Length of the female, ^th of an inch; length of the cephalo-thorax, 6?th|| breadth, ^nd;
breadth of the abdomen, ^ th; length of an anterior leg, gth; length of a leg of the third
pair, jth.
The cephalo-thorax is oval, convex, glossy, with an indentation in the medial line ; the
falces are conical, vertical, and armed with minute teeth on the inner surface; the maxillas
are straight, with the exterior angle, at the extremity, curvilinear. These parts have a brown
tint, with the exception of the lateral margins of the cephalo-thorax, which are black. The
lip is semicircular and prominent at the ap ex ; and the sternum is convex, glossy, and heart-
shaped. Both these parts have a very dark-brown hue. The eyes are seated on black spots;
those of each lateral pair are placed obliquely on a small tubercle, and are contiguous, and
the anterior eyes of the four intermediate ones forming the trapezoid are seated on a slight
protuberance, and are the smallest and darkest of the eight. The legs are long, slender,
provided with hairs and fine spines, and have a light, yellowish-red tin t; the first pair is the
longest, the second pair slightly surpasses the fourth, and the third pair is the shortest;
each tarsus is terminated by three claws; the two superior ones are curved and pectinated,
and the inferior one is inflected near its base. The palpi resemble the legs in colour. The
abdomen is oviform, pointed at the spinners, sparingly supplied with short hairs, glossy,
convex above, and projects over the base of the cephalo-thorax; it is of a dull, olive-green
hue, the under part being the darkest, and along the middle of the upper part there extends
a very obscure series of angular lines of a deeper shade, having their vertices directed
forwards; the sexual organs present two parallel, convex, glossy prominences of a red-brown
colour.
An adult female of this L inyphia was received from Mr. R. H. Meade in September, and
an immature one from the Rev. Hamlet Clark in October, 1853.

breadth of the abdomen, ^ th ; length of an anterior leg, T3Bth s ; length of a leg of the third
pair, ,th.
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 terminated
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 h u e ; 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 o f 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.
