436 REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 
Abdomen. Colour light-yellowish drab, very thinly clothed with hairs ; in one specimen 
some dusky transverse slightly angular lines were visible on the hinder half; a few of 
these near the spinners and on the underside were more conspicuous than the rest. On 
the underside, before each spiracular plate, is a patch of a yellow-brown colour. 
The female resembles the male in colour; but the relative length of legs is different, 
as noticed above; the abdomen also is much larger and more arched on the upperside, 
and the falces are more divergent; a large, strong, prominent, perpendicular and rather 
complex process is connected with the sexual organs, by which it may easily be distin- 
guished from the greater number of allied species. | 
Two adults of each sex were captured, at heath-roots, at Bloxworth, in March 1867. 
Its general similarity in colouring and form &c. to some others (among which to L. 
decens, n. sp., next described), makes it difficult to give a very distinctive description of 
this species; but from most others the eyes at once distinguish it, as well as the pecu- 
liar form of the corneous pieces connected with the palpal organs. 
LINYPHIA DECENS, n.sp. (Pl. 56. no. 27.) 
Male adult, length 7}; of an inch (1 line). 
Cephalothorax oval; the caput is not raised above the rest of the surface; looked at 
from the front it forms a segment of a circle, and in profile it slopes slightly forwards 
at the eyes. Divisional line of caput and thorax very indistinctly marked. Clypeus 
projects considerably ; its height is more than equal to double the distance between the 
two central pairs of eyes of the upper and lower rows. The cephalothorax is finely, 
completely, and thickly punetured on its surface ; the lateral grooves are slight, as also 
the longitudinal indentation on the hinder slope. A very few fine bristly hairs are on * 
the caput just behind the eyes, some longer converging ones on the clypeus, and several 
very short ones on the hinder slope. Colour of cephalothorax yellow-brown. — 
Eyes eight, in four pairs, forming two rows, which extend quite across the caput; all 
have more or less complete black rims; those of the central pair of the front row seated 
on a slight tubercle, are very minute, much the smallest of the eight; the remaining six 
are small, but not very unequal in size; . those of each side pair are contiguous, and 
placed obliquely on a slight tubercle; the fore ones are slightly larger than the hinder 
ones; the space between those of the central pair in the hinder row is double of that 
between each and the hinder eye of the lateral pair on its side, and equal to the space 
between the central pairs of each row. > 
Legs long, moderately robust, femora of the fourth pair the strongest; they are paler 
and clearer-coloured than the cephalothorax; relative length 4, 1, 2, 3; sparingly fur- 
nished with hairs and a very few slender spines, viz. one on the upperside of the fore 
extremity of each of the genual joints, and two on the upperside of each of the tibial 
joints; those on the hinder pairs are the longest and strongest, those on the fore pairs 
are but little more than fine bristly hairs. | | 
| Palpi short and of the same colour as the legs; the radial and cubital joints are about 
the same length, the former stout and slightly protuberant or produced at the extremity 
in front, round which it has a single row of bristly hairs projecting over the base of the —
