1875.] NEW SPECIES OF ERIGONK. 195 
ERIGONE HABILIS, sp. n. (Plate XXVII. fig. a) 
Adult female, length 13 line. 
The cephalothoraz of this fine species is of a deep rich chestnut- 
brown colour and very glossy ; the caput is roundly convex above 
and slightly elevated ; the thoracic junction is also rather elevated, 
so that between this point and the caput there is (when looked at in 
profile) a deepish hollow; the thoracic indentations are rather strong] 
marked, and the clypeus (the height of which is about half that of 
the facial space) projects a little forwards towards its lower margin. 
he eyes are in four pairs, of tolerable size, and form a some- 
what roundish oval figure ; those of the hind central pair are sepa- 
rated by an interval equal to an eye’s diameter, and each is separated 
by an equal space from the hind lateral eye on its side; those of each 
lateral pair are slightly obliquely placed, and are contiguous to each 
other ; those of the fore central pair are the smallest of the eight, and 
situated rather beyond the straight line formed by the fore laterals, 
They are not quite contiguous to each other, but are separated by a 
small interval equal to that which divides each of them from the fore 
lateral eye nearest to it, 
The /egs are long and strong, particularly the femora and tibize 
of the first two pairs; and their relative length appeared to be 4,1, 
2, 3; their colour is yellow, except the femora, which are a bright 
rich orange-red, and the tibiae of the first and second pairs, which are 
strongly suffused with brown ; they are all well clothed with hairs, 
especially the tibize of the two pairs just mentioned. 
The palpi are short, of a dark greenish yellow-brown colour, and 
furnished with hairs and longish bristles, 
The falces are tolerably long and strong, slightly inclined backwards, 
a little prominent near their base in front, and similar in colour to 
the palpi; they are armed with sharp teeth towards the extremities 
on their inner sides. 
The mazille and labium are of normal form; and their colour is 
similar to that of the falces, that of the sternum being like that of 
the cephalothorax. 
The abdomen is oval, and prejects well over the base of the cepha- 
lothorax ; it is of a dull black colour, sparingly clothed with short 
hairs : the genital aperture is of simple but characteristic form. 
A single example of this Spider was received in 1873 from M. Eu- 
géne Simon, by whom it was found at the Col de Natoia between 
Embrun and Barcelonnette. 
Although it is posssible that this may be the female of some male 
already described, I am inclined to think it is of a new Species. It 
is allied to EF. unicornis, Cambr., and to E. clara (id.); but the 
form of the cephalothorax is different and very characteristic, as also 
is the length, size, and colour of the legs, the brown tibial joints of 
those of the first and second pairs, with their more conspicuous 
clothing of hairs, making them very conspicuous. 
It is impossible to conjecture what structure the male may possess ; 
but it will be probably found to resemble the female in general 
colouring as well as in that of the tibize above mentioned.
