Legs, S and $ , 4, 3, 1, 2. The femur of the fourth leg is 

 enlarged, especially in the male. 



The cephalothorax is narrow and long — twice as long as wdde. 

 The sides are nearly parallel until the posterior quarter of the 

 thoracic part, where the cephalothorax grows abruptly narrower. 

 The cephalic part is on a higher plane than the thoracic and has 

 its sides inclined inwards. The thoracic part is rounded in its 

 anterior three-fourths, the posterior end, where it joins the abdo- 

 men, being flattened. There is a constriction at a little distance 

 behind the dorsal eyes. The quadrangle of the eyes is nearly 

 equally wide and long, is wider behind than in front, and occupies 

 about one-third of the cephalothorax. The first row of eyes is 

 strongly bent; the eyes are close together, the middle being twice 

 and a half as large as the lateral. The second row is nearer the 

 first than the third row. The dorsal eyes are larger than the 

 lateral and form a row which is as wide as the cephalothorax at 

 that place. The clypeus is narrow. The labium is wider than 

 long. The sternum is long and narrow. The abdomen is very 

 long and has a constriction in the middle ; it is narrowest in front, 

 tapering gradually toward the anterior end. The integument of 

 the anterior part is slightly hardened above, on the sides, and below. 

 The falces are moderately stout and long and are vertical. 



The cephalic plate and the anterior thoracic part are yellow, 

 with the eyes on black spots ; there are some white hairs on the 

 anterior part ; between the dorsal eyes are two fine dark lines ; 

 the rest of the upper surface is brown, darkening toward the pos- 

 terior end, \vith. a thin covering of white hairs, and having white 

 bards around the two constrictions. The spinnerets are light- 

 coloured. The legs are white or light brown, excepting the femoral 

 joints of the third and fourth pairs, which are rufous. The falces 

 are reddish. The pa] pi, mouth-parts, and coxae are white. The 

 sternum and venter are yellowish, the venter being blotched with 

 white.

2 . Length 3. Length of cephalothorax 1'3 ; width of cephalo- 

 thorax '8. 



Legs 4, 3, 1, 2, all slender. 



The cephalothorax is rather short, with a slight constriction just 

 behind the dorsal eyes. The cephalic part is flat, and is on a higher 

 plane than the thoracic which is rounded, and falls quite steeply 

 from the ridge behind the constriction. The sides are parallel. 

 The abdomen is rounded, and is widest behind the middle and 

 narrow at both ends. The clypeus is narrow. The quadrangle of 

 the eyes is one-fourth wider than long, is wider behind than in 

 front, and occupies about one-half of the cephalothorax. The first 

 row is curved ; the eyes are close together, the middle twice as 

 large as the lateral. The second row is halfway between the first 

 and the third. The dorsal eyes are larger than the lateral and are 

 on the sides of the head. The sternum is wide and is truncated
