as long as broad, outer margin terminating in a strong spine, which 

 projects slightly beyond the remainder of the scale so that there is 

 virtually no terminal lobe to the scale ; spine on the outer distal corner 

 of the basal joint of the scale very long and strong. 



(3) The telson (fig. 49, c) is very long and comparatively nar- 

 row, equal to the inner uropod in length, two and a half times as 

 long as broad at the base; apex narrow and truncate, two-fifths of 

 the breadth of the telson at its base, armed with four pairs of spines, 

 the inner pair the shortest and the outer pair the longest, equal in 

 length to one-eighth of the length of the telson; lateral margins

armed with 14 short spines, which occupy the distal three-fourths of 

 the margins, the most distal spine situated at the lateral corners of 

 the apex so that they almost appear to be part of the apical arma- 

 ture. I could not detect any median plumose setae at the apex but 

 they may have been broken off. 



(4) Inner uropod has a single long sharp spine on the inner mar- 

 gin near the statocyst. 



Type lot. — One male, 2 females, and the anterior ends of 2 additional 

 females, U.S.N.M. No. 81263, Albatross station 4400, off the coast of
