 The cirri are XVII. One cirrus, not quite tuil size, with 39 segments remains. This example

This specimen may be described as follows : 



1 he centrodorsal is very small, apparently truncated conical, the dorsal pole very 

 slightly convex, obscurely tubercular, 1.5 mm. in diameter; the cirrus sockets are arranged in 

 ten columns of two, more rarely three, each. 



rhe cirri are XXII, 37 — 40 (usually 37), 28 mm. to 32 mm. long; the segments 

 gradually increase in length to the sixth, which is about as long as broad, and after the ninth 

 gradually decrease so that after the nineteenth they become about twice as broad as long; 

 the terminal fifteen to eighteen segments taper gradually so that the last few segments are 

 very small; all thi ments have slightly overlapping ventral distal ends; after about the 



ninth segment the (listal dorsal ends of the segments become prominent, and in the outer half 

 ot the cirri the segments bear the characteristic high dorsal keels.
