broadly rounded. The basal joints of the uropoda are large, being 

 partly covered by the terminal segment of the body. The outer 

 branch is styliform and extends its entire length l)eyond the terminal 

 abdominal segment. The inner branches are situated close together 

 in such a way that the inner lateral margins are continuous throughout 

 their length. 



The legs are ambulatory, similar, and subequal. 



Color brown, mottled with black. 



One specimen was collected by Dr. L. Stejneger at El Yunque, 

 Porto Rico, at an altitude of 2,800 feet.
