Diagnostic jeatures. This species is readily distinguishable from N. europaea by 

 its more robust cirri, which are composed of more numerous segments, the longest of 

 which are only about twice as long as broad or very slightly longer; it is also much 

 larger. The cirri are XV-XXX (but rarely more than XX), 15-21 (usually 18-19); 

 the arms are 11-22 (usually about 15) in number, from 100 to 120 mm. in length.
