424 REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 
Abdomen oval, projecting over the base of the cephalothorax, very convex, and much 
elevated forwards. Upperside white with a central tapering brown band, commencing 
near the cephalothorax and continued more or less distinctly to the spinners, just above 
which it is at times enlarged into spots; the latter part of the band is sometimes a mere 
line ending with a conspieuous dark spot; on each side of this band is a longitudinal row 
of brown spots varying in size and conspicuity in different examples, in some almost en- 
tirely wanting, in others more marked towards the spinners than forwards; these spots 
are generally joined to the median band by fine oblique dark lines; below these rows on 
each side is a broad band of brown running backwards towards the spinners, strongest 
and best-defined forwards, and becoming more diffuse and less defined as it runs back; 
the under margin, however, is generally clear and well defined, and makes the white 
below form a very distinct white band, dividing the upper from the lower side of the 
abdomen. Underside dark brown, more or less regularly mottled and mixed with 
white ; the best-defined of the white markings is a circular line of spots in front of each 
spiraeular plate, and seven or eight well-defined spots forming a horseshoe round the 
spinners (the open part of the shoe being on the underside). In one specimen the upper 
margin of the underside towards the spinners was marked with some oblique bars of a 
darker brown, encroaching upon the white of the upperside. Sexual organs hairy, pro- 
minent, but simple in form, with no very conspicuous opening or epigyne. 
Adult and immature females of this species were captured by myself among sedgy 
grass in a swamp at Bloxworth in May, 1863. I could not succeed in discovering the 
male. It is something like Z. trilineata in colour and markings, but differs exceedingly 
in size and also in the relative position of the eyes. It is also allied to Linyphia 
albula (Camb.). 
LINYPHIA APPROXIMATA, n. sp. (Pl. 55. no. 19.) 
Male adult, length $ of an inch. Relative length of legs 1, 2, 4, 3. 
Cephalothorax oval, flattish ; cephalic region but little higher than the rest; i is in- 
dented in the median line of the hinder part, and has converging furrows on the sides ; 
it is of a yellowish colour, slightly clouded with dusky; and the furrows and lateral mar- 
gins in some specimens are indicated by indistinct sooty lines. 
Eyes eight, in four pairs, or two transverse rows; they are on black spots; those of 
each side pair are seated on a tubercle close together, but not touching; those of the 
front pair are the smallest of the eight and are much nearer together than those of the 
hinder pair, which are rather the largest of the eight; the front row is nearly straight; 
the hinder row slightly curved from the front. The clypeus projects beyond the eyes, and 
is higher than the distance between the front and hinder pairs of eyes. 
Legs dingy yellow, rather brighter in colour than the cephalothorax ; those of the first 
pair are slightly longer than those of the second, which last are but little longer than 
those of the fourth; they are sparingly furnished with hairs, and a few fine semierect 
spines. - 
Palpi short and of the same colour as the legs; radial joint rather longer and much a 
stronger than the cubital, slightly elongated in front and, with the digital joint, f A
