respecb. They are in two curved rows, forming a transvei'se oval figure, about 

 double as long as it is broad at its broadest diameter. The eyes of the hinder 

 row are equi-distant from each other. The fore central eyes are I'ather nearer 

 together than each is to the lateral of the same row on its side. Those of each 

 lateral pair are seated slightly obliquely on a not very prominent tubercle, and 

 are near to each other, but not contiguous. 



The Legs are long and tolerably strong ; their relative length is 1, 2, 4, 3, 

 and they are furnished with spines (not very long nor strong), and with 

 numerous — some nearly erect — hairs of different lengths. The colour of those 

 of the two foremost pairs is yellow-brown, the femora and genuse being darker 

 than the rest, and with a very faint indication of a paler annulatiou both on 

 the femora and tibise. The two hinder pairs are similarly coloui-ed, but have 

 two distinctly marked yellow annulations on each of the femoral and tibial 

 joints ; each tarsus terminates with three curved claws ; the superior ones 

 pectinated beneath the hinder half; the inferior one much the smallest, and 

 strongly bent downwards near its base, where it has one or two teeth. 



The Palpi are rather long and slender ; they are of a reddish-yellow brown 

 colour, the basal part of the radial joint being pale yellow brown, shading off 

 into the redder part. The humeral joint is bent inwards ; the radial is more 

 than double the length of the cubital joint, and rather strongest at its fore 

 extremity, near the outer side of which are two small apophyses ; that nearest 

 the base of the digital joint is the largest, of a flattened form and truncate 

 extremity, the other (behind it) is sharp pointed, and of a somewhat tooth-like 

 form. There is also a small prominent point beneath the larger apophysis 

 above-mentioned. The digital joint is small, oval, but its extremity is greatly 

 produced in a long cylindrical form, being a greatly exaggerated example of a 

 somewhat similar form in Argyroneta and Tegenaria. The length of the 

 digital joint considerably exceeds that of the radial and cubital together, being 

 about equal to that of the humeral joint. The palpi, like the legs, are furnished 

 with a few slender spines and long hairs ; of the former are several longish 

 conspicuous ones on the digital joints. The palpal organs are contained within 

 the oval basal part of the digital joints ; they consist of a simple whitish oval 

 lobe, with a red-brown corneous lateral margin, probably an independent, 

 though closely adhering, spine, but this I could not ascertain satisfactorily ; 

 there are also a sharp-pointed dark red-brown spine on their inner side, and a 

 stronger obtuse corneous projection near their extremity, and a small one on 

 the outer side. 



The Falces are long, strong, divergent, and projecting forwaixls ; their 

 length is very nearly equal to that of the cephalo-thorax ; the fangs are long 

 and strong, and beneath them are several strong sharp teeth aloiag the inner 

 side of the falces, which are of a deep rich reddish chestnut brown colour, and
