428 REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 
This species so exactly resembles Z. minuta, Bl. Brit. & Irish Spiders, part ii. p. 218, 
in size, form, general appearance, markings, and habitat, that the description given by 
Mr. Blackwall of the latter applies equally closely to the one under consideration, except 
in two or three respects. First, the dark annulation of the legs generally present in 
L. minuta is seldom strongly marked in Z. confusa, and most commonly absent alto- 
gether. Secondly, the palpi in the male differ slightly in the form of the digital joint and 
structure of the palpal organs, as shown in the figures of those parts of each species, and 
remarkably in the form and armature of the cubital joint of the palpi. In L. minuta 
(PL 55. no. 21 e) this joint has a small tubercular prominence near the fore extremity 
of its upperside, whence springs a slightly sinuous strong spiny bristle of equal strength 
throughout its length and obtuse at the end, or rather suddenly ending in a point. In 
L. confusa the cubital joint has no prominence on the upperside; but a fine-pointed 
tapering bristle, sometimes nearly straight, sometimes slightly sinuous, replaces the strong 
spiny one in L. minuta ; this difference is observable at a glance, and is very characteristic 
of the species. 
It is difficult to distinguish the females of the two species; buta slight difference exists 
in the structure of their respective external sexual organs (epigyne). A variety of the 
male of both species is not unfrequent, in which the abdomen almost entirely wants the 
dark markings. | 
L. confusa is abundant in the south of England inside old buildings, in their outer 
sheltered corners, among lichens, ivy, and in the interstices of the bark of trees, while 
L minuta is very rare, but found in similar localities in the north of England and in 
North Wales. Z.minuta appears to be the common species, and L. confusa the rare one, 
and consequently it was overlooked by Mr. Blackwall. It was, however, contained 
among specimens of L. minuta forwarded by Mr. Blackwall to the artist to be figured 
in his work on British and Irish Spiders, part ii, plate xv. 
LINYPHIA CINGULIPES, n. sp. (Pl. 55. no. 22.) 
Female adult, length 2 lines (4 of an inch). 
Cephalothoraz oval, not very convex above, of a dull greenish yellow-brown colour, 
marked with converging lines of a deeper hue following the normal grooves and inden- 
tations; ocular region very slightly prominent; clypeus prominent below, and slightly 
exceeding in height the length of space occupied by the four central eyes. 
Eyes in four pairs, or two transverse curved rows, of which the hinder one is rather 
the least curved; they are seated on black spots; those of each lateral pair are contiguous 
to each other and placed on a small tubercle ; those of the fore central pair are rather the 
largest of the eight, and the space between them is less than that between those of the 
hind central pair, though the transverse space occupied by each of these pairs is nearly 
equal; the spaces between those of the hind central pair and between each of those of the 
fore central pair and the fore lateral on its side are about equal, and an equal "n 
separates each fore central eye from the hind central on its side. -= 
Palpi moderately long, furnished with hairs, beetles, and afew spines. Colour dull :
