This si^ecies is very close to C rubra, Keys. The epigynum is 

 about the same shape, the cavities are quite distinct, more so than 

 in my specimen of C. rubra ; the $ palpi are also similar to that 

 species. The coloring is the same, except the cephalothorax is a 

 little darker and the mandibles sometimes nearly black ; abdomen 

 in one specimen wholly gray, but usually with the red basal stripe 

 and the red tip to abdomen. The smallest i? is 4 mm, long ; the 

 smallest 9 is almost 5 mm. ; others are larger. The femur of the 

 $ palpus has two spines near the tip as seen in figure. 

 Frequent. Fall Creek, Inlet Marsh.
