Remarks.— As the single specimen seems doubtless a very young one, there has been 
some natural hesitation about naming and describing it, but the possession of the curious 
posterior fold, a very singular feature in this group of cephalopods, and the excellent 
preservation of the creature^ seem decisive for the wisdom of this course. The longer 
body, much larger fins, and more anterior position of the eye amply distinguish this 
specimen from the Kermadec Island juvenal identified with his S. meangensis by Hoyle 
(’86, p. 65, pi. 9, figs. 12, 13), and I have encountered nothing else in the literature 
suggesting the necessity of special comparison.
