this character, the presence or absence of apical apophyses on 
the tibia of the first leg of the male, may be given specific value. 
Sasonichus arthrapophysis, n. sp. o. 
(Pl. xv, figs. 2 a-b). 
Locality.—Barkul in south-east Orissa. 
Dimensions.—Carapace 7°5 X 6°0 mm.; sternum 2°7 X 2°5 
mm.; legs in the order 4, I, 2, 3. 
The patella and tibia of the first legs are together equal to 
the length of the carapace; the tarsus and metatarsus are together 
slightly shorter, and the femur is shorter still, the femur and 
half the patella being about equal to the length of the carapace, 
as are also the femur of the second legs with the whole of the 
patella, the tibia and metatarsus together of the third legs, and 
the patella and tibia together and the metatarsus alone of the 
fourth legs. 
Colour.—Dark brownish above, paler below, the ends of the 
tibiae of the legs silvery above—least so on the hind legs. 
Structure.—The carapace is ovate, slightly broader behind than 
in front. ‘The ocular area is very compact and is situated on a 
clearly defined tubercle approximately circular in outline. The 
anterior lateral eyes are oval, and are situated obliquely in front of 
the rest about a short diameter away from the anterior medians 
and fully a long diameter from one another. The anterior medians 
are round, their diameter fully as great as the long diameter of 
the anterior laterals; they are separated by a distance about 
equal to a diameter of the small posterior medians. The posterior 
medians and anterior laterals form a square; and the centres 
of the former are directly behind the outer margins of the 
anterior medians. The posterior laterals are quite as long as 
the anterior laterals, but much narrower. A line of low tubercles 
extends medially from the ocular tubercle to the fovea, which is 
linear as a whole, but distinctly recurved just at its extremities. 
Lines of tubercles radiate from the fovea. The whole carapace 
has probably been covered with long golden brown hair and 
scattered black spines, but most of these have disappeared. The 
spines are very long and thick posteriorly, where they project 
outwards and curve forwards. 
The labium is very imperfectly separated from the sternum. 
It is armed behind the anterior margin with a line of four more or 
less distinct erect teeth, among long spiniform hairs. 
The steynum is covered with erect spiniform hairs, and is 
bordered laterally and behind by a single row of long black 
slender spines. The coxae, trochanters and femora are similarly 
armed; but long white silky hair surrounds the mouth, both on 
the labium and on the coxae of the palps. On the latter it 
hides a group of denticles like those which form a line on the 
labium, but much more numerous.
