REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 443 
indistinct in the living specimen; the plates of the spiracles are large, and of the same 
colour as the legs. 
An adult male of this spider (which is allied to JV. livida, Bl., but easily distinguished 
by the unusually large proportions of the palpal bulb) was forwarded to me in 1864 by 
my lamented friend the late Rev. Hamlet Clark, by whom it was captured near Dover, 
and after whom I have specifically named it. An adult example of the same species 
has also been (in 1866) sent me by Mr. Morris Young, who captured it near Paisley, 
Scotland. | 
NERIENE NEGLECTA, n.sp. (Pl. 56. no. 31, a, b, c, d, e.) 
Male adult, length +; of an inch. 
Cephalothorax flattish, scarcely compressed on the sides forwards; caput very slightly 
sloping from the occiput to the eyes; normal furrows and hind indentation well defined ; 
very smooth and glossy ; indentation defining the caput strong on either side below the 
occiput; clypeus nearly vertical, and visibly less in height than the length of the space 
oceupied by the four central eyes ; colour yellow-brown ; a few bristly hairs in the median 
line, directed forwards. 
Eyes eight, in two rows slightly curved from each other, forming a regular oval patch 
on the fore part of the caput; all are seated on slightly tuberculate black spots, and are 
nearly equal in size; the middle anteriors are slightly the smallest; and the middle pos- 
teriors are a little further from each other than each is from the end one on its side ; the 
middle anteriors are nearer together than each is to its end one, but are not contiguous; 
those of each lateral pair are contiguous and rather obliquely placed, thus making the 
front row shorter than the hinder one; the distance between one of the middle posterior, 
and its opposite anterior is no more than a diameter of the former; all are pearly white, 
except the middle anteriors, which are dark. 
Legs moderately long, tolerably strong, fairly furnished with longish fine hairs; colour 
pale yellowish ; relative length 1, 4, 3, 2. 
Palpi moderate in length and strength; of the same colour as the legs, except the 
radial and digital joints, which are rather darker ; humeral joint curved towards the falces ; 
the cubital and radial joints do not differ much in length ; both are clavate and strongly 
bent forward; the radialis more clavate than the cubital, and has the outer side con- 
siderably, broadly, and obtusely produced, and furnished with a few long bristly hairs, 
which extend to the extremity of the palpal organs; the inner side is also slightly pro- 
duced, and furnished with shorter hairs; the digital is strongly convex near the base, 
rather pointed-oval in form, and hairy. 
Palpal organs well developed, not very complicated, consisting of several corneous and 
spiny processes, of which one projects perpendicularly from near their middle, and is 
nearly straight, acute, and of a pale diaphanous appearance, and another, more obtuse and 
cylindrical, projects horizontally from the extremity; the convex sides of the digitals 
are turned toward each other. 
Falces long, strong, straight, perpendicular, rather gibbous near the base, compressed
