apex of the spine being intermediate in length between the submedian 

 and distal lateral spines of the telson. On its inner lateral margin 

 about two-fifths of its length from the base there is a rounded node, 

 resembling a blunted tooth. The outer branch of the process is only 

 about half as long as the inner spine but very acuminate and heavily 

 carinate on the inferior margin, this carina continuing along its lat- 

 eral margin to the base of the process. The inner branch of the 

 uropoda is very narrow, suboval, with the inner lateral margin 

 slightly concave, the outer slightly convex, and crenulate, the distal 

 margin rounded, extending almost as far as the outer lateral spine of 

 the telson; there is a definite longitudinal sulcus on the proximal 

 dorsal surface. The outer branch of the uropoda has the proximal 

 branch subrectangular, thick, with a strong median longitudinal 

 carina on the upper surface; the outer lateral margin carinate and 

 armed along its distal half with seven articulated sharp spines that 

 increase in length from the proximal to the distal one, which is at the 

 outer angle; midway the ventral surface of the distal margin there 

 is an eighth spine, fixed, protruding over the base of the distal article. 

 The distal article is unequally ovate, three-fifths as wide as long, with 

 the inner margin very convex, the outer lateral margin nearly 

 straight. This outer distal blade and the inner blade are both heavily 

 fringed with setae.
