SECOND YARKAND MISSION. 
and of a somewhat truncated appearance ; in the middle longitudinal line, the caput has a 
broadish ridge-like character, which runs far back to a deep transverse indentation at the thora- 
cic junction. Its colour is a rather rich yellow-brown, except the hinder part of the caput, 
which is paler, and its surface is granulose and covered with bristly hairs. 
The eyes are of tolerable size in two nearly equal transverse rows occupying the whole 
width of the fore part of the upper side of the caput. The hinder row is, as nearly as possi- 
ble, straight, the front row curved. The eyes of the hind-central pair are considerably nearer 
together than each is to the hind-lateral eye on its side ; the interval between the former 
being equal to a diameter, and that between the latter, to nearly two diameters. The eyes of 
the fore-central pair are seated on tubercles, and rather prominent, forming a line rather less 
than that formed by the hind-centrals : the intervals between the eyes of the front row appear 
to be as nearly as possible equal. The eyes of each lateral pair are seated, slightly obliquely? 
on a strongisli tubercle, and are contiguous to each other. The fore-central eyes form, as nearly 
as can he, a square, and the height of the clypeus (which is impressed below the eyes and 
prominent at its lower side) is more than half that of the facial space. 
The legs are moderately long, excepting those of the first pair, which are much the long 
est : their relative length is 1, 2, 4, 3. The first pair are strong, especially the femora, and, 
with those of the second pair, are of an orange-yellow colour, the fore part of the femora and 
tibiae being of a deeper and richer orange than the rest ; all are furnished with hairs and 
bristles, these of the first pair having numerous spine- like bristles, and a single longitudinal 
row of short, strongisli, somewhat denticular spines along the under side; those of the third 
and fourth pairs are of a paler hue than the others. 
The palpi are short, similar to the legs in colour, and (except the digital joint, which is 
large, reddish yellow-brown, and with its fore extremity considerably produced) slender; the 
cubital joint is "veiy short; the radial also is short, but spreads out at its outer extremity into 
a very laige and apparently bifid production : the palpal organs are well developed and pro- 
minent hut tolerably simple in structure ; with a slender curved filiform spine, and a small, 
straight, corneous process at their fore extremity; they are directed outwards, the convex 
sides of the digital joints being directed inwards. 
The falces are strong, of moderate length, and similar to the cephalothorax in 
colour. 
The maxilla are tolerably long and strong, much curved, and almost meeting over the 
labium, which is short and with a somewhat pointed apex. The colour of these parts is like 
that of the falces. 
The sternum is heart-shaped, broad, and truncate at its fore extremity ; it is of a rather 
orange-yellow colour, and its surface is granulose. 
The abdomen is short, considerably convex above, and projects well over the base of the 
cephalothorax ; looked at from above, it is of a somewhat heart-shape. It is of a yellow- 
brown colour, a good deal marked and spotted with white on the upper side ; these markings 
do not appear to follow any very distinct pattern, hut a more or less broken marginal band, 
most complete on each side of the fore part, and least traceable behind, may be seen. Four 
round red-brown impressed spots form almost a square a little in front of the middle, and 
across this part most of the white spots occur. 
This is in some respects rather an aberrant form of Theridion, but it is most nearly allied 
to T. pulchellum, Walck.
