This interesting spider has the eephalo-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 eephalo-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 sternum, and of a 

 dark brown colour. Maxillae 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 niimerous 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-
