1875.] NEW SPECIES OF ERIGONE. 193 
The eyes are on black spots disposed in the usual four pairs, and 
forming an area rather broader than long; they are of moderate size 
and, relatively, do not differ to any very great extent; those of the 
hinder pair are separated from each other by rather less than two 
diameters ; those of each lateral pair are contiguous to each other and 
are seated on a slight tubercle, the hind lateral eye being ratker more 
than a diameter’s distance from the eye nearest to it of the hinder 
pair; the fore laterals are the largest of the eight, and each is rather 
more than a diameter’s distance from the eye nearest to it of the fore- 
most pair; the eyes of this last pair are smallest of the eight, dark- 
coloured, but not quite contiguous to each other; the rest are pearly 
white. 
The Jegs are moderate in length and strength ; their relative length 
appeared to be 4, 1, 2, 3; there is, however, but little difference be- 
tween those of the first and fourth pairs; they are furnished with 
hairs and a few erect and slender bristles on their uppersides. 
The palpi are short but tolerably strong: the cubital joint is short, 
bent downwards, and slightly clavate at its fore extremity; the radial 
joint is short but is produced (on its whole width) at the upper ex- 
tremity into a large and widening apophysis, which curves round in 
an inward direction and has its fore half bifid, the two limbs pointing 
outward ; the inner limb is the slenderest, dark-coloured, blunt-pointed, 
curved, and somewhat cylindrical in form; the outer limb is stronger 
than the other, and goes off at its extremity into a fine and slightly 
curved point ; this apophysis covers the greater part of the digital 
joint, which is small but of ordinary oval form: the palpal organs are 
prominent but not very complex; from their extremity, rather on the 
outer side, issues a long, dark brown, filiform, sharp-pointed spine, 
which bends round sharply upwards and backwards, continuing in 
that direction in a large but somewhat irregular coil, the point being 
directed inwards, near the extremity of the palpal organs and not far 
from the origin of the spine; another short, black, filiform spine runs 
close over the base of the palpal organs in a transverse direction, but 
it was difficult to see either its point of origin or its termination. 
The falces are moderate in length and strength, rather directed 
backwards and armed with teeth towards their extremities on the 
inner side. 
The mazille, labium, and sternum are normal in form, the last 
being slightly suffused with dusky brown. 
The abdomen is short, oval, very convex above, and projects strongly 
over the base of the cephalothorax ; it is jet-black in colour, glossy, 
and clothed very sparingly with short hairs. 
An adult male of this very distinct species was received from M. 
Simon, by whom it was found in Corsica. 
ERIGONE TRUNCATIFRONS, sp. n. (Plate XXVII. fig. 4.) 
Adult male, length ? line. 
The whole of the fore part of this Spider is of a bright yellow colour, 
the upper part of the cephalothorax, as well as the femora and tibize 
of the legs, being tinged with orange. The caput is broad, a little
