with bristly hairs; digital joint irregular in form and (comprising the palpal organs) 
very large, nearly equalling in length the whole of the rest of the palpus ; palpal organs 
reddish-brown, very prominent, complicated, with a short slender spine at their extre- 
mity, curved in a circular form and in contact with a small mass of membranous matter. 
Falces moderately long and strong, rather gibbous in front near their insertion, and 
diverging laterally at their extremities ; similar to the cephalothorax in colour. 
Maxille long, strong, broad and rounded at their extremity, slightly inclined to the 
labium, similar in colour to the falces. ; 
Labium short, rounded at the apex, similar in colour to the sternum, which is broad, 
heartshaped, sparingly furnished with hairs, and of a yellow-brown colour, strongly 
suffused with dusky black. ; 
Abdomen oval, about equal in length to the cephalothorax ; its colour is nearly black ; 
the sides and upper extremity forwards are sometimes paler; a series of five, six, or seven 
strong angular markings, with the vertices directed forwards, and of a pale whitish 
colour, occupies the median line of the upperside; these markings diminish in size as 
they approach the spinners ; the first of them is often indistinct and sometimes obsolete, 
merging into a general paleness of the upperside near the front extremity: in some 
specimens these angular marks are interrupted at the angles. 
The female differs from the male only in being rather larger and in the usual structure 
of the palpi; her sexual organs are slightly prominent, but present no marked peculiarity 
in form. This species is closely allied both to Linyphia pulla (BL) and L. meadii (Bl.) 
and also to L. pullata (Camb.); it may easily be distinguished from Z. pulla by the 
much larger size of the digital joints of the palpi and palpal organs, and by the structure 
of the latter, as well as by the pattern on the upperside of the abdomen. From Z. meadii 
(the adult male of which I have never seen) the female may readily be distinguished by the 
absence of the large prominent process connected with the sexual organs, which is very 
characteristic of the female of L.meadii. L. approximata is larger than L. pullata, but 
resembles it in the general form of the digital joint of the palpi and palpal organs, which 
last, however, in L. pullata want the slender circularly curved spine at their extremity. 
Linyphia approximata was found abundantly at the end of May, 1863, among grass 
and sedge in a marshy spot at Bloxworth, low down among the stems of which it spins 
an irregular web. | 
LINYPHIA FURTIVA, n. sp. (Pl. 55. no. 20.) 
Male adult, length 4 of an inch (or 2 lines). Relative length of legs 1, 4, 2, 3. 
Cephalothoraz longish-oval, squared at the eyes; rises gradually from the hinder part 
to the eyes, where it slightly projects over the clypeus, which is of considerable extent. 
A small longitudinal indentation occupies the median line of the hinder part; and some 
slight furrows on the sides converge to this indentation. Colour dark-brown with a 
yellowish tinge ; ocular space furnished with some bristly hairs. 
Eyes eight, in four pairs ; those of the hinder pair are considerably wider apart than those 
of the front pair, and the largest of the eight; those of the side pairs are contiguous, and, 
as well as the front pair, placed upon tubercles; all are seated on black spots.
