Length of the female $th of an inch; length of cephalo-thorax Pg; breadth A; 
breadth of abdomen yg; length of an anterior leg 4; length of a leg of 
the third pair +. 
This interesting spider has the cephalo-thorax oval, glossy, very convex above, 
and abruptly sloping in the posterior region, where there is an indentation 
in the medial line; along the middle extends a row of fine, curved bris- 
tles, directed forwards; its colour is pale yellowish brown, the lateral 
margins, and a triangular spot in the centre, which projects a line from 
the middle of its base to the eyes, and has a narrow triangle at its apex, 
whose base terminates at the medial indentation, together with a small 
triangular spot immediately behind each lateral pair of eyes, being black. 
Eyes seated on black spots on the anterior part of the cephalo-thorax ; the 
four intermediate ones form a square, the two in front being placed on a 
prominence; the lateral eyes are disposed in pairs on the sides of the 
square, those constituting each pair are contiguous and placed on a small 
protuberance. Mandibles powerful, conical, armed with a few minute 
teeth on the inner surface, rather inclined towards the sternu m, and of à 
dark brown colour, Maxillæ red-brown, with a dark brown mark on the 
outer side; they are pointed at the extremity and encompass the lip, 
which is triangular, black at the base, and red-brown at the apex. Ster- 
num oblong heart-shaped ; it is of a pale red-brown colour, with large, 
irregular, brownish black marks on the margins. Legs long and slen- 
der; there is a row of curved spines on the anterior side of the tibial, 
metatarsal, and tarsal joints of the first and second pairs, those on the 
metatarsal joint being much the longest ; both the legs and palpi are pale 
_ yellowish brown, with numerous dark brown bands. First pair of legs 
the longest, then the fourth, which a little exceeds the second in length, 
third pair the shortest. Tarsi terminated by three claws; the two supe
