Iicad of tl)e male is higli and rounded and witliout liuni))s, and the 

 eyes are near each other on the npper part. Fig. I. The palpal 

 organ is very distinct from the allied species. The tube is like that 

 o{ jissice.ps ^ but the tooth at its base is much stouter and blacker and 

 the uppper portion of the bulb is stouter and blacker and has a long- 

 black tooth that extends nearly to the base of the slender tube. The 

 tarsal hook is short and stout. Plate 7, figs. Ic/, Ic. The epigynum 

 is darker and wider than mfissiceps. Fig. \d.

Length, 1-5""". Color light orange, the thickened circle on the 

 abdomen very distincl, and more deeply colored than the parts 

 around it. The head is black and a black line extends backward 

 half the length of the thorax. The latter mark is found in both 

 sexes and distinguishes the females of this species from eniertoni, in 

 which the black color is confined to the neighborhood of the eyes. 



The head of the male is extended forward over the mandibles, 

 carrying the front middle eyes, and has a hump above it with the 

 hind middle eyes. Figs. 2a, 2b. The female has slight humps on 

 the head. The epigynum is narrow and easily distinguished from 

 that of emertoni which it resembles in size and color. The palpal 

 organ is shown in fig. 2c. The slender spiral tube, with a black 

 tooth at the base, resembles that of C. alticej^s. The tibial hook is 

 slender and has usually a short tooth near the base. Fig. 2. The 

 tarsal hook is nearly straight and lies against the tarsus as in the 

 two nearest species.

This species resembles fissiceps so closely that for a long time I 

 thought it a variety of that species. The colors are the same and it 

 is of the same size or slightly larger. The two humps of the head 

 are swelled at the top and black. The lateral pairs of eyes are also 

 raised on smaller humps on each side of the head. Figs. 3, 3«. The
