EPEIRA. 
361 
anterior extremity of the upper part of its abdomen is proportionally minute; its legs are 
long, the usual colour of the femora is black, and the tibiae of the second pair are curved 
and dilated. The palpi are short, and of a brownish-yellow colour; the digital joint is oval, 
convex and hairy externally, concave within, comprising the palpal organs, which are highly 
developed, complicated in structure, and of a dark, reddish-brown hue. The colours, and the 
design formed by them, are similar in both sexes. 
An adult female Epeira angulata, and an immature male which had to undergo its 
final ecdysis, were taken in 1856, near Blandford, in Dorsetshire, by the Rev. O. P. 
Cambridge. 
The descriptions of Epeira angulata given by arachnologists are, in general, so brief and 
imperfect as to render any attempt to reconcile the perplexed synonyma of this species 
almost hopeless.

The abdomen is short, broad, somewhat oviform, with a bold, conical protuberance on 
each side of the anterior extremity of the upper part, and projects over the base of the 
cephalo-thorax ; a large, reddish-brown, leaf-like mark on the upper part, which tapers to the 
spinners, and has dark, sinuous margins, comprises a green spot, situated between the tubercles ; 
the anterior part, exterior to the extremity of the leaf-like mark, and the sides have a dull- 
green tint, mottled with yellowish-green, and a broad, brownish-black band, bordered by 
greenish-yellow, extends along the middle of the under part; the sexual organs are very 
prominent, and have in connexion with them a small, pale, oval process, directed backwards; 
and the colour of the branchial opercula is yellowish-brown. The cephalo-thorax is convex, 
compressed before, rounded on the sides, and has an indentation in the medial line; it is of a 
dark-brown colour, and is clothed with pale, yellowish-brown hairs, which are densest in the 
cephalic region. The four intermediate eyes are seated on a protuberance, and nearly form a 
square, the two posterior ones being much the largest of the eight; those of each lateral pair, 
which are the smallest, are placed obliquely on a tubercle, and are almost in contact. The 
falces are strong, conical, and armed with teeth on the inner surface; the maxillae are short, 
powerful, and greatly enlarged at the extremity; the lip is triangular and pointed at the
