Diagnostic features. The cirri have 18-20 segments of which the longest proxi- 

 mal are about twice as long as broad and the outermost are about as long as broad. 

 The arms are 80-90 mm. long. The edges of the elements of the IBr series and the 

 proximal and distal ends of the brachials are scarcely or not at all modified. P. 

 and P 2 are enlarged and prismatic with up to 26 segments. The distal ends of the
