breadth of the abdomen, Ath ; length of an anterior leg, §th; length of a leg of the third 
pair, ~th. 
The cephalo-thorax is oval, convex, glossy, with slight furrows on the sides converging 
towards an indentation in the medial line; the falces are powerful, conical, vertical, convex 
in front, and armed with teeth on the inner surface; the maxillae are enlarged at the base, 
where the palpi are inserted, and inclined towards the lip, which is semicircular and 
prominent at the apex ; and the sternum is heart-shaped. These parts are of a dark-brown 
hue slightly tinged with red, the sternum, lip, and anterior part of the cephalo-thorax being 
the darkest. The legs, which are robust, have a red tint, and the anterior and posterior 
pairs are equal in length ; 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 cubital and radial joints are short, the former, which is the stronger, 
being convex in front; the latter has two apophyses at its extremity; one, situated in 
front, terminates in a point, and has a small, acute process on the inner side ; and the other, 
which occurs underneath, has a pointed process on the outer side; the digital joint is oval, 
convex and hairy externally, concave within, comprising the palpal organs; these organs are 
highly developed, complicated in structure, with a corneous process at the upper part, curved 
outwards, and are of a dark red-brown colour. The abdomen is oviform, convex above, 
projecting over the base of the cephalo-thorax; it is thinly clothed with hairs, glossy, and 
of a brownish-black hue; and the colour of the branchial opercula is pale yellowish-white. 
An adult male of this spider was discovered under a fragment of rock in a wood at 
Oakland, in June 1835.
