1875.) NEW SPECIES OF ERIGONE. 199 
are composed is one at their base on the outer side, rather prominent 
and obtuse at its end; from near their extremity, on the same side, 
a strongish pale spine curves downwards and backwards, ending in a 
slender, curved, filiform point ; and in front of this is another, shorter 
and stronger, and tapering to a point, but without a filiform ending. 
The falces are moderately long and strong, and are straight, but 
inclined backwards towards the labium. 
The abdomen is oval, moderately convex above, and projects a 
little over the base of the cephalothorax; it is glossy, black, and 
sparingly clothed with short hairs. 
A single adult male of this very distinct Hrigone was received from 
M. Simon, by whom it was found in France (Col de Natoia, between 
Embrun and Barcelonnette). It is allied to Hrigone (Walckenaéra) 
humilis (Blackw.), E. affinitata, Cambr., and E. crassiceps (Westr.) 
=E. bucula (L. Koch). The last two species may be distinguished 
from £. vaporariorum by their more elevated caput; while EL. humilis 
has a broader and more obtuse termination to the caput, and is without 
the transverse depression between the ocular area and the occiput, 
and the backward-directed hairs from this area, both of which are 
strongly characteristic of the present species. 
ERIGONE CORNICULANS, sp.n. (Plate XXVII. fig. 9.) 
Adult male, length 13 line, rather more than 23 millimetres. 
The cephalothorax ot this species, which is very nearly allied to 
E. monoceros (Wid.), is yellow, the caput, as well as the normal 
indentations, being slightly suffused with dusky brown; the fore 
part of the caput is slightly but gradually elevated, and a little pro- 
minent ; and from the centre of the ocular area there rises a distinct 
horn-like emiuence ; this eminence is slightly curved, projects for- 
wards, and is of a tapering form, blunt at the extremity, or of a 
somewhat subconical shape; its fore side and summit are furnished 
with some short, curved, clavate, prominent hairs, and some ordinary 
ones issue from its hinder part. 
The eyes are of tolerable size, and seated in four pairs round the 
eminence on the fore part of the caput, those of each pair respectively 
being contiguous to each other. The four pairs describe very nearly 
a circle; but the interval,between each lateral pair and the hinder 
pair is greater than that between the lateral and front pairs; the 
former interval is equal to the diameter of one of the hinder pair of 
eyes, the latter interval to the diameter of one of the front pair. 
The /egs are long and slender, their relative length being 4, 1, 2, 3; 
there appeared to be, however, but little difference between those 
of the first and second pairs; they are similar in colour to the 
cephalothorax, and are furnished with inconspicuous hairs and fine. 
bristles. 
The palpi are slender and of moderate length ; their colour is pale 
yellow; the digital joint, however, is suffused with brown, and the. 
radial joint is margined with black-brown on its inside: the cubital 
joint is clavate, or enlarges gradually from its hinder to its fore ex- 
tremity : the radial joint is shorter, but stronger, than the cubital, and.
