Differs from If. peliomphala in being of a chestnut brown color, 

 yellowish at suture, around the brown umbilical tract and on each 

 side of the distinct peripheral zone. 



Var. BRANDTI Kobelt. PL 28, figs. 15, 16. 



Shell similar to H. peliomphala but somewhat smaller, the spire a 

 little more elevated, the umbilicus rather narrower. Surface nearly 

 lusterless, sculptured as in the type ; ground-color yellowish or 

 corneous, almost wholly concealed by broad irregular obliquely de- 

 scending opaque white or buff streaks, which interrupt the three 

 blackish-brown spiral zones, making them appear as spots or streaks. 

 Umbilicus dark inside ; lip broadly expanded of a pinkish-purple 

 color. Alt. 17, greater diam. 26, lesser 23 mill., often larger. 



Interior of Niphon.

The specimens before me show this to be a form intermediate 

 between typical peliomphala and nimbosa. 



Var. NIMBOSA Crosse. PL 28, figs. 8, 9. 



Form and sculpture as in the closely allied H. peliomphala. Epi- 

 dermis deep brown, with oblique, irregular yellowish streaks ; aper- 

 ture violet-brown inside, the peristome the same color. 



Alt. 16, greater diam. 35, lesser 31 mill.

Probably as von Martens says, a color-variety of H. peliomphala. 



H. HERKLOTSI Martens. PL 26, figs. 10, 11, 12. 



Shell rather narrowly urnbilicated, conoid-depressed, subgradate, 

 rough-striate and most subtly spirally lined, buff, painted with 3 

 chestnut bands, the middle one narrow, the upper double, the lower 

 triple its width, the upper edge of the upper band and the lower 

 edge of the basal one fading into the ground color. The umbilicus 

 is only a trifle darker than the rest of the shell. Whorls 5-1, a little
