242 ARANEIDEA. 
slightly shorter than its anterior side. The height of the clypeus is nearly equal to half that of the facial 
space, or at any rate more than one-third of it. 
Legs long, rather slender, 2, 1, 4,3; 2 and 1 nearly equal in length ; 3 and 4 much shortest ; spines strong, 
and on all the joints excepting the tarsi and metatarsi; colour yellow, with a broad yellowish-brown 
annulus at the anterior extremity of the tibiz, and another of less extent and distinctness at the anterior 
extremity of the tarsi and metatarsi. 
Palpi short, similar in colour to the legs. Cubital and radial joints short; the latter is the shorter and has a 
strongish apophysis at its extremity on the outer side, as long or longer than the joint, somewhat 
widened and flattened and emarginate at its extremity, the upperside of which is prolonged into a 
somewhat nail-like, slightly curved, blunt-pointed, corneous termination ; the digital joint is of moderate 
size and broadish-oval form. The palpal organs are simple, consisting of a rather flattened-spherical 
corneous lobe, round the outer margin of which runs a long, slender, tapering black spine, issuing from its 
inner side; the extremity of this spine forms a circular coil on the outside of the joint, in front of and 
below the point of the radial apophysis. 
Falces rather small, subconical, and of a yellowish colour. 
Mazille, labium, and sternum yellow. 
Abdomen oval, rounded before, obtusely pointed behind, pale yellowish, covered on the upperside with 
almost confluent whitish cretaceous-looking spots, leaving a pale longitudinal central tapering stripe on 
the fore half. Spines on the abdomen black, long, strong, and very prominent.

Pedo plumosus, sp. n. 
Adult female, length very nearly 4 lines. 
The general hairy covering of this spider, at any rate mostly on the abdomen and uppersides of the legs, 
consists of plumose hairs, rather long, but lying flatly on the surface, and the pattern on the abdomen 
appears to be chiefly, if not entirely, due to the colours of these hairs. On close examination of 
P. ornatus (antead, p. 220, t. 26. fig. 14), the type of the genus, I find that the hairs are similarly formed 
in that species. This character was overlooked in the description (J. ¢.). 
The cephalothorax is of a deep rich reddish-brown, sprinkled with fine grey plumose pubescence. 
The eyes are, in their general position, like those of P. ornatus; the interval between the hind-centrals is 
distinctly greater than that between each and the hind-lateral eye next to it. 
The legs have the normal generic armature. The first and second pairs have their femora, and the two 
posterior pairs have their femora, tibie, and genuz, very nearly similar in colour to the cephalothorax ; 
the rest of the first two pairs is light brownish-yellow, that of the two hinder pairs is of a darker brown, 
and all are more or less clothed thinly with light grey plumose hairs or pubescence. 
The falces are similar in colour to the cephalothorax, strong, prominent towards their base in front, and 
furnished with strong prominent bristles. 
The palpi are dark yellow-brown, the terminal claw very fine. 
The maaille are normal in form; their inner sides and extremities are furnished with a dense fringe of strong, 
dark grey, plumose hairs. The colour of the maxillx is like that of the cephalothorax, with a broad, 
well-defined white inner margin. 
The labium is similar in colour to the maxille, the apex white. 
The sternum is similar to the cephalothorax in colour, and sprinkled with grey plumose pubescence. 
The abdomen is of a short, broadish-oval form; of a dark slightly chocolate-brown hue on the sides ; underside 
and hinder extremity covered thinly with grey plumose hairs. Along the middle of the upperside, from 
the fore-end to a little way above the spinners, is a broad, central, longitudinal, foxy-red band, sprinkled 
with white hairs, and occupying the greater part of the upperside; this band is broadest near the middle, 
where it has a slightly dentate margin on each side, and the plumose hairs on it are some of them grey, 
On the hinder part just above the spinners is a large, somewhat quadrate figure, formed by a distinct 
marginal border of white hairs ; the lower extremity of the figure, however, is not defined, and there is
