14 ARANEIDEA. 
Eyes closely grouped in four pairs at the extreme part of the caput, rather unequal in size; the hind central 
- pair the largest; they are in two curved rows whose convexities are directed away from each other, 
describing a regular, transverse oval figure. 
Legs not very long, 4, 1, 2, 3, those of 4, 1, 2 not differing much in length. They are armed with long, but 
not very strong spines. 
Falces short and rather weak, vertical. 
Mazwille short, rounded at the extremity, somewhat bent and inclined to the Jabium, which is short and very 
slightly pointed at the apex. 
Abdomen rather broadest behind, being somewhat drawn out before, and projecting greatly over the thorax. 
Mangora trilineata, sp. n. 
Adult female, length 13 to 2 lines. 
Cephalothorax brownish-yellow marked with three longitudinal deep bistre-brown lines, a central, and a sub- 
marginal lateral one on each side. The central line scarcely reaches the ocular area, and all three are 
plainly visible in all specimens, but not always equally strong. 
The legs, falees, maxille, labium, and sternum are similar in colour to the cephalothorax; in some examples 
the legs are of a rather brighter hue. 
The four central eyes form a quadrangular figure whose longitudinal diameter is greater than its transverse 
one, and its anterior side the shortest. Those of each lateral pair are seated very slightly obliquely, but 
contiguous to each other. 
The abdomen is of a yellow-brown ground-colour, with a longitudinal dentated band on the upperside, varied 
with black and deep yellow-brown ; this band is broadest on the hinder half (in some examples it is obsolete 
on the fore part), and some short lateral blackish stripes often connect the angles with an irregular 
longitudinal lateral black stripe, so that both the angles themselves, as well as the connecting and lateral 
stripes, are often scarcely visible, and sometimes obsolete ; but the ground-colour on the upperside and sides 
is spotted more or less densely with silvery spots, and this applies to all the examples I have seen. The 
underside has a few silvery spots on each side, but they are often wanting. It may thus be seen that the 
abdominal pattern is liable to much variation in respect to its completeness, but it is generally traceable, 
and characteristic enough for determination. The genital process is small, inconspicuous, and but ver; 
slightly prominent when looked at in profile.

Numerous examples. 
Mangora picta, sp. n. 
Adult female, length 14 line ; adult male, very slightly over 1 line. 
In its form, colours, and markings this spider is exceedingly like M. trilincata, and the abdominal pattern 
presents the same variations. It is, however, a smaller spider. The hind central pair of eyes are rather 
larger and nearer together. The genital process of the female is very different, being conspicuous and 
prominent. 
The male resembles the female in colours and markings, but the spines on the legs are stronger. 
The palpi are very short, the cubital joint has a long, curved, tapering, filiform, pointed spine at its fore 
extremity. The palpal bulb is globular. The palpal organs are well developed and prominent, but not 
very complex, with a black tapering spine curved in a circular form beneath their anterior extremity.
