Remarks. — This superb species is the first representative of the circumscript genus Scceurgus to be 
noted from outside the Mediterranean and the immediately adjacent waters of the Atlantic, so that its 
occurrence as a common species in the Hawaiian Islands occasioned no little surprise. Not only does 
the present form belong unmistakably to this genus, but it presents so close an approximation to one of 
the Mediterranean species — S', unicirrus (delle Chiaje) — that the separation of the two has only been 
accomplished by attention to very small details. I have unfortunately not been able to see any actual 
specimens of S. unicirrus, but to judge from the figures given by Jatta (1896, p. 234, pi. 3, fig. 2; pi. 25, 
figs. 14-22; pi. 26, figs. 1-3) the body of the latter species is a little more elongate; the funnel organ is 
somewhat different in shape; and the ornamentation of the integument shows certain dissimilarities, 
notably in that no ridgelike folds are shown to occur on the dorsum and arms, although indications of 
such a fold on the third arms of the example figured on plate 26, figure 2, suggests the possibility that their 
absence in the other figures may be due to insufficient representation. The Hawaiian form also appears
