inside; peristome simple, unexpanded, the columellar mar-

Fully adult shells are wholly imp erf or ate with 7% whorls, 

 length 51, diam. 20.5, aperture 24 mm. The outer lip is very 

 thin and acute, and the suture very distinctly and finely 

 crenulate below. 



I feel very little doubt that A. subemarginata Desh. was 

 based upon a shell of this species. Its habitat was un- 

 known. 



2. S. CORONATUS (Pfeiffer). PL 37, figs. 89, 90. 



Shell imperforate, oblong-turrite, smooth, thin, diaphan- 

 ous, waxen-yellowish or whitish. Spire turrite, the apex 

 rather obtuse. Whorls 7, rather flattened, coronated with 

 close small whitish tubercles at the suture ; the last whorl 

 slightly more than one-third the total length. Aperture oval ; 

 peristome simple, acute, the columellar margin rather 

 straightened, flattened, appressed, reflexed. Length 21, 

 diam. 7.5, aperture 8x4 mm. (Pfr.).

Pfeiffer's figure, which I have reproduced (fig. 89) is 

 not very good, and an enlarged view is therefore given of 

 a specimen measuring 24.8 mm. long, 7.5 wide, aperture 8
