nearer the clypeal margin than to the second row, middle eyes not 



quite double the size of the lateral. Eyes of second row largest, their 



diameter apart (J) or slightly more ( ? ). Length of the dorsal eye 



area to the cephalothorax, c? 1 : 6, 9 1 : 5.5. Quadrilateral of the 



.posterior eyes broader than long. 



Form. — Cephalothorax highest behind the middle (cJ*) or equally 



high there and at the posterior eyes ( 9 ), its posterior declivity abrupt 



and steep, in front truncated straight and less than one-half its greatest 



transverse diameter. Chelicera with 3 pairs of teeth, longer than the 



width of the clypeus, their length fully twice the height of the head 



in front. Labium longer than broad, truncated apically, not one-half 



the length of the maxillae. Sternum longer than broad, with few hairs, 



pointed posteriorly. Leg IV to cephalothorax, cJ' 3.5 : 1, 9 3.8 : 1; 



metatarsus IV shorter than patella and tibia combined. 9 palpal claw 



with 3 teeth.

Eyes. — First row nearer to the clypeal margin than to the second 

 row, its eyes equidistant, middle eyes larger and slightly higher. Eyes 

 of the second row largest, more than their diameter apart. Length 

 of dorsal eye area to cephalothorax as 1 : 5.5. Quadrilateral of the 

 posterior eyes broader than long. 



Form.— Cephalothorax highest at the posterior eyes, in front trun- 

 cated and fully ( 9 ) one-half or less (cJ') its greatest transverse diam- 

 eter, the sides of the head rather steep. Chehcera with 3 pairs of teeth, 

 as long as the width of the clypeus, their length more than twice the 

 height of the head in front. I>abium longer than broad, truncated 

 apically, not one-half the length of the maxillse. Sternum longer 

 than broad. Spinnerets equal in length. Length of leg IV to cephalo- 

 thorax, d^ 4.2 : 1, 9 3.3 : 1; in the 6" metatarsus IV is almost as 

 long as the patella and tibia combined, but shorter in the 9 . 9 palpal 

 claw with 4 teeth.
