442 REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 
with black; all are of a pearly-white colour except the middle anteriors, which are 
dusky; the middle anteriors and posteriors are very near to each other, the distance 
between them being about equal to that between the two former. 
Legs not very long, moderately stout, rather lighter-coloured than the cephalothorax ; 
they are sparingly furnished with hairs; but the armature of the legs had suffered by the 
spider having been gummed on card, though it did not appear to present any remarkable 
difference from the ordinary types of the genus. Relative length 1, 4, 3, 2. 
Palpi moderately long, slender, not more than half the thickness of the femora of the 
first pair of legs; humeral joints slightly sinuous, curved towards the falces, and furnished 
on the outer sides with several fine bristly hairs along the entire length; cubital joint 
short, very little larger at the extremity than near the humeral joint ; it is a little curved 
and very slightly gibbous on the upperside near the extremity. The radial joint is very 
short, not nearly so long as the cubital, but dilated on each side, the outer dilatation much 
the largest and longest, and ending in a bluntish point; both dilatations are furnished 
with long hairs, especially at the extremities, and in a row round their outer margins. 
Digital joint very large; the palpal bulb (5. e. the digital joint and palpal organs together) 
forms a large, broad, stout, oval mass, its length equal to that of the humeral joint, or 
more than double that of the cubital and radial together; the great size of this joint, 
combined with the comparative weakness of the rest of the palpus, is very striking and 
characteristic. The palpal organs are highly developed, prominent, and complicated, 
showing several spines and corneous processes difficult to be described, the most tangible 
apparently being a long, slender, filiform, black spine, issuing from beneath the digital 
joint about the middle of the outer side, embracing and curving over the palpal organs 
toward their extremity, and another similar spine issuing from nearer the extremity of 
the digital joint, and curving over the palpal organs in a parallel direction to the other 
spine. The colour of the palpi is the same as that of the cephalothorax ; that of the 
palpal organs is mixed with rich red brown. 
Falces moderately strong, double as long as the height of the clypeus, straight, outer 
margin very slightly hollow, impressed in front towards the extremities, as if pinched in, 
slightly toothed at the extremities, which are nearly square; but this part was partially 
obscured by the gum with which the spider had been fixed on card. Their colour is 
rather deeper than that of the cephalothorax. 
Maaille strong, long, curved, and slightly leaning towards the labium, which is broad, 
short, and roundish-pointed at the apex. 
Sternum broad, heart-shaped, and, with the maxillæ and labium, similar incolour to the 
cephalothorax. 
Abdomen strongly convex above, and equal in length to the cephalothorax, over which 
it projects considerably; it is broader behind than in front, very sparingly furnished 
with dark hairs; colour dull blackish, freckled with numerous pale spots, especially on 
the sides, where they form lines converging towards the middle of the upperside; on 
each side of the median line forward are three largish impressed dots of a brighter 
yellow; these dots and spots (sufficiently apparent in spirit of wine) would probably be
