1875.] NEW SPECIES OF ERIGONE. 203 
tremity on the underside a small, sharp, black, tooth-like spine, 
directed rather backwards; from the outer side of this joint there 
arise several strong bristles, besides others less strong: the digital 
joint is not very large, it is of a short oval form, and has a strongish 
prominence past the middle of the outer side: the palpal organs are 
prominent but not very complex ; at their extremity on the outer side 
is a very strong, tapering, sharp-pointed, strongly curved spine or, 
rather, spiny process. 
The falces are small, vertical, armed with a few very minute teeth 
on their inner sides near the extremity, and similar to the cephalo- 
thorax in colour. 
The mazille and labium are of normal form, and similar in colour 
to the falces. 
The sternum is of a deep brown colour. 
The abdomen is oval, tolerably convex above, jet black in colour, 
glossy, and sparingly clothed with hairs. 
An adult male of this very distinct species was received in 1874 
from M. E. Simon, by whom it was found in Algeria. 
ERIGONE STYLIFRONS, sp.n. (Plate XXVIII. fig. 12.) 
Adult male, length not quite 1 line. 
The whole of the fore part of this Spider is bright yellow, the 
cephalothorax being strongly tinged with reddish orange, and the 
femora and tibiz of the legs with orange: the caput is more or less 
suffused with black-brown ; towards its fore part is a not very large 
oval eminence, the hinder portion of which is obtusely pointed and 
directed backwards on each side ; dividing it from the lower segment 
of the caput is a strong longitudinal indentation, extending from 
each hind lateral eye to the hinder part of the eminence ; in front of 
this eminence is another small one, from which two sharply curved or 
bent, styliform, prominent and divergent projections issue, these pro- 
jections are of a pale yellowish colour, diaphanous, and their sharp- 
pointed extremities are directed backwards and outwards ; between 
them and the fore central pair of eyes are some short prominent 
black bristly hairs. 
The eyes are small, not greatly differing in size, and are placed in the 
usual four pairs on black spots ; those of the hinder pair are separated 
from each other by a diameter’s distance, in a transverse line near the 
upper fore margin of the eminence on the caput; those of each 
lateral pair are contiguous to each other, and placed on a slight 
tubercular eminence; those of the fore central pair are smallest of 
the eight, dark-coloured, almost contiguous, and placed a little in 
advance of the straight line formed by the two fore lateral eyes. 
The extreme length and breadth of the ocular area are about equal ; 
if any thing, the breadth is rather the greatest. 
The legs are tolerably long and slender, except the femora of the 
first and second pairs, which are stronger than usual, principally 
towards their base on the upperside ; their relative length is 1, 4, 2,3; 
and they are furnished with hairs only. 
The palpi are slender and moderately long, the cubital joint is
