This species is more nearly allied to H. ochthoplax Bens, than to 

 any other described form. It differs in the longer, nearly vertical 

 columella and other characters. 



H. saturnia has been placed by Albers and Pfeiffer in Phania; I 

 am confident, however, that it is a true Camcena (as that subgenus is 

 herein rehabilitated), and that when specimens are examined they 

 will show the large, distinctly marked nucleus (about one-fifth the 

 diameter of the shell, and composed of about 2 J whorls) characteristic 

 of that subgenus. I have not seen specimens. 



H. HAINANENSIS Adams. PL 21, figs. 53, 54. 



Shell dextral, elevated, globose, rimate, or almost closed perforate, 

 generally as high as wide or nearly so. Color greenish-yellow, with 

 numerous spiral bands and lines. 



The shell is globose, elevated and dome-shaped above, rather 

 flattened on the base. It is strong and solid, greenish-yellow with 

 numerous narrow bands and lines of dark-chestnut, and a narrow 

 blackish-brown girdle at the periphery ; the bands more numerous 

 above than below the periphery. The surface is shining, and all 

 over is closely finely corrugated by obliquely descending wrinkles, 

 becoming concentric on the base. AVhorls 5i ; apex obtuse ; earlier 

 whorls flattened, with superficial linear suture ; last whorl convex 

 just below the suture, rounded at periphery, not descending in front. 

 Aperture oblique, small, livid within ; peristome expanded, the 

 basal margin narrowly reflexed, the columellar margin suddenly 

 expanding into a reflexed triangular callus covering the umbilicus 

 except a narrow chink behind the lip. Margins of lip remote, con- 

 nected by a thin translucent sinuous callus.
