. Carapace about half the length of the anterior tibia and about equal 
to that of the fourth leg ; eyes of posterior line nearly straight, medians 
about a diameter apart and at least a diameter and a half from the 
laterals ; ocular quadrangle square ; eyes of anterior line straight when 
viewed from the front, the medians about a diameter from the laterals, 
less than that from each other. Legs strongly spiny : the first about 
eight times as long as the carapace. Abdomen about twice as long as 
wide, convex above, rounded in front ; obtusely angular above the 
spinners. Vulva consisting of 2 smooth shining heart-shaped sclerite, 
the apex of which is directed posteriorly. | 
&. About as large as the Y which it resemblesin colour. _ Mandibles 
longer, divergent, upper margin of fang-groove armed with a distal 
and a basal tooth with some smaller granuliform teeth between them ; 
lower margin armed, with 5 subequally spaced teeth, of which the 
basal is large and quadrate: fang strong, sinuous but not toothed. 
Palpi with short patella, this segment only about twice as long as broad 
and about one-third shorter than the tibia ; the two together scarcely as 
long as the tarsus and palpal organ, the spiniform process of the tarsus 
short, curved ; tip of organ ending in a short slender black spine. 
Measurements in millimetres.— @. Total length 10°5; length of carapace 
A: of first leg 31. ¢. Total length 10; length of carapace 4°5, of first leg 39.

The genus Orsinome is allied to’ Argyroépeira, but has no serially 
arranged bristles on the femora of the posterior legs. It ranges as far 
to the east as Celebes, but has not been previously recorded from India, 
Orsinome armata, sp. 0. 
~6.. Colear like that of O. marmorea, but legs yellower with black 
spots at the bases of the spines, upper side of abdomen blackish with 
a median posteriorly lanceolate white mark which gives off a pair of 
short branches on each side, sides of upper surface and upper portion 
of lateral surface with a chalky yellow stripe ornamental with red spots. 
Eyes very much as in O. marmorea, but the anterior medians not 
larger than posterior medians and about two diameters from the 
laterals, Mandibles with external prominence above the base of the 
fang ; fang-groove armed above in front with 3 teeth and below (behind) 
with 4, fang shorter than in O. marmorea, bent nearly at right-angles
