LINYPHIIDiE. 
the sides converging towards an indentation in the medial line ; the falces are conical, armed 
with a few teeth on the inner surface, and inclined towards the sternum, which is broad, 
convex, glossy, and heart-shaped; the maxillae are straight, with the exterior angle at the 
extremity curvilinear; and the lip is semicircular and prominent at the apex. These parts 
are of a brownish-black hue, the falces and maxillae being faintly tinged with red. The four 
intermediate eyes form a trapezoid whose anterior side is the shortest, and those of each 
lateral pair are seated obliquely on a tubercle, and are nearly contiguous; the anterior eyes of 
the trapezoid are placed on a slight protuberance, and are the smallest and darkest of the 
eight. The abdomen is oviform, glossy, thinly clothed with hairs, convex above, projecting 
over the base of the cephalo-thorax, and is of a brownish-black colour, that of the sexual 
organs being reddish-brown. Some individuals have an obscure series of slightly angular 
lines of a pale-brown hue, whose vertices are directed forwards, extending along the upper 
part of the abdomen. 
The sexes closely resemble each other in colour, but the legs of the male are longer and 
have a yellower tint than those of the female. The radial joint of its palpi is stronger than 
the cubital, and somewhat produced in front; the digital joint is oval, with a lobe on the 
outer side; it is convex and hairy externally, concave within, comprising the palpal organs, 
which are highly developed, protuberant, complicated in structure, with a curved, prominent 
process near the base, on the outer side, a few very short, pointed ones at the extremity, and 
are of a red-brown colour. The convex sides of the digital joints are directed towards each 
other. . , 
Both sexes of LinypUa flavipes, in a state of maturity, were found among moss in woods 
at Oakland, in the summer of 1853; and in the spring of 1854, adult females were taken by 
the Rev. Hamlet Clark in Norfolk. 
Genus NERIENE {Blache.). 
Byes disposed on the anterior part of the cephalo-thorax in two transverse rows; the 
four intermediate ones describe a trapezoid whose shortest side is before, and those of 
each lateral pair, which are contiguous or nearly so, are placed obliquely on a tubercle. 
Maxilla strong, dilated at the extremity, and inclined or curved towards the lip. 
Lip semicircular, or truncated at the extremity. 
Leys moderately long and robust; the anterior and posterior pairs, which are the longest, 
are equal in length or nearly so, and the third pair is the shortest.
