Differs from C. medius, above described, in having the plumose 

 bristles of the stridulating organ decidedly more slender and less 

 clavate and also more numerous. Bristles of legs and abdomen less 

 coarse, fewer in number and shorter. Anterior row of eyes less 

 procurved.

Integument of carapace, sternum, legs, and chelicerae when dry 

 black or nearly so, showing in parts a faint reddish tinge which is 

 more evident when specimens are immersed. Pubescence of cephalo- 

 thorax and appendages golden brown. On the legs the usual longi- 

 tudinal streaks of grey show above, especially on patellae and tibiae, 

 and across distal ends of joints is the narrow line of similar grey hair. 

 Bristles of legs of a more reddish cast proxijiially, dis tally becoming 

 greyish. 



Anterior row of eyes in dorsal view weakly procurved, a line tangent 

 to anterior edges of median eyes passing in front of middle of lateral 

 eyes. Anterior median eyes about equal to or scarcely larger than 

 the laterals as measured by long diameter; about their radius apart 

 and a little farther from the laterals. Posterior lateral eyes nearly 

 equalling the anterior laterals from which separated by a little less 

 than three fourths their diameter. Posterior median eyes very 

 much closer to the lateral eyes than to the anterior median eyes; 

 clearly smaller than the laterals; moderately elliptic. A line tangent 

 to the caudal edges of the two posterior eyes of each side touching or 

 passing very close to the anterior median eye of the opposite side. Eye- 

 area wider than long in ratio 48: 25.
