We are unable to find characters in the shells sufficient to separ- 

 ate the viridis (typical figures 49-52), calyculata, acuminata (figures 

 56, 57 " Guadaloupe and Sandwich Is."), and the glauca of Adams 

 (fig. 42) and of Sowerby (pi. 33, figs. 45, 46). It is doubtful whether 

 the glauca of Q. & G. will prove distinct. 



The species has also been reported from Pitcairn Island and 

 -Japan. 



Var. FASCIATA Sowb. PI. 33, figs. 54, 55. 



Shell oblong, subovate, compressed, semipellucid, golden-broWn, 

 spirally 3-banded, slightly contracted above the center; aperture 

 large, outer lip elevated, cuueate ; last whorl very narrow, append- 

 age long, acuminated. (Sowb.). 



Habitat unknown. 



Linteria fasciata SOWB., Conch. Icon., f. 5, 1870. 



S. GLAUCA Quoy & Gaimard. PL 33, figs. 43, 44. 



Shell a little more convoluted, more oval and more swollen above 

 than S. viridis ; sea-green. Animal about an inch long, the frontal 

 disc quadrate, wide, pointed at the sides in front, a little excavated 

 behind ; color of the entire animal apple-green, visibly peppered 

 with black, the mouth reddish, eyes black. 



Port Carteret, New Ireland. 



Bulla glauca Q. & G., Zool. Astrol. ii, p. 352, pi. 26, f. 10-12. 



Described from one individual the shell of which was not in good 

 condition. Adams and Sowerby have identified certain shells with 

 Quoy's species, but their decisions are not to be trusted. The real 

 distinctive characters are in the form of the frontal shield of the 

 animal, and this may be due to the temporary condition of the 

 individual seen by Quoy. The alleged conchological distinctions are 

 quite insufficient. 



S. MINOR A. Adams. PL 33, fig. 58. 



Shell small, pellucid, yellow, thin, smooth, oval, aperture very 

 wide, scarcely involute, longitudinally very finely, striated ; an un- 

 guiculate process at the spire. (Ad.'). 



Island of Zebu, Philippines (Cuming).
