Eyes ( ? ). — First row as broad as the second, nearer the second 

 row than to the clypeal margin, its eyes equidistant, the middle eyes 

 shghtly larger and slightly higher. Eyes of the second row largest, 

 about their diameter apart. Dorsal eye area one-sixth the length of 

 the cephalothorax. Quadrilateral of the posterior eyes broader than 

 long. 



Form ( 2 ). — Cephalothorax highest at the posterior eyes and from 

 there gradually declining to its posterior margin, with the posterior 

 declivity barely demarcated from the dorsal, sides of the head oblique, 

 in front somewhat rounded and about three-fifths its greatest trans- 

 verse diameter. Chelicera with 3 pairs of teeth, their length almost 

 twice the height of the head in front, longer than the width of the cly- 

 peus, at their base almost as thick antero-posteriorly as one-half their 

 length. Thick scopulae inferiorly upon the four terminal joints of 

 legs I and II, and the two terminal joints of III and IV; leg IV to 

 cephalothorax as 2.7 : 1 ; metatarsus IV shorter than patella and tibia 

 combined.

 second row, somewhat shorter than the second, the lateral eyes slightly 

 lower and slightly larger than the middle and placed upon tubercles 

 so that they are directed downward. Eyes of second row largest, not 

 quite their diameter apart. Dorsal eye area to the length of the cepha-
