Cambridge. — On a new Slides of Trapdoor Spicier. 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 lejfs are strong, rather short, of a brownish-yellow colour, and 

 furnished with hairs, bristles, and spines. The latter axe most numerous, 

 though shortest and most robust, on the metatarsi and tarsi of the third 

 and fourth pah's — those on the third pair being on the upper and lower 

 sides, while they are underneath only on the fourth pah' ; the spines on the 

 first and second pairs are beneath the tibias and metatarsi, and are longer 

 and less strong than those of the two hinder pairs. The genual joints of 

 the thhd 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 tibise also of the third i3air have a single 

 short strong spine on the outer sides. In one specimen, however, (that of 

 which the genual joint had eight spines) the tibiae had two, in another with 

 seven on the genua, the tibise had three ; and in another there were three on 

 the genua with two on the tibiae. 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 pahs are furnished beneath with a broad and compact scopula. 

 The relative length of the legs "is 4, 1, 2, 3. TlliQ palpi are short and strong, 

 similar in colour 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 scopula beneath its whole length, and terminates with a single 

 strong curved denticulate claw. 



The falces are strong and prominent, of a dark reddish yehow-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.
