CLUBIONA.

The eyes are seated on black spots, and disposed on the anterior part of the cephalo- 
thorax in two transverse rows; the posterior row is somewhat curved, having its convexity 
directed backwards, and the anterior row, which is the shorter, and situated a little above 
the frontal margin, is almost straight; the lateral eyes of the posterior row are the largest, 
and the two intermediate ones of the same row are the smallest of the eight. The cephalo- 
thorax is convex, thinly clothed with short hairs, slightly compressed before, rounded on the 
sides, and has a narrow indentation in the medial line; it is of a brownish-yellow colour, with 
a somewhat irregular, brownish-black band extending along each side, and narrow, lateral 
margins of the same hue. The falces are powerful, conical, rather prominent, armed with 
minute teeth on the inner surface, and have a pale, reddish-brown tint. The maxillte are 
straight, convex near the base, and rounded at the extremity; the lip is short and somewhat 
quadrate; and the sternum is oval, with small prominences on the sides, opposite to the legs. 
These parts are of a pale, brownish-yellow colour. The legs are moderately long, provided 
with hairs, and with two parallel rows of sessile spines on the inferior surface of the tibite and 
metatarsi of the first and second pairs, and are of a pale, brownish-yellow hue, with a few 
obscure, dark annuli; the fourth pair is the longest, then the first, and the third pair is the 
shortest: each tarsus is terminated by two curved, pectinated claws. The palpi resemble 
the legs in colour, and the digital joint, which is the darkest, has a small, curved, pectinated 
claw at its extremity. The abdomen is hairy, of an oblong-oviform figure, convex above, 
projecting a little over the base of the cephalo-thorax; the upper part is of a dull, yellowish- 
brown colour, with a longitudinal, black band in the middle of the anterior part, which 
gradually increases in breadth to its posterior extremity, and between this band and the 
spinners there is a series of angular lines whose vertices are directed forwards; the brownish- 
black sides are mottled with yellowish-brown, and the under part is of a dull, yellowish brown 
colour. 
According to M. Koch, the male is smaller and slenderer than the female, but its legs 
are longer in proportion to its size. The radial joint of its palpi is not so strong as the 
cubital, and is curved downwards; the digital joint is of an oblong-oval form, convex and 
hairy externally, concave within, comprising the palpal organs, which are moderately 
developed and uneven. 
The length of the adult female Philoica notata (Clubiona domestica ) is stated by M. Koch 
to be from four to four and a half lines. An immature female, captured in Gloucestershire in 
1852, was received from Mr. R. H. Meade, in the autumn of the same year; and in the 
autumn of 1858, the Rev. O. P. Cambridge took a young female in Dorsetshire. 
M. Walckenaer is certainly mistaken in supposing this species to be identical with 
Clubiona corticalis ('Hist. Nat. des Insect. Apt./ t. iv, p. 439), from which it differs in 
organization and colour. The males are very dissimilar, not only differing remarkably in the 
relative length of their legs, but also in the structure of the palpi and palpal organs. The 
genus Tliiloica of M. Koch, like some of the other genera which he has proposed for adoption, 
comprises spiders belonging to different families.
