Diagnostic features. — The cirri are stout, curved throughout, with 24-50 short 

 subequal segments, which are two to three times as broad as long; dorsal spines are 

 developed before the eighth segment; the arms are up to 150 mm. in length; P 2 has 

 18-21 segments. 



Description. — The centrodorsal is thick discoidal, with a moderately large flat 

 polar area. The cirri are marginal and are arranged in one and a partial second 

 irregular rows. 



The cirri are XVI, 34-37, moderately stout, 20 mm. in length. All the segments 

 are subequal, about twice as broad as long, very slightly shorter basally and very 

 slightly longer distally. The sixth and following segments bear small sharp-pointed
