738 REV. 0. P. CAMBRIDGE ON NEW ARANEIDEA. _[ Nov. 1, 
Mazille rather strong, greatly bent (in an almost angular form) 
over the labium. 
Labium of a somewhat triangular form, broader in the middle than 
at its base, and pointed at the apex. 
CHORIZOOPES FRONTALIS, n. sp. (Plate XLIV. fig. 6.) 
Female adult, length 13 line. 
The general form and structure of this Spider have been sufficiently 
described above. The caput has the occipital portion prominent on 
either side, and a depression where it joins the thoracic part; the 
normal furrows and indentations are obliterated owing to the abnor- 
mal development of the caput, which usurps almost the whole cepha- 
lothorax. 
The cephalothorax is sparingly clothed with pale grisly hairs of a 
more or less dark yellow-brown colour; the region of the occipital 
prominences being palest. 
The eyes do not differ greatly in size: the upper ones of the central 
quadrangular group are the largest, and those of the lateral pairs the 
smallest of the eight ; the eyes of each of these latter pairs are nearly 
contiguous, and of a pearly white colour; the others are darker. 
The legs are of a pale yellow, banded with yellow-brown, and are 
furnished sparingly with short hairs. 
Palpi small, short, furnished with short hairs and a very fine, 
black terminal claw. 
Falces large and strong, rather prominent in front and on the 
sides, and curved when looked at from before; towards the inner 
extremity of each is a prominence with a curved margin armed with 
a sort of comb of close-set longish teeth; the colour of the mazille 
is a pale yellowish brown; that of the labcwm and sternum being 
darker. 
The abdomen is sparingly clothed with very short hairs ; it is of 
a short-oval form and very convex above, bluff and abrupt behind, 
where it has four, small, bluntish or subconical eminences, arranged 
in a transverse diamond shape, spanning the whole width of the ab- 
domen ; it does net project over the base of the cephalothorax ; and 
its colour is a dull yellowish with a brown tinge, marked with deep 
black-brown and white, forming a regular pattern, difficult to describe 
and best seen in the figure; two small white spots (followed by 
several more minute ones) are rather conspicuous on the upperside ; 
between the spinners and each of the lateral eminences, and not far 
from the former, is a large, conspicuous, round, black blotch. The 
epigyne and the orifices of the spiracles are of a deep red-brown 
colour; the spinners are short, six in number, and not very strong 
nor conspicuous. 
Adult females of this Spider were contained in collections of 
Spiders from Ceylon, in 1869, both from Mr. Nietner and Mr. 
Thwaites. I have included it in the family Epeirides, with Spiders 
of which it is evidently connected, though in the form of the max- 
illee and labium it bears strong affinity to the Theridides ; in what- 
ever family, however, it may finally be placed, there seems to be no
