Alt. 19, greater diam. 19, lesser 17 mm. 



Kyoto (Marshall R. Gaines). 



Closely allied to G. japoniea, and to some extent a transition 

 species betAveen the japoniea and the 'papillifonnis groups of Gan- 

 esella. It differs from G. japoniea in the greater elevation, com- 

 pletely rounded periphery and almost closed umbilicus. 

 Ganesella ferruginea n. sp. PI. XXI, figs. 14, 15, 16. 



Shell shaped much like G. japoniea, russet brown, paler near the 

 suture and outer lip, girt at the periphery with a chestnut band 

 bordered below by a corneous one; umbilicus pale corneous within. 

 Surface slightly shining, striatulate, seen under a strong lens to be 

 covered with a dense fine granulation, the granules point-like, in 

 places arranged in oblique rows sweeping nearly at right angles 

 with the growth lines, but on the base this arrangement is nearly 

 lost. Spire convexly conic; whorls 5^, the last rounded at the 

 periphery and beneath, hardly deflexed in front. Aperture 

 oblique, the lip expanded, thickened within, white; basal lip 

 refiexed, straightened, with a slightly convex caDus within; um- 

 bilicus deep, moderately wide, about one-third covered by the 

 dilated columella. 



Alt. 13, greater diam. 17J, lesser 16|mm. 



Okayama, Prov. Bizen (Gaines). 



Similar to G. japoniea, from which it differs in the russet color 

 nnd minute sculpture. 

 Ganesella heteroglypta n. sp. PL XXI, figs. 17, 18. 19. 



Shell somewhat trochiform, narrowly and almost closed umbili- 

 cate, thin, somewhat translucent, yellow-corneous, with a shght 

 olivaceous tint, a faint darker peripheral band, light-bordered 

 below. Surface with a dull silken lustre, produced by a clothing 

 of microscopic papillae or low elongated granules, irregularly and 

 densely placed. Spire elevated, with convex outhnes. Whorls 

 fully 6, moderately convex, swollen just below the sutures, Ihe 

 last whorl obtusely angular at the periphery, becoming rounded 

 on the latter portion, convex beneath, very slightly deflexed in 

 front, and constricted behind the peristome. Aperture oblique; 

 outer lip expanded, thickened within, basal hp refiexed, straight- 

 ened, calloused within; columellar lip very short, dilated, nearly 

 covering the umbilicus.
