 converging lines ; abdomen ivith a pale yellowish-brown longi- 

 tudinal band down the centre of the upper side, slightly ramose, 

 and tapering to the spinners, a little above which are a few

Cephalothorax oval, compressed on the sides towards the 

 front. Colour palish yellow, slightly suffused with drab ; several 

 obscure brownish lines coumience near the eyes, and, running 

 back, meet at a small indentation in the medial line, where they 

 are met by some obscure converging rays which come from the 

 lateral margins. 



Eyes eight in nvimber, small, and seated on black spots on 

 the front part of the cephalothorax; the four centre eyes (of 

 which the two front ones are the smallest of the eight) form a 

 trapezoid with its shortest side forwards. The eyes of each 

 lateral pair are seated obliquely on a small tubercle, and are 

 contiguous. 



Legs long, slender, furnished with hairs and a few fine spines. 

 Colour like that of the cephalothorax, only rather paler, with 

 the tarsal and metatarsal joints darkest. Each tarsus ends with 

 three claws.

Falces poweiful, conical, a few teeth on the inner surface, 

 and rather inclined towards the sternum. 



MaxillcB strong, straight, the outer angle at the end curvi-

 white or pale cream-colour, the under side rather the darkest : 

 a light yellowish-brown band (with several small short branches 

 issuing obliquely from it across to the sides) runs from end to 

 end of the abdomen ; this band is broadest at the end near the 

 cephalothorax, and fines-down to a dark line before it reaches 

 the si)inners, just above which are six or eight small brown spots 

 in pairs; the first two pairs arc nearer together than the second
