TRICLARIA.—AGELENA. 175 
corners of the base of the coxal joints (of the fourth pair of legs), which are contiguous at this point. 
Colour pale yellow. 
Abdomen oval, somewhat truncate before, moderately convex above. Colour brown, with an indistinct dull 
yellowish marking along the middle of the fore part of the upperside, broader at the hinder than at the 
anterior extremity, and somewhat trifid behind. The abdomen is densely clothed with longish prominent 
fine hairs. The underside is of a paler colour than the upper. 
Hab. GuateMAata, Rokminha (Sarq). 
Mr. Sarg notes of this spider, that with others of the species it was observed on the 
face of the rocks in and along the borders of a river, and that when disturbed instead 
of running up the rocks they ran across the water as if they were on dry land. It was 
not easy to capture them, and when this was attempted the spiders defended them- 
selves, biting their captor with a slightly irritating effect. Mr. Sarg speaks of the 
legs as being of a dull yellow-ochre colour, and faintly banded with brown. This 
habit of taking to the water corroborates the affinity, evidenced by the structure, to 
Dolomedes. 
AGELENA, Walckenaer. 
Agelena nova, sp. n. 
Adult male, length 2? lines. 
Cephalothorax of normal form, yellow-brown in colour, margined with a black line, and with a broad well- 
defined lateral band on each side of a darker yellow-brown, crossed by curved converging lateral blackish 
lines marking the position of the normal indentations. 
Eyes in the normal positions. The fore-laterals largest, the fore-centrals smallest. The quadrangle of the 
four central eyes is as long as broad, but narrowest in front. The interval between the hind-central pair 
is less than a diameter, and between each of them and the lateral eye on its side about a diameter» 
that between the fore-central pair is less than half a diameter. The height of the clypeus is greater 
than half that of the facial space. 
Legs moderately long, subequal, 4, 1, 2, 3, furnished with hairs and slender spines. Colour similar to that of 
the cephalothorax, the tarsi being rather paler. They are annulated, most strongly on the femora, with 
dark brown, the tarsi and metatarsi being immaculate. 
Palpi rather short, pale yellow-brown marked with blackish; the radial and digital joints darker yellow- 
brown. The humeral joint has two strongish spines in a longitudinal line on the upperside towards the 
fore extremity; the cubital joint has a single longer one. ‘The radial joint is stronger, and double the 
length of the cubital; it has a strong, somewhat bent, hollow and truncated apophysis rather on the 
outer side of its hinder extremity, and within the hollow there are some bristly hairs and a strongish 
spine ; there is also at the fore extremity rather underneath on the outer side a shorter, strongish obtuse 
apophysis, with a corneous point at its extremity underneath; on the inner side of the joint, in a 
longitudinal line, are also two long, strong, tapering spines. The digital joint is large, broad-oval, its 
fore extremity rather pinched in and a little produced; it is clothed with strong hairs and several spines, 
less strong than those on the radial joint. Palpal organs moderately complex, compact. 
Falces long, strong, straight, vertical, similar to the cephalothorax in colour. 
Mawille rather short, broad, truncated at their extremity on the outer, and rounded on the inner side. 
Colour yellow-brown. 
Labium broader than high, broadest at the apex, where it is squarely truncated. Colour dark yellow-brown. 
Sternum broad-oval, hollow-truncate before ; its posterior extremity produced into an obtuse point between 
the coxee of the fourth pair of legs. Colour yellow-brown, suffused strongly with blackish-brown on the 
sides, and with some indistinct converging lines of the same colour. 
Abdomen somewhat oblong in form, broadest at its hinder extremity ; yellow-brown marked with blackish,
