Diagnostic features. There is no carination on the basal segments of the lower 

 pinnules. The arms are 19-39 (averaging about 25) in number, and are from 85 

 to 140 (averaging 112) mm. long. The cirri are XV-XXVI (usually about XX), 

 30-45 (usually about 35), and are from 16 to 30 (usually about 20) mm. long; the cirrus 

 segments are usually nearly or quite twice as broad as long. P 2 is from 7 to 15 (usually 

 about 11) mm. long, and is composed of 11-23 (usually about 19) segments; it is 

 usually very stout and abruptly and conspicuously larger than the other pinnules, but 

 in some cases it is only moderately stout. 



Description. The centrodorsal is thick discoidal, with the small polar area
