Legs, 4123 ; aldiost equally stout.

The cephalic part is high with vertical sides ; there is a 

 deep constriction a little way behind the dorsal eyes, back of 

 which the thoracic part is level for a short distance, and then 

 slopes off, not very steeply, growing slightly narrower behind. 

 The quadrangle of the eyes is scarcely one-fourth wider than long, 

 is a little wider behind than in front and occupies two-fifths of 

 the cephalothorax. The anterior eyes form a row slightly 

 bent downward ; they are close together, the middle eyes 

 being about twice as large as the lateral. The second row is 

 nearer the first than the third row. The dorsal eye is slightly 

 larger than the lateral, and is placed on the side of the cephalo- 

 thorax. The pedicle is short. The abdomen is short, oval, 

 with a faint constriction in front of the middle. The falces 

 are long, with a very slight downward inclination ; they are 

 flattened above and on the inner faces, and the outer edges are 

 slightly, but evenly, curved outward from the insertion and 

 then inward to the extremity. The teeth are very small. 

 The fang is long and only slightly bent at the extremity. The 

 sternum is narrow. The lip is a little longer than wide. 



Color. The whole body is dark brown. The cephalo- 

 thorax is thinly covered with short, white hairs, and the abdo-
