xoithout pale markings, in some specimens, however, much 

 paler ; sometimes exhibiting, as four very small pale dots upon 

 the dorsal area, the normal depressions in the integument 

 which indicate the points of attachment of the dorsal ventral 

 muscles ; following these on either side to the spinners are a series 

 of slender, oblique, pale lines. 



Legs stout, s/iort, dull yellow-brown, tinged in some specimens 

 with orange. 



Sternum pale sepia-brown. 



Caput broad and bluffly rounded, considerably raised behind 

 the eyes (fig. IV. 5). 



Clypeus higher than the width of the ocular area, quite 

 smooth, devoid of hairs and bristles. 



Eyes large, forming a closely situated group, the centrals 

 of both rows being slightly smaller than the laterals. Poste- 

 rior row slightly curved, its convexity directed backwards. 

 Central posteriors one diameter apart : lateral posteriors each 

 one and a half diameter from its adjacent central. 



Anterior row straight ; centrals smaller than laterals, very 

 close together, separate one quarter of a diameter. The lateral 

 anteriors each a little more than one diameter from its adja- 

 cent central. 



The four centrals form a trapezium whose anterior side is 

 much narrower than the posterior. 



Lateral eyes of both rows situated upon slightly raised 

 oblique tubercles (fig. IV. 5). 



Falces. — Basal joint much longer than the height of the 

 clypeus, very stout, convex and slightly divergent at the 

 apex; its outer surface finely striated ; without granulations, 

 denti dilations, or inner-frontal teeth. The upper margin of 

 the fang-groove is armed with five stout sharp teeth, the 

 three centrals being the longest. 



Labium much hollowed out, so that the upper margin is 

 strongly reflexed. 



Maxilla? as broad at the base as long, but longer than the 

 average breadth ; the outer margins obliquely rounded. 



Sternum as broad as long, terminating behind between the 

 coxal joints of the fourth pair of legs in a broad truncate 

 prolongation. 



Legs. — No spines upon the femora. 



Metatarsi shorter than the tibiae and without spines. 



Tibioz with two erect fine spines on the upperside ; genual 

 joint with one at its apex on the upperside. 



Palpus of Male. — Humeral joint of palpus long, cubital joint 

 without bristles, radial joint much enlarged on the upperside 

 and produced forwards over the base of the digital joint, form-
