LINYPHIA.

The eyes are seated on black spots; the four intermediate ones form a trapezoid whose 
anterior side is the shortest, and those of each lateral pair are placed obliquely on a minute 
tubercle, and are contiguous; the posterior eyes of the trapezoid are the largest, and the 
anterior ones the smallest of the eight. The cephalo-thorax is oval, convex, glossy, with 
slight furrows on the sides converging towards an indentation in the medial line; the falces 
are conical, armed with a few small teeth on the inner surface, and somewhat inclined 
towards the sternum, which is broad and heart-shaped; the maxillae are enlarged where the 
palpi are inserted, and slightly inclined towards the lip, which is semicircular, and prominent 
at the apex. The legs are long, slender, and provided with hairs and fine spines; the first 
pair is the longest, then the second, and the third pair is the shortest; each tarsus is ter¬ 
minated by three claws; the two superior ones are curved and minutely pectinated, and the 
inferior one is inflected near its base. These parts are of a yellowish-brown colour; the 
sternum, lip, and lateral margins of the cephalo-thorax are the darkest, the legs much 
the palest, and the falces and maxillae are faintly tinged with red. The palpi resemble the 
legs in colour, with the exception of the digital joint, which has a brown hue; the cubital 
and radial joints are short, the latter being the stronger; the digital joint is oval, with a 
depressed, curved process at the base, on the outer side; it is convex and hairy externally, 
concave within, comprising the palpal organs, which are highly developed, prominent, with a 
black, filiform spine at the extremity, curved in a circular form, and are of a red-brown 
colour. The convex sides of the digital joints are directed towards each other. The abdomen 
is oviform, pointed at the spinners, thinly clothed with hairs, glossy, convex above, and 
projects over the base of the cephalo-thorax; it is of a yellowish-brown colour, the under 
part being much the darkest; and has an obscure series of dark, angular lines, whose vertices 
are directed forwards, extending along the middle of the upper part; between the branchial 
opercula there is a rather prominent, transverse fold. 
In the autumn of 1853 males of this species, having their palpal organs fully developed, 
were discovered among herbage growing in woods about Oakland.
