The genital aperture is very minute, being of a transverse narrow-oval form divided longitu- 
dinally by a septum.

This spider is nearly allied to both the foregoing species, but may easily be distinguished 
by the following characters. The general hue is less grey than in T. sabulosa , and the 
darker markings on the abdomen are more distinct ; the normal longitudinal marking on the 
fore half of the upper side is of a dark brown hue, with some black spots and markings on 
its outer margins : there are also some black spots alternating with the pale spots on the 
hinder half (these latter spots not being so white as in T. sabulosa). The under side of the 
abdomen is jet-black, distinctly and abruptly enlarged laterally from near the middle to the 
spinners, and there is a distinct short black bar on each side near the base of the spinners. 
The legs are unicolorous, having no trace of the black suffusion underneath the fore 
extremity of the tibise, except very slightly beneath those of the fourth pair. 
The eyes of the fore-central pair are smaller than in either T. sabulosa or T. propinqua ; 
and a striking character, which distinguishes it at a glance from both, is the dense clothing of 
scarlet (somewhat squamose) hairs on the front of the falces. 
It is probably also a smaller spider than T. sabulosa, though this is not certain, as the 
only example examined was not adult. 
Sab. — Murree to Sind Valley, between July 14th and August 15th, 1873. 
107. — Trochosa lhgtjbris, sp. n. 
Adult male : length nearly 5 lines. 
The cephalotliorax is of a dark, rich red-brown colour, thickly clothed with silky, light 
grey hairs disposed in a broad longitudinal and narrower marginal bands, — the sides being 
clothed with black hairs, forming thus alternate bands of white and black hairs ; the caput 
is considerably produced, and constricted on the lateral margins. The height of the clypeus 
is no more than, if quite so much as, the diameter of one of the fore-central eyes. 
The eyes are in the ordinary position ; the length of the front row is perceptibly longer 
than that of the middle row, whose central eyes are larger than the laterals, though much 
smaller than those of the hinder row ; these last are rather smaller than those of the middle 
row, and form a line very nearly indeed equal to that formed by each of them, and that one of 
the middle row on its side ; the interval between those of the middle row a little exceeds a 
diameter ; the eyes of the hinder and middle rows thus form very nearly a square whose 
interior side is the shortest. 
The legs are tolerably long and strong, though rather attenuated at their extremities. 
They are of a yellowish, dark red-brown colour ; the femora being much the darkest, and 
clothed with grey hairs, not only of a pubescent nature, but also with numerous long, slender, 
Prominent ones like those on the legs of Tegenaria and Argyroneta. They are also armed 
With strong spines ; the tarsi are furnished underneath with a thin scopula. Their relative
