Remarks.— This superb species is the first representative of the circumscript genus Saeurgus 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
