404 PKOCEEDINGS OF THE ACADEMY OF 



ZONITID-EJ. 

 Kaliella subcrenulata n. sp. 



Shell narrowly perforate, depressed-trochiform, pale brown, 

 somewhat translucent. Sculpture of very fine, close, thread-like 

 striae and subobsolete spiral striae; the base smooth. Spire conic, 

 the apex obtuse. Whorls 4, nearly flat, the last acutely carinate 

 in the middle, the carina smooth-edged; base very convex. Aper- 

 ture narrow, somewhat rhombic; peristome simple. Alt. 1.5, 

 diam. 2.4 mm. 



Kochi, Tosa, Shikoku Island (Mr. Y. Hirase). 



Similar to K. erenulata Gude, but much more depressed. It 

 occurred with specimens of K. erenulata (Gude), and an elevated 

 variety of K. multtfbolvis Pils. 



K. ruida Pils. is a larger and more coarsely sculptured but 

 evidently allied species. 

 Kaliella lioderma n. sp. 



Shell perforate, pyramidal with flattened base, obtuse apex and 

 straight lateral outlines; pale yellowish-corneous. Whorls 7, 

 rather convex, the last acutely carinate, somewhat convex below. 

 'Surface glossy, smooth except for slight growth-striae. Aperture 

 basal, rhombic, nearly twice as wide as high; peristome simple, the 

 margins remote, the columellar margin reflexed. Alt. 2.5, diam. 

 2.2 mm. 



Kashima, Harima (Mr. Y. Hirase). 



More elevated than K. erenulata, and distinguished by its plain, 

 smooth surface. 

 Kaliella harimensis n. sp. 



Shell perforate, obtusely conoidal, fragile, amber colored, trans- 

 lucent. Whorls 5, convex, slowly increasing, the nucleus rather 

 large; last whorl obtusely subangular in front, elsewhere rounded 

 at the periphery, the base convex. Sculpture of extremely fine, 

 densely crowded, thread-like striae above, giving the surface a some- 

 what silken lustre; almost obsolete on the glossy 'base, which shows 

 weak spiral striae near the middle. Aperture truncate-crescentic, 

 the peristome thin, a little reflexed at the perforation. Alt. 2, 

 diam. 2^ mm. 



Kashima, Harima (Mr. Y. Hirase, No. 655). 



This species is much more depressed than the allied K. pagodu- 

 loides Gude. It has not the peripheral keel of K. fraterna Pils.
