AEANEIDEA. 
9 
The maxillce are strong, considerably bent towards the labium, over which their extremities 
almost meet, and broadly impressed across the middle ; their colour is rather darker than 
that of the cephalothorax. 
The labium, owing to some foreign matters adhering to it, could not he very distinctly 
seen, hut its form appeared to he oblong, rounded at the apex, and its colour like that of the 
maxillae. 
The sternum is oval, pointed behind, like the maxillae in colour, and clothed with grey 
pubescent hairs. 
The abdomen is about equal in length to the cephalothorax, of an oblong-oval form, 
not very convex above ; it is of a somewhat mottled clay-colour, with an oblong, brownish, 
dorsal marking on the anterior half of the upper side, produced behind into a narrow brown- 
pointed stripe: the fore-extremity of this dorsal marking is strongly suffused with rusty red 
brown. The middle of the upper side of the abdomen has four small red-brown impressed 
spots in the form of a square, whose fore-side is rather the shortest ; it is clothed, but not 
Very densely, with coarsish dark brown hair. The spinners are strong, those of the inferior 
pair being double the length of those of the superior. 
Hah. — Neighbourhood of Leh, August or September 1873. 
7 .— Drassus invisus, sp. n., PI. I, Pig. 6, ? . 
Adult female : length rather more than 5 lines. 
This spider is nearly allied to 1). interlisus, which it resembles in form, general colouring, 
structure, and appearance : it is however smaller, and the colour of the caput is much less 
rich, being but little darker than the thorax, which is a dull yellow-brown; the whole of 
the cephalothorax is covered with a sandy-grey pubescence; and there is a dark line 
running down the middle of the caput from the hind-central pair of eyes to the thoracic 
indentation. 
The eyes are also different in their position from those of 7). interlisus, those of the 
bind-central pair being placed obliquely to each other, and those of the fore-central pair 
nearer together and further from the laterals. 
The falces are less strong, and the apex of the labium does not reach so nearly to the 
extremity of the maxillae. . . 
The abdomen is of a rather short, oblong-oval form, tolerably convex above : it is of a 
dull-yellowish hue, thinly clothed with fine hairs : along the middle of the fore-half on the 
upper side, is a slightly darker, but clearly defined, oblong marking, which has its hinder 
Part tapered off to a sharp point, and an angular point on each side where the tapering portion 
begins. There are also four small dark blackish-brown oblique spots on the fore-half, 
forming a rectan-le whose length is about double its breadth : two fine parallel brownish lines 
run on°the underside from the genital aperture to a little distance from the spinners, and 
from each of the inferior pair of spinners a similar line runs a little obliquely to a point 
iu a line (in a transverse direction) with the termination of the two other lines just men- 
tioned : the spinners are short and strong, those of the inferior pair being the strongest 
a ud a little the longest : the genital aperture is small and of a very simple form. 
Bab.— Between Sirikol and Aktalla, between the 8th and 31st of May 1874.
