The cephalothorax is oval, sides abrupt, roundly truncated in front; 

 lateral marginal constrictions at the caput slight ; it is of a light yellowish- 

 brown colour, sparingly clothed with light and dark hairs ; from the hind- 

 central eyes a lanceolate brown mark, with a light medial streak, extends 

 to the base of the cephalothorax ; on either side there are broad brown 

 marginal bands. The profile line rises abruptly from the thoracic junction, 

 then runs in a nearly even line to the ocular area. The height of the clypeus 

 exceeds the space between the eyes of the second row, and its direction 

 nearly vertical. 



The four posterior eyes are equal in size, and form a moderately re- 

 curved transverse row ; the other four form a trapezoid whose shortest side 

 is before, the posterior pair of the trapezoid are the largest, and the anterior 

 pair much the smallest of the eight. 



The legs are moderately long and slender, and do not differ greatly in 

 length, 1, 2, 4, 3, second and fourth nearly equal ; they are like the 

 cephalothorax in colour, and are marked with longitudinal streaks ; the 

 armature consists of hairs and long black spines. 



The palpi resemble the legs in colour and armature. 



The falces are subcylindrical, slightly inclined towards the lip, glossy, 

 clear pale brown ; dark brown streaks, apparently a continuation of those 

 on the frontal margin, extend along their entire length. 



The maxilla are long, somewhat enlarged and incurved at their extremity; 

 a shade darker than the falces, tinged on the outer side with brown. 



The labium is a long oval, dark brown. 



Sternum broad, cordate, convex, reddish brown. 



The abdomen is oviform, rises abruptly from the petiolum, which is 

 rather exposed ; its colour and markings resemble the cephalothorax ; a 

 light, broad, tapering mark extends from the base to the spinnerets, in the 

 centre there is an acute mark, formed by two dark streaks — in many 

 examples, both male and female, the lanceolate marks are partly obliterated 

 by whitish hairs— the lateral margins are dark brown, with a few light 

 oblique streaks. Ventral surface light brown. 



The vulva is a simple greenish-brown lobe, with two brownish spots at 

 the orifice. 



The male nearly equals the female in length, and does not differ essen- 

 tially from her in form or colour. The superior claws of the tarsi are finely 

 curved, and have about 18-20 parallel comb-teeth ; the inferior claw ter- 

 minates in a long fine, rather straight point, and has three long curved 

 teeth. 



The palpi are moderately long, the radial joint is blackish brown, rather 

 atouter than the cubital, and projects a concave apophysis on the outer
