Diagnostic jeatures. — This species is readily distinguishable from A'', 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 veiy 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.
