The surface under a strong magnification is seen to be very densely, 

 microscopically, irregularly granulate (this sculpture too small to be 

 shown in the figure), and set with low, rounded or oblong grains 

 arranged more or less obviously in oblique lines, in most places less 

 regular than where the figure was taken, on the upper part of the last 

 whorl, a short distance behind the aperture. The whitish apical whorl 

 seems to be slightly rugose, but not punctate. 



Chloritis tosanus osumiensis n. subsp. 



This form agrees in shape and color with C. tosanus, but it differs 

 in being smaller, with the hairs a little more widely spaced. The spire 

 is somewhat convex, with the apex turned down; whorls 4; lip thin 

 and sharp. 



Alt. 9, diam. 14.5 mm. 



Koneshima, Osumi. Types No. 87,339, A. N. S. P., from No. 1,248 

 of Mr. Hirase's collection. 



Koneshima is a place on the western coast of Osumi, on Kago-shima 

 Bay, about opposite the southern extremity of Satsuma. 



Ganesella tokunoshimana n. sp. 



Shell narrowly umbilicate, globose-conoid al, thin, the outlines of 

 the spire convex, apex very obtuse. Yellow, with (1) four black-brown 

 bands, a narrow one below the suture, a wide one at and above the 

 periphery, a narrower band midway between periphery and umbilicus, 

 and a fourth band inside the umbilicus, or (2) very pale reddish-brown 

 fading to yellowish near the suture and on the base, with a narrow 

 light band at the periphery. 



Surface glossy, the first 2 whorls smooth ; then faint growth-lines 

 and spiral striae appear ; these become progressively stronger, the last 

 whorl being covered with close incised spirals. Whorls 5J, convex, 

 the last but slightly or not deflexed in front, angular or subangular at 

 the periphery in front, becoming rounded on the last half or third, con- 

 vex beneath. The aperture is oblique, widely lunate, colored within 

 like the outside. The lip is thin, narrowly reflexed, white, at least at 

 the edge, dark at the ends of the bands, the columellar margin dilated. 



Alt. 21, diam. 26 mm. 



Alt. 22, diam. 26.2 mm. 



Tokunoshima, Osumi. Type No. 87,595, A. N. S. P., from No. 1,213 

 of Mr. Hirase's collection. 



This beautiful species stands close to G. adelince of Oshima and G. 

 sororcula of Kikaiga-shima, but differs from both in the obtuse spire, 

 the early whorls being depressed. It is less closely related to G.
