Telson (text fig. 86) one and one-third times as long as broad at 

 its base, having the shape of a truncated triangle extending backward 

 about halfway along the inner uropods, apex truncate, armed with 

 one pair of long powerful spines about half the length of the telson,

 four spines confined to the distal quarter of the margin.

Type.— U.S. l<iM. no. 72869. 



Remarks. — The single specimen is badly damaged. All the thoracic 

 limbs are broken away, and the outer uropods are likewise broken. I
