cidedly shorter than the second, its eyes subeqiial, middle eyes shghtly 

 higher. Eyes of second row largest, less than their diameter apart. 

 Third row widest. Dorsal eye area less than one-fifth the length of 

 the cephalothorax. Quadrilateral of the posterior eyes longer than 

 broad. 



Form. — Cephalothorax in front truncated, about one-half its great- 

 est transverse diameter (?) or less (d^), highest at the posterior eyes, 

 the ocular region marked off by a groove from the cheek region. Sides 

 of head rather steep. Chelicera massive, much longer than the clypeus 

 wide, their length nearly twice the height of the head in front, with 

 3 pairs of teeth ; their posterior surface with a row of numerous trans- 

 verse striae. Sternum longer than broad. Legs long but strong, 

 length of the fourth to the cephalothorax in c? 4.1 : 1, in 9 3.6 : 1 ; in 

 the cJ^ the fourth metatarsus is slightly longer than the patella and 

 tibia combined. 9 palpal claw with 6 teeth. Anterior spinnerets

Color in Life. — Cephalothorax above grayish-black, with a grayish 

 median band that occupies the whole surface between the eyes of the 

 second and third rows, passes back to almost the middle of the cephalo- 

 thorax, there becomes narrower and continues to the posterior margin. 

 Extreme margin black. There is an interrupted submarginal gray 

 band which is continued on to the cephalic portion. All the gray 

 markings are due to long whitish hairs, and finer whitish hairs are scat- 

 tered over the blackish regions. Sternum thickly covered with long, 

 stiff, grayish hairs, sometimes black on the margins. Abdomen above 

 on its anterior half with a median band of dark brownish edged nar- 

 rowly with black and containing minute black spots ; this band termi- 

 nates truncated about the middle of the dorsum, and on each side of it 

 at about its middle is a pointed black spot. This band hes in a less 

 distinctly defined, broader pale brownish band which extends the whole 

 length of the dorsum and becomes much narrower toward the spinnerets. 

 In this broader band, behind the narrower enclosed darker one, are 

 about 6-7 crescentic transverse markings each as wide as the broad
