440 REV. 0. P. CAMBRIDGE ON NEW ARANEIDEA. [May 16, 
ocular area). The occiput, which is paler than the rest, is clothed 
with greyish hairs, of which some in the centre are quite white ; 
there is also a patch of white hairs bebind each of the large fore 
central eyes, a smaller one almost in a line between the posterior pair 
of eyes, with a few similar hairs round these last. The thorax has a 
narrow lateral submarginal band (on each side) of white hairs; anda 
dense row of similar hairs projects prominently forwards just above 
the lower margin of the clypeus. 
The legs are yellow-brown, those of the first pair, excepting the 
rsi and metatarsi, much the darkest; the others are obscurely 
annulated with dark yellow-brown. The spines (on the first two 
pairs) are 4 (in two pairs) beneath the metatarsi (these are the 
strongest), and 6 (in three pairs) beneath the tibiz. On the third 
and fourth pairs of legs the spines are more numerous, but less 
strong and more irregularly placed. 
The palpi are moderately long; the cubital joint is of a clavate form, 
double the length of the radial, and has some whitish hairs on its 
anterior surface. The radial joint has a strong, but short, obtuse 
prominence behind, and a curved, shining, tapering, sharp-pointed 
apophysis on its outer side. The digital joint is of moderate size 
(but longer than the cubital), and of an oval form; the palpal organs 
are simple, not very prominent, and (apparently) closely surrounded 
with a strong black spine. 
The falces, mavzille, labium, and sternum are yellow-brown ; the 
falces are the darkest, and have, at their extremities on the inner side, 
two short parallel rows of small but distinct denticulations, within 
which the fang lies when at rest. 
The abdomen is dark brownish black, varying to deep brown in 
parts ; on the upperside two large, somewhat crescent-shaped paler 
markings occupy each side of the anterior portion, and are clothed 
with shining white hairs ; these are obliquely crossed at their hinder 
ends by a similarly clothed pale stripe, thus giving the appearance 
of atolerably perfect large white circle occupying the whole fore 
half of the upperside of the abdomen; the posterior half is marked 
with several ordinary pale angular bars or chevrons, thickly clothed 
with whitish hairs. The sides and underside are pale dull yellowish 
brown, the former obscurely and obliquely marked with dark 
brown. The spinners are small, but of tolerable and equal length and 
prominent. 
A single example, but in very perfect condition, was received in 
Mr. Traill’s Amazon collection.
