S. angulata A. AD., P. Z. S. 1850, p. 34; Thes. Conch, ii, p. 

 842, t. 175, f. 57. SOWB., Conch. Icon., f. 10. 



A small species, intermediate in characters between S. duplicata 

 and S. rubra. 

 S. RUBRA Lamarck. PL 54, figs. 31, 32, 33 ; pi. 51, figs. 26, 27, 28. 



Shell depressed, with small, conical spire ; rather thin ; reddish 

 brown, lighter beneath, or variously variegated. Surface covered 

 with close fine hair-like spiral striae, and with two low keels above 

 the periphery, the upper one nodose ; there is a series of short folds 

 below the suture. Whorls of spire with a beaded carina ; last whorl 

 wide, depressed, flattened above, convex below, and impressed at the 

 axis ; aperture large, rounded, very oblique, iridescent within. 



Alt. 11, diam. 15? mill.; aperture, oblique alt. 9J, breadth 10

Differs from all the preceding in the more depressed body-whorl, 

 which is much like some species of Stomatella of the group of S. 

 mariei. The surface has very fine regular hair-like spiral striae 

 above. The following species seem to be very closely allied. 



S. LIRATA A. Adams. PL 54, figs. 23, 24. 



Shell orbiculate-con vex, provided with transverse subequal elevated, 

 slightly nodulose lirse, the interstices strongly longitudinally striate ; 

 subplicate at the sutures ; pale, radiately marbled with brown ; 

 spire rather prominent ; whorls rounded ; aperture oblique, oblong- 

 oval ; lip convex, rotund. (Ad.}

S. DECORATA A. Adams. PL 54, fig. 7. 



Shell Haliotis-shaped, orbiculate-depressed, covered-umbilicate;
