CLASS ARACHNIDA. 
divided into three groups ; one on each side, formed of three 
eyes, disposed in a triangle, and the third in the middle, a 
little anterior, composed of two other eyes, and on a transverse 
line. 
Pholcus phalangista , ( Araignee domestique a longues 
patles Geoff.) pli. phalangioides , Walck., Hist, des Aran, 
fasc. 5, tab. x. Body long and narrow, of a very pale, or 
livid yellow, pubescent ; abdomen almost cylindrical, very 
soft, and marked above with blackish spots ; feet very long, 
very fine, with a whitish ring at the extremity of the thighs 
and legs. 
Common in houses, where it spins, at the angles of the 
walls, a web composed of loose threads, with but little ad- 
herence between them. The female agglutinates her eggs 
into a round naked body, which she carries between her 
mandibles. 
M. Dufour has found a second species, Pholqiie a queue 
(Annal. des Scienc. Physique, V. lxxvi. 2.), in the clefts of 
rocks at Moxente, in the kingdom of Valencia. Its abdomen 
is terminated by a conical projection, thus forming a kind 
of tail, like that of the conical epeira. Like the preceding, it 
balances its body and feet. The palpi of the male have the 
genital organ extremely complicated. 
The third section of the sedentary rectigrade spiders, that 
of Orbiteles, has the external spinnerets almost conical, 
but little projecting, convergent, and disposed like a rosette, 
and the feet slender, as in the preceding. They differ from 
those in the jaws, which are straight, and sensibly w'ider at 
their extremity. 
The first pair of feet, and then the second, are always the 
longest. The eyes are eight in number, and thus disposed: 
four in the middle, forming a quadrilateral figure, and two on 
each side. 
They approach the Inequiteles in the size, the softness, and
