 Siphonalia vanattai n. sp. PI. Ill, fig. 13. 



The shell is obcsely-fiisiform, the greatest width about median, solid 

 and strong; white, irregularly marked with dull purplish-brown spots 

 of irregular shape, and with narrow reddish-brown spiral lines, most 

 distinct behind the lip, six and equidistant or fewer by the omission of 

 some of them. Wliorls 6 (the protoconch being lost in the specimens 

 seen), longitudinally costate, 13 to 15 rounded ribs on the last whorl, 

 where they are most prominent at the shoulder, rapidly diminishing 

 below it, and not extending upon the base; sculptured throughout 

 with spiral rounded cords with threads occasionally interposed. The 

 last two whorls are subangular at the shoulder, the preceding whorls 

 being very convex. Last whorl is strongly contracted below. The 

 aperture is oblique, its length (including the anterior canal) about 

 two-thirds that of the shell, pale, dull, reddish-brown inside becoming 

 ochre-fleshy between the lirse, pure white on the bevelled edge. It is 

 rather sharply sulcate within. The outer lip is symmetrically arched. 

 Anterior canal deep and moderately recurved. 



Length 28, diam. 15 mm.; aperture to end of canal 19 mm. 



Length 26, diam. 13.7 mm. j aperture to end of canal 17 mm.

 of Mr. Hirase's collection. 



This small species resembles S. hinnulus in general contour and 

 coloration; but it is much smaller, decidedly plicate, and Urate within 

 the aperture. It does not seem to agree with any of the numerous 

 unfigured and insufficiently described forms introduced by A. Adams. 

 S. spadicea is more slender than S. vanattai. 



Twenty-seven species of Siphonalia are now recorded from Japan. 

 Of these, *S>. hyperodon Pils. is a synonym of S. mikado Melvill.^ S. 

 stearnsii Pils. is closely related to S. pseudobuccinum Melv., but seems 

 to differ by its shorter anterior canal. S. semiplicata Pils. is a syno- 

 nym of S. fusoides Rve., while S. longirostris Dkr. seems to be merely 

 a variety of the same species. Eleven species have been described 

 without figures by A. Adams. Omitting these, there remain about 

 fourteen recognizable Japanese Siphonalise.
