DESCRIPTION OF A NEW ARANEIAD RAINBOW. 
83 
the two comprising the second row are separated from their 
anterior neighbours by a space equal to rather less than twice 
their diameter, and from each other by about three diameters ; 
the remaining two lateral eyes are located in the angles of the 
cephalic segment at a distance from the tubercular eminence of 
about 0*5 mm. 
Legs long, robust, armed with strong spines, yellow-brown with 
dark annulations, clothed on the outer margins with hoary grey 
hairs, on the inner margins with ferruginous grey ; coxae densely 
clothed underneath with grey hairs. Relative lengths 1 = 2, 4, 3. 
Palpi long, similar in colour, armature, and clothing to legs. 
Falces long, robust, arched, glossy, sparingly clothed with black 
hairs, apices divergent, yellow at base to about one-third their 
length, where it terminates suddenly, and is thence dark brown 
to tips ; the upper margin of the furrow of each falx is armed 
with a row of four teeth, of which the two nearest the base are 
the longest and strongest ; the lower margin is armed with two. 
Maxilla: broad, arched, moderately long, divergent ; laterally 
they are yellowish -brown, and clothed with rather long, hoary 
greyish hairs ; inner surfaces glossy, pale llesh-coloured and naked, 
but the edges are furnished with dense hoary scopuke. 
Labium broader than long, arched, obtuse at apex, yellow-brown 
from base to about one-half its length, thence pale llesh-coloured. 
Sternum shield-shaped, moderately arched, densely clothed with 
short greyish hairs. 
Abdomen large, ovate, boldly projecting over base of cephalo- 
thorax, grey, with dark brown markings, and a large brown patch 
at the centre; sides grey ; at the highest point of the anterior 
extremity there is a recurved row of nine tubercles, the central 
one of which is by far the largest and most prominent ; besides 
these there are on each side of the superior surface of the abdomen 
twelve tubercles, the first nine of which are distributed over three 
slightly procurved rows of three each; the fourth row on each 
side consists of two each, and the twelvth tubercle is solitary; the 
total number of tubercles is 33 ; the median portion of the superior 
surface is, with the exception of two rather deep circular depres- 
sions, smooth; inferior surface yellow-brown with dark markings 
and moderately clothed with hoary hairs laterally, and yellowish 
pubescence in the median line. 
Epigyne , a small tri-lobed tubercular eminence, arched in front, 
hollow within.
