XsJ^UFQR 

 S. CAMPBELLI, Gray. PI. 5, fig. 46. 



Resembling S. vittatus in coloration, but with shorter spire, 

 the sutural band closely plicate, instead of smooth as in vittatus; 

 body-whorl smooth, except the revolving grooves at the base. 



Length, 2-2'5 inches. 



North and East Australia. 



Perhaps only a variety of S. vittatu*. 



S. DILATATUS, Swainson. PI. 5, fig. 47. 



Spire finely longitudinally plicate, all the whorls with close 

 spiral striae, no sutural band, interior of lip radiately ridged; 

 yellowish brown or light chestnut, with somewhat obscure 

 whitish maculations, and narrow bands, interstices of the ribs 

 on the inside of the lip, dark chestnut or purplish. 



Length, 2-2'5 inches. 



Zanzibar, New Caledonia, Japan. 



Reeve changed the name to S. Swainsoni, on account of S. 

 dilatatus, Lam. but the latter is a synonym of S. bubinius, 

 Linn. The shell figured by Lischke for S. Japonicus appears to 

 me to = this species. 



S. JAPONICUS, Reeve. PI. 5, fig. 48. 



Longitudinally finely ribbed towards the apex, everywhere 

 closely regularly spirally grooved, upper part of whorls slant- 

 ingly concave, with the angle obscurely nodose; whitish, 

 stained and variegated with chestnut, encircled with narrow 

 white zones sagittately marked with chestnut; interior white, 

 lip radiately ridged. Length, 2-25 inches. 



Japan. 



Closely allied to the preceding species, but is narrower, with 

 longer spire, the whorls are concavely shouldered, etc. 



S. COLUMBA, Lamarck. PI. 5, figs. 49, 50. 



Closely spirally grooved, spire longitudinally closely ribbed, 

 whorls concavely, slantingly shouldered, the angle tuberculated ; 

 variegated and banded with orange-brown and white, columella 

 and interior of outer lip both closely ridged, and stained deep 

 chestnut. Length, 2 inches. 



? Red Sea, Zanzibar, Philippines, Pelew Is. 



Differs from S. dilatatus by its ridged inner lip, angulated.
