a fore-leg, retreat sensibly. 



MaxillcB ochreous-brown, pale apices ; spathulate, superior 

 angle rather prominent, inclined towards each other.
