Zoology’). Subsequent investigations, however, made with great care, have served to 
establish the fact that it appertains to the Agelenidce, as it possesses several marked 
characteristics in common with the spiders of that family; for example, the anterior part 
of its cephalo-thorax is compressed; the superior spinners are triarticulate, are longer than 
the rest, and have the spinning-tubes disposed on the under side of the terminal joint; each 
inferior tarsal claw is provided with two pairs of fine teeth near the base, and its web 
is of a compact texture, having a tube in connexion with it, extending usually to the extremity 
of a cylindrical cavity in the earth, which is frequently excavated by the animal itself. 
These facts do not appear to have received that degree of consideration from M. Walckenaer 
which their importance demands, as he still seems disposed to retain Ccelotes saxatilis in the 
genus Clubiona (‘ Hist. Nat. des Insect. Apt.,’ t. iv, pp. 441, 442). With regard to the genus 
Amaurobius of M. Koch, as it includes spiders belonging to dilferent families, which are easily 
distinguished by their organization, economy, and habits, it must, as at present constituted, 
be rejected by systematic naturalists. The great defect of the genera attempted to be 
established by M. Koch is, that they are founded too exclusively on the disposition, form, and 
relative size of the eyes; consequently, it sometimes happens that they comprise species 
in other respects decidedly incongruous. 
Ccelotes saxatilis pairs in April, and in May the female deposits about 120 spherical eggs, 
of a yellowish-white colour, not agglutinated together, in a lenticular cocoon composed of 
white silk, of a fine but compact texture, measuring half an inch in diameter; it is generally 
attached to the inferior surface of stones by a small covering of web, on the outer side of 
which particles of indurated soil are frequently distributed. 
Genus TEXTRIX, Sundevall. 
Eyes unequal in size, distributed on the anterior part of the cephalo-thorax in two 
transverse rows; four constituting the anterior row, which is slightly curved, are adjacent 
and minute^ the posterior row is greatly curved, having its convexity directed forwards, and 
comprises the other four eyes, which are large and separated by wide intervals, the two 
intermediate ones being the largest of all. 
Maxillce curved towards the lip, enlarged and rounded at the extremity. 
Lip large and nearly quadrate. 
Legs moderately long; the fourth pair is the longest, and the other three pairs are equal 
in length, or nearly so.
