CamBripce.—On a new Species of Trapdoor Spider. 285 
with coarse adpressed dull sandy-grey pubescence, the ocular area being 
almost all black. The eyes are eight in number, seated on a slight oval 
eminence close to the fore extremity of the caput, and forming a transverse 
rectangular figure, whose longitudinal is rather less than half its transverse 
diameter. They are rather unequal in size. The four largest form the 
four corners of the quadrangle, those at its anterior corners being the 
larger; the two next in size are seated in a transverse line in the centre of 
the quadrangle; and close to the inner side of each posterior eye, but not 
quite contiguous to it, is another of a yellowish-white colour and flattened 
form, contrasting strongly with the dark hue of the rest. 
The legs are strong, rather short, of a brownish-yellow colour, and 
furnished with hairs, bristles, and spines. The latter are most numerous, 
though shortest and most robust, on the metatarsi and tarsi of the third 
and fourth pairs—those on the third pair being on the upper and lower 
sides, while they are underneath only on the fourth pair; the spines on the 
first and second pairs are beneath the tibie and metatarsi, and are longer 
and less strong than those of the two hinder pairs. The genual joints of 
the third pair are furnished with short strong spines, but the number does 
not appear to be constant—varying from three to (in one example) eight, 
and sometimes differing, by one or so, on the opposite sides of the same 
spider; no example, however, out of twelve adults examined, is entirely 
without spines on this joint; the tibie also of the third pair have a single 
short strong spine on the outer sides. In one specimen, however, (that of 
which the genual joint had eight spines) the tibie had two, in another with 
seven on the genua, the tibiæ had three; and in another there were three on 
the genua with two on the tibie. The tarsi terminate with three strong, 
curved claws, those of the superior pair are the strongest, and are furnished, 
so far as I could ascertain, with three teeth on the under side of the hinder 
portion, near the middle; the central tooth being much longer and stronger 
than the one above and below it, but the denticulation of these claws seems 
to vary a little on the different legs. The tarsi and metatarsi of the first 
and second pairs are furnished beneath with a broad and compact seopula. 
The relative length of the legs is 4, 1, 2,8. The palpi are short and strong, 
similar in eolour to the legs, furnished with hairs and bristles, and a few 
long tapering spines beneath the radial joint; the digital joint has a broad 
compact seopula beneath its whole length, and terminates with a single 
strong curved denticulate claw. 
The falces are strong and prominent, of a dark reddish yellow-brown 
deepening almost to black at the fore extremity ; they are furnished with 
sandy-grey hairs mixed with strong dark hairs and bristles, and with a 
group of short strong spines on the upper side of their fore extremity.
