THOMISIDiE. 
frequently attached to the inferior surface of a stone or fragment of rock ; it contains between 
eighty and ninety spherical eggs, of a pale, yellowish-white colour, not agglutinated together. 
This spider is found in Scotland and Ireland. 
A young female of this species, captured in July, 1835, had the two lateral pairs of eyes 
only ; the four small intermediate eyes were altogether wanting, not the slightest rudiment of 
them being perceptible even with the aid of a powerful magnifier.

The eyes are disposed on the anterior part of the cephalo-thorax, in two transverse, curved 
rows, forming a crescent whose convexity is directed forwards; the eyes of each lateral pair, 
which are seated on a tubercle, are larger than the intermediate ones, those of the anterior 
row being the largest of the eight. The cephalo-thorax is convex, compressed before, 
rounded on the sides, truncated in front, and depressed behind ; the colour of the sides is 
brownish-black, marbled with yellowish-white, a conspicuous spot of the latter hue occurring 
near the posterior extremity of each; the narrow, lateral margins, and a broad band extending 
along the middle, have a yellowish-white tint, the latter being contracted near its base. The 
falces are short, strong, subconical, and vertical; the maxillae are powerful, convex near the 
base, and inclined towards the lip, which is somewhat oval; and the sternum is heart-shaped. 
These parts are of a pale, yellowish-brown colour, spotted with darker brown, and the base of 
the falces and lip has a brown hue, that of the latter being the darker. The legs are provided 
with hairs and some strong spines, two parallel rows of the latter occurring on the inferior 
surface of the tibiae and metatarsi of the first and second pairs, which are much longer and 
more robust than the third and fourth pairs; the first pair is rather longer than the second, 
and the third pair is rather shorter than the fourth ; each tarsus is terminated by two curved, 
pectinated claws, and the palpi, which are short, have a small, curved, pectinated claw at 
their extremity. These limbs are of a yellowish-brown colour, spotted with dark-brown, the 
extremity of the femora, genua, tibiae, and metatarsi, and the base of the tibiae of the third 
and fourth pairs of legs, having a brownish-black tint on the upper surface. The abdomen is 
thinly clothed with hairs, moderately convex above, broader at the posterior than at the 
anterior extremity, which appears as if cut in a straight line across, and projects over the base 
of the cephalo-thorax; it is of a pale, yellowish-brown colour, tinged with olive and spotted 
with black, the spots on the sides forming oblique row's, and those on the under part being
