Very good figures have been given by Hombron and Jacquinot, 

 and by von Martens. It is well distinguished from interruptus 

 Miill. by its more ventricose form, larger aperture and thinner sub- 

 stance. The broad, more or less zigzag stripes and interrupted 

 peripheral golden band are also characteristic, though much reduced, 

 or even absent in some specimens. About half of the shells before 

 .me are sinistral. The young (fig. 67) are either uniform yellow or 

 have narrow bands at the suture, above and below the periphery, and 

 around the columella. Figures 66-68 reproduce von Martens' illus- 

 trations of specimens from Makassar. Figs. 69, 70 are further 

 color-patterns in coll. Acad. Nat. Sci. 



A clear yellow form, with no flammules, but with a narrow dark 

 varix on the penultimate whorl, and a dark-edged lip, is also illus- 

 trated, pi. 53, figs. 73, 74. This forms a transition to typical 

 perversus in color, but has the inflated contour and narrowly 

 recurved lip of sultanus, and is connected therewith by specimens with 

 sparse stripes (figs. 71, 72), referable to var. mitra. 



Var. MITRA (von Martens). 



Shell short, of conic figure, beautiful golden yellow with broad 

 reddish chestnut-brown stripes which rarely extend upon the upper 

 portion of the last whorl ; there is a more intense golden yellow 

 band, which, however, is not sharply defined at the edges. Length
