indentation in the medial line; it is of a brownish-black colour, 
with three longitudinal yellowish-white bands, one in the middle, 
another on each side, and with lateral margins of the same hue. 
The eyes are small, nearly equal in size, and disposed on the 
anterior part of the cephalothorax in two transverse curved rows, 
whose convexity is directed forwards; the anterior row, which is 
the less curved, is situated near the frontal margin, and the in- 
termediate eyes, which are seated on a tubercle, are the largest, 
and the lateral ones rather the smaliest of the eight; the lateral 
eyes of both rows are widely apart, and are placed on minute 
tubercles, and the intermediate ones form a trapezoid whose an- 
terior side is the shortest. The falces are short, conical, vertical, 
and of a yellowish-brown colour. The maxille are straight, 
powerful, and greatly enlarged and rounded at the extremity, 
which is rather prominent on the inner surface; and the lip is 
short and triangular. These organs are of a reddish-brown 
colour. The sternum is of an oblong-oval form; it is thinly 
clothed with white hairs, and has a brownish-black hue. The 
abdomen is of an oblong-oviform figure, somewhat convex above, 
and projects over the base of the cephalothorax ; the upper part 
is of a yellowish-white colour, finely reticulated with brown; a 
narrow dark-brown band extends along the middle, which is 
broadest towards its anterior extremity, and is crossed by several 
very short lines of the same hue near the spinners, and from 
these organs two short, dark-brown, lateral streaks are directed 
forwards; the sides are minutely spotted with brown, and a 
broad brownish-black band, bordered by dull white, extends 
along the middle of the under part; the spinners are eight in 
number, those of the inferior pair, which are the shortest, con- 
sist of a single joint each, and are united throughout their entire 
length. 
That the Velede evidently possess many well-marked charac- 
ters in common with the spiders of the genus Uloborus is asserted 
in the ‘ History of the Spiders of Great Britain and Ireland,’ 
part 1. p.151; but as MM. Dufour, Hahn, and Koch affirm 
that the snare of Uloborus Walckenaerius is constructed on the 
same plan as those of the Hpetride, it may be inferred that it 
has not the additional pair of spinners and calamistra, as the 
snares of all spiders provided with this apparatus, whose economy 
is known, exhibit unmistakeable evidence of its having been 
employed in their fabrication.
