SECOND YARKAND MISSION. 
well-defined, transverse curved depression (or indentation); the convexity of the curve is 
directed forwards, and its ends merge in those of the thoracic indentation, which is a s 
curved (the convexity of the curve directed backwards) and deeply impressed ; these two 
curved indentations enclose a well-defined, somewhat roundish, smooth, and shining aiea , 
a portion of the surface of the caput on each side, in front of this, is transversely rugu ose, 
and, together with the rest of the thoracic surface, more or less, though not very tine ' . > 
covered with minute tubercular granulosities. 
The eyes are of moderate size and disposed in three transverse rows, 2, 2, 4, forming 
two widely separated groups, each group placed on a tubercular elevation. Those of e 
first, or foremost, row constitute one group close to the fore margin of the caput ; these 
appear to be rather the largest of the eight, and are separated from each other bv about an 
eye’s diameter ; those of the hinder group (consisting of the second and third rows) form 
narrow transverse elongate oval ; the eyes of the second row are also separated by an eye - 
diameter, and the length of the row is little, if anything, different from that of the hrs^, 
the hinder row is curved (the convexity of the curve being directed backwards); the eyes 
this row appear to be smaller than the rest, the middle pair being of an irregular form an 
yellowish- w T hite colour (the colour of the rest is dark), and considerably further from e 
other than each is from the lateral eye of the same row on its side, and the length ol 
line formed by those two, hind-central, eyes is a little greater than that of the seco 
(or middle row) . 03 - 
The legs are tolerably strong and of moderate length ; their relative length is 4, 1, > ’ 
they are of a bright yellow-brown colour, deepening into red-brown on the tibiae (an 
some other parts) of those of the first and second pairs; their armature consists of bans 
bristles, and spines, but neither of these in any great abundance. The spines are chiefly 01 * 
the tibiae and metatarsi ; those underneath the first and second pairs (particularly the A 1 ® ^ 
are the most conspicuous : the tibiae of the first pair are considerably but gradually enlaig e 
at their fore-extremity on the inner side, the enlargement terminating with a long, strong- 
curved, blunt-pointed spur or spine. A little on the inner side behind the base of this spim 
is a short and strongish denticulation ; the metatarsi of the first pair are rather abrup • ^ 
bent towards their fore-extremity, and slightly enlarged in a bluntish angular form on ^ 
inner side. The tarsi are devoid of any scopula, each ending with three claws ; those of t e 
upper pair are strong and pectinated ; the inferior one is small and inconspicuous. _ . g 
The palpi are long, rather strong, similar to the legs in colour, and furnished with ia V 
and bristles, those beneath the radial joint being the longest and most numerous. This 3011 
long, more than double the length of the cubital joint, and nearly equals that of 
tibiae of the first pair of legs ; it is of a rather tumid form, and is bent downwards near ^ 
anterior extremity, on the outer side of which there is a strong oblique indentation extent 0 
underneath, and margined above with a somewhat tuberculous ridge armed with short, s * lon ?^ 
tooth-like spines ; the digital joint is short, expanded laterally at its fore-extremity, w U ua j 
also somewhat indented, and armed with a few spines ; and the palpal organs are, as m s 
simple, though characteristic in detail, consisting of a roundish corneous bulb prolonged 
a long, tapering, slightly sinuously- curved, bifid spine, whose extremity, when im- 
position of rest, is directed outwards and backwards. inner 
The falces are moderately strong and bristly, and have near their extremity, on the 
side, a prominence, armed with strong tooth-like spines : their colour is similar to tna 
cephalothorax.
