The legs lue ])tilc whitish yellow, furnished with hairs and black spines, 

 those on the two fore i)airs of legs being the longest and strongest, ses- 

 sile, and arranged in pairs beneath the tibiae and metatarsi ; be- 

 sides these are several on the uppersides of the femora: each 

 tarsus ends with two claws, beneath which is a small scopula. 



The falces are strong, slightly projecting forwards, and a little prominent 

 near their base in front ; they are furnished with a few black bristly 

 and other hairs, and (except a small oval yellowish patch near their 

 inner extremities) are of a rich dark yellow-brown colour. 



The maxilla and labium (which are of normal structure) are also of a 

 deep yellowish brown, tipped with pale yellowish. 



The eyes are nearly of the same size and placed on slight tubercles, in 

 the ordinary position ; but there is scarcely any perceptible clypeus, 

 the fore central eyes almost touching the fore margin of the caput ; 

 the foremost row is much the shortest, straight, and equally di- 

 vided by the eyes of which it is composed ; the interval between 

 those of the hind central pair is rather greater than that between 

 each of them and the hind lateral nearest to it ; and the fore 

 central eyes form a quadrangular figure whose fore side is the shortest ; 

 the interval between each two eyes of the foremost row is about 

 equal to an eye's diameter. 



The normal grooves and indentations on the cephalothorax are nearly 

 obsolete ; that indicating the junction of the cephalic and thoracic 

 segments is marked by a short, deep, red-brown line. 



The sternum is heart-shaped, yellow, and has some red-brown macula; 

 on the margin, opposite the insertion of the legs. 



The abdomen is oval, of a dark, warm, purplish, red-brown colour, 

 streaked and marked with the normal pattern of pale reddish yellow, 

 and pretty thickly clothed with tine yellowish-grey hairs; the under- 

 side is of a more uniform purplish red-brown, with two parallel pale 

 reddish-yellow lines along its centre; these lines do not reach the 

 spinners. 



The epigyne connected with the sexual aperture is of large size and very 

 unusual and characteristic form ; it is very strong and broad, directed 

 backwards, and folded inwards at its extremity; the figure given (PI. 

 XIV. fig. 3) will give a better idea of this portion of structure, by 

 which the species may be known at a glance from others closely allied 

 in form, structure, and colour. 



A single adult female was kindly forvfarded to ine in 1872 by 

 Mr. J. W. Traill, of the University of Aberdeen.
