102 HELIX-EUHADRA. 



convex, the last about equally convex above and below, descending 

 in front. Aperture very oblique, truncate-ovate ; peristome pale 

 flesh color, showing the bands, margins converging, the upper 

 narrowly expanded, the basal more broadly reflexed, thickened ; the 

 umbilicus rapidly narrowing, the antepenultimate whorl not visible 

 within it. Alt. 19, greater diam. 33, lesser 26 mill.

This form holds the same relation to H. peliomphala that perryi 

 bears toward qucesita. It should probably be considered a color-race 

 of the protean peliomphala. "With H. simodce, the present species 

 has nothing to do. The conic spire and rapidly narrowing umbilicus 

 show it to be allied to peliomphala. 



H. SENCKENBERGIANA Kobelt. PI. 28, figS. 10, 11. 



Shell large, broadly umbilicated, orbicular-depressed, solid, striate, 

 very minutely granulatecf under a lens ; reddish-brown, with irregu- 

 lar yellow streaks in the direction of growth-lines, interrupting the 

 three dark bands. Whorls 5J, rounded, slowly increasing. Aper- 

 ture broadly lunate ; peristome reflexed, thickened, margins joined 

 by a thin callous, livid purple ; throat showing three bands on a 

 lighter ground. (Kob.} Alt. 30, greater diam. 56, lesser 47 mill.

This form also may prove to be a variety of H. peliomphala, with 

 which it agrees in all its characters except the larger size. It has a 

 great resemblance to the H. (Campylasa) pouzolzi of Europe. 



VARIETY (pi. 28, fig. 12). A form referred by Kobelt to sencken- 

 bergiana is figured. This shell is dark greenish-brown, with a 

 peripheral band, having scarcely visible light bands above and 

 below it. % 



H. NIPPONENSIS Kobelt. PI. 29, figs. 3, 4 ; pi. 41, figs. 4, 5. 6, 7. 



Shell depressed, with colloidal spire ; umbilicate ; sculptured with 

 strong, unequal thread-like whitish striae on a ground of straw- 

 color mottled and clouded with chestnut.
