ture of slight growth strhv and excessively close, deeply engraved 

 and minute spirals. Spire very slightly raised, narrow ; whorls 4|, 

 slowly increasing, the last much wider, double the width of the 

 preceding, rounded at the periphery. Aperture but slightly ob- 

 lique, rather broadly lunate, the peristome simple and acute, a 

 little retracted toward the insertion above, the columellar insertion 

 produced forward and a little dilated. 



Alt. 4.6, diam. 9.5 mm. 



Similar in general form to Helix rejecta Pfr., as figured by Rein- 

 hardt, 1 but miorograpta differs in the less oblique and less laterally 

 dilated aperture. No mention of spiral stria? is made in the de- 

 scription of H. rejecta. In H. donitzi Reinh. the last whorl is 

 conspicuously narrower, as seen from above. 



Kaliella multivolvis n. sp. 



Shell minute, imperforate, trochiform with convex base and 

 carinatecl periphery ; thin and subtransparent, of a brownish yellow 

 tint. Surface smooth, glossy beneath, a little less bright above. 

 Spire regularly and straightly conic; the apex obtuse. Whorls 

 6-J-7, the first rather large, the rest very narrowly revolving, 

 decidedly convex, the last whorl depressed-globose, with a rather 

 acute peripheral keel and quite convex base, which is narrowly 

 but rather deeply impressed around the axis. Aperture mainly 

 basal, shaped like a narrow, weakly curved crescent, with blunt or 

 truncate ends. Upon the base may be seen, in most specimens, 

 one or two nearly straight white radial stripes, produced by low 

 radiating barriers within, the last one often visible within the 

 mouth, upon the basal wall. 



Alt. 1.7, diam. 2.2 mm. 



Kashima, prov. Harima (Y. Hirase). 



Apparently allied only to K. stenogyra (A. Ad.), from Tsu- 

 Sima, described as a Conulus ; but the present species differs in the 

 strongly convex whorls of the spire. It is also smaller with fewer 

 whorls. The low radial ramparts within the last whorl are similar 

 to those of the American Conulus chersinus dentatus Sterki. 

 Some species of the little group Taxeodonta Pils. have internal 

 armature of the same kind. 



In K. multivolvis the barriers are placed at intervals of a third
