150 ARANEIDEA. 
extremity emitting an excessively long, slightly tapering, nearly straight process, which ends in a sharp 
spine-like point; there are also some long, strong spines and processes directed from the outer side 
backwards; the outermost of these is perhaps the most conspicuous, being a strong tapering dark- 
coloured spine of great length and a somewhat corkscrew form. 
Falces rather long, not very powerful, pale yellow in colour; a little prominent at the base in front, with a 
kind of lateral pushing in or excavation at that part, near which there is also a strong black spine-like 
bristle ; below this, about halfway towards the extremity, is another strong prominence furnished at its 
fore side with a group of very short, blunt, dentiform spines, and below this again is a single strong bent 
tooth directed forwards, with again another on the inner side close to the fang. 
Mawille, labium, and sternum similar to the legs in colour. The maxille meet over the labium, which is much 
' broader than high, and the sternum is nearly round, having a very slight angularity at the hinder 
extremity. 
The abdomen is oval, broader behind than before, rather produced and obtuse at its upper hinder extremity, 
and of a pale dull luteous yellow hue. Spinners'very short and compact.

«Found under a leaf close to a small irregular thickish web.” 
METAGONTA, Simon. 
Metagonia caudata, sp. n. 
Adult female, length 13 lines. 
Cephalothorax round behind, drawn out in front into a very prominent clypeus, whose extremity, looked at 
from above and behind, is of a somewhat roundish-pointed form, and nearly equal in length to that of the 
rest of the caput. Caput small, the normal indentation dividing it from the thorax strong; thoracic 
indentation very large and deep. The colour of the whole of the fore part of the spider is yellow. 
The eyes, six in number, are in two groups in a transverse line; each group, with three eyes, contiguous to 
each other, and forming thus a triangle, or they may perhaps be conveniently described as having two 
eyes contiguous to each other in a line at right angles to the transverse axis of the caput; on each side 
of the caput, and within the two lines thus formed, are two others, one contiguous to each two and placed 
in the middle of the line formed by each two; the inner eye of each triad is of an oval form, and the 
two inner eyes are separated by an interval a little greater than their longest diameter. Hach group of 
eyes is seated on a prominence. 
The legs are of great length, 1, 2, 4, 3, and very slender, furnished inconspicuously with fine hairs; their 
colour is yellow, the genua deep brown, with the extremities of the tibie and the posterior extremity of 
the metatarsi deep brown or black. 
The falces are short, subconical, moderately strong. 
The maxille are long, inclined over the labium, which is large, broader than high, its apex narrower than the 
base, and a little roundly truncated. 
The sternum is large, of a somewhat subtriangular form, drawn out and truncated at its posterior extremity, 
of a dull blackish-brown hue, speckled and laterally margined with yellow. 
The abdomen is rather elongate, and has its hinder extremity drawn out into a caudiform obtusely-pointed 
elongation, which is, however, less in length than the rest of the abdomen, being about as long as the 
distance from the spinners to the genital aperture. The abdomen is dull luteous yellow in colour, 
clothed thinly with very fine hairs. The genital aperture is simple and inconspicuous, but of charac- 
teristic form.
