1875.] NEW SPECIES OF ERIGONE. 401 
is large, and has its hinder extremity produced into a curved horn- 
like projection, its point being red-brown, apparently of a corneous 
nature, and directed outwards. The palpal organs are highly deve- 
loped, prominent, and complex ; two bright red-brown strong corne- 
ous processes are most noticeable, one of them curved or folded in a 
circular form at their base on the outer side; the other, longer and 
stronger, issues from their inner extremity, and, running backwards, 
curves round their base. 
The falces are moderate in length and strength ; they are directed 
backwards towards the labium, and are armed with a few minute 
teeth on their inner edge near the extremity. 
The mazville, labium, and sternum are of normal form. 
The abdomen is oval, tolerably convex above, and projects fairly 
over the base of the cephalothorax ; it is of a greenish black colour, 
mottled and lined with pale yellowish (when seen through spirits of 
wine) and thinly clothed with hairs. 
The female resembles the male in colours and general characters ; 
and the genital aperture is rather complex in its form. 
This species is very nearly allied to the European form, H. cont- 
gera (Cambr.), but may, among other characters, be easily distin- 
guished by the less strong and more curved process at the base of the 
digital joint, as well as by a quite different structure of the palpal 
organs. 
Examples of this Spider were received from Mr. Emerton, by 
whom they were found under leaves at Swampscott, near Boston, 
U.S. A., in March 1874. 
ERIGONE CORNUPALPIS, sp.n. (Plate XLVI. fig. 8.) 
Adult male, length 17 line. 
The cephalothorax, falces, and maxille of this Spider are of a 
yellow-brown colour ; the legs and palpi dull orange-yellow, tinged 
slightly with brown; the labium and sternum dark yellow-brown ; 
and the abdomen dull blackish, tinged with olive-green, 
The form of the cephalothoraz is of the ordinary type; a very 
slight dip or hollow is observable in the profile-line just behind the 
occiput ; and the normal grooves and indentations are distinct, but 
not strongly marked ; the height of the clypeus, which slightly pro- 
jects, is equal to half that of the facial space. 
The eyes are rather large, on black spots, and closely grouped 
together in the usual position; those of the hinder row are separated 
by as nearly as possible equal intervals of half a hind central eye’s 
diameter ; those of each lateral pair are placed obliquely on a tubercle, 
the foremost of these pairs are the largest of the eight, and each is 
separated from the fore central eye on its side by an interval not 
much exceeding half the diameter of the latter ; those of the fore 
central pair are smallest of the eight, very near, but not quite con- 
tiguous to each other, 
The falces are strong and of tolerable length ; they are very nearly 
vertical ; and each appeared to have, on the outer side of its front 
surface, a longitudinal row of minute fine tooth-like spines ; there are
