Diagnostic jeatures. — 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. P2 is from 7 to 1 5 (usually 

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

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

 in some cases it is only moderately stout.
