TETRAGNATHA. 43] 
1. Tetragnatha tropica. (Tab. XL. figg. 10, 10@-d, ¢; 11, lla, °.) 
Tetragnatha tropica, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 1], t. 2. figg. 3, 
3a,b(¢)'. 
Type 2, deuterotype ¢, in coll. Godman & Salvin. Total length, @ 12:5, ¢ 7 millim. 
Black eye-tubercles of the lateral eyes usually in contact, sometimes united only by a fine black line, rarely quite 
separate. Legs rather densely clothed with fine, erect, and some oblique, hairs, as well as with numerous 
spines, those on tibi i, and ii. being about three times the diameter of the segment. The mandibles of the 
male present the “ long tooth” on the upper margin of the fang-groove, and two adjacent teeth, a large 
and a small, at the apex beneath. 
Q. Abdomen distinctly gibbous above anteriorly ; fang armed with a short curved cusp at its base, on the 
dorsal side; the base of the mandible armed beneath with two teeth at the apex, and a series of ten 
teeth ; above with one large and one small tooth at the apex, and ten small teeth, the first of these being 
at least four times its own length from the apical teeth. 
Hab. Muxico, Atlixco (Godman), Orizaba, Tepetlapa, Cuernavaca (H. H. Smith) ; 
GuatemaLa, Menché (Sarg ').

6 a-d (Sd), 7, 7a, b (¢)*. 
Type 3, gynetype 2, in coll. Godman & Salvin. Total length, ¢ 7-9, 2 8-11'5 millim. 
Lateral eye-tubercles in contact. Legs clothed with fine, erect, and oblique hairs, as well as spines. Fang of 
mandible with a more or less conspicuous, dorsal, basal, marginal cusp; basal segment of mandible with 
the “large tooth” conspicuous ; a single small tooth beneath the “dorsal spur” near the apex, and 
another longer one still lower down, with a series of six or seven small teeth posteriorly ; the lower 
margin exhibits a small group of three teeth at the apex, the central one the longest, and a series of 
five teeth posteriorly. The tibia of the palpus is one-fourth longer than the patella; the cymbium 
attenuate and curved at its apex, vermiform; the conductor strongly geniculate in the apical third, 
folded over on the inner murgin and spoon-like at the apex; the embolus shorter, not reaching the apex 
of the conductor. 
9. Abdomen distinctly gibbous anteriorly ; the fang of the mandible having a dorsal, basal, marginal cusp ; 
the upper margin of the fang-groove with one long tooth towards the apex and a remote series of six fine 
subequidistant teeth; the lower margin with a small tooth at the apex and a remote series of seven or 
eight small subequidistant teeth, the first pair sometimes coalescent. 
Hab. Mexico, Teapa in Tabasco (Z7. H. Smith); Guatemata, Cahabon, Coban (Sarg, 
Champion *). 
3. Tetragnatha dentigera, sp. n. (Tab. XL. figg. 14, 14a-d, 2.) 
Type, ¢, in coll. Godman & Salvin. Total length 6°5 millim. 
Lateral eye-tnbercles in contact. Legs clothed with spines and fine hairs. The upper margin of the fang- 
groove of the mandible exhibits the “large tooth,” two smaller teeth on the apical side of it, that nearest 
to the large one being very broad and conspicuous, and six small teeth on the basal side; the lower margin 
bears two teeth anteriorly at the apex, and eight very minute teeth posteriorly. The conductor of the 
palpus is dilate at the apex (see figures) ; the tibia of the palpus twice as long as the patella; the cymbium 
neither bifid nor vermiform. 
llab. Mexico, Teapa (H. H. Smith).
