LINYPHIIDiE. 
one is inflected near its base. The palpi resemble the legs in colour, and have a slightly 
curved claw at their extremity. The abdomen is oviform, pointed at the spinners, very 
convex above, projecting over the base of the cephalo-thorax; it is thinly clothed with 
hairs, and of a yellowish-brown colour, freckled with numerous, minute, whitish spots ; 
along the middle of the upper part there extends a series of angular lines of a 
brownish-black hue, whose vertices are directed forwards, and whose greatly enlarged 
extremities form a row of very conspicuous, irregular spots on each side of the medial line ; 
several of the anterior angles are bisected by a fine, brownish-black line ; two longitudinal, 
irregular, brownish-black bands occur on each of the sides, the upper one being connected 
with the enlarged extremities of the angular lines by small, confluent spots of the same hue; 
a large, brownish-black band, whose anterior extremity is the broadest, occupies the middle 
of the under part, and comprises a yellowish-brown, medial line; the sexual organs are 
prominent, and have a brownish-black tint, with the exception of the extremity, which is 
flesh-coloured; and the colour of the branchial opercula is pale-yellow. 
The male, though smaller than the female, resembles her in the design formed by the 
distribution of its colours. The cubital and radial joints of its palpi are short, the former, 
which is the larger, having several long, curved bristles projecting from its extremity, in 
front; the radial joint is gibbous underneath, and has three short apophyses before, the 
middle one, which is the largest and darkest coloured, being transversely striated in front; 
the digital joint is somewhat oval, with a slightly curved, conical process at its base, in 
front; it is convex and hairy externally, concave within, comprising the palpal organs, which 
are highly developed, prominent, complicated in structure, with a slightly curved, pointed 
spine, and a finer one enveloped in a semitransparent membrane, at their extremity; they 
are of a red-brown colour. The convex sides of the digital joints are directed towards 
each other. * 
Both sexes of this spider, which bears a striking resemblance to linypliia cauta, were 
discovered in the greenhouse and melon-pits belonging to Mrs. Darbishire, of Green Keys, 
near Manchester, in September, 1836. 
In the account of Linypliia vivax given in the eighteenth volume of the * Transactions of 
the Linnean Society,’ a doubt is implied as to its being distinct from the Linypliia yloiosa of 
M. Wider (‘ Museum Senckenbergianum,’ B. i, p. 259, taf. 17, fig. 9); however, an attentive 
perusal of the description and an inspection of the figure of the latter have induced the 
conviction that they are different species.
