DESCRIPTIONS OF NEW HELICOID LAND SHELLS FROM JAPAN. 

 BY G. K. GUDE. 



Chloritis (Trichochlorites) pumila n. sp. 



Shell imperforate, depressed, dark coi'neous. Spire flat, apex 

 obtuse, suture iixipressed. Whorls 4:^, convex, increasing slowly 

 at first, the last widening rapidly; very densely covered with very 

 short bristles, arranged in oblique rows. Last whorl scarcely 

 descending in front, iuflated below. Aperture a little oblique, 

 rounded lunate, peristome thin, straight; margins distant, united 

 by a thin callus on the parietal wall. Columellar margin dilated 

 above, completely covering the umbilicus. 



Diam. maj. 12, minor 10.5; alt. 9 ram. 



Hab. — Mikuriya, Suruga (Hirase, No. 735). Type in my 

 collection. 



This makes the third species of Chloritis recorded from Japan. 

 It differs from both C. oscitans and C. fragilis by its smaller 

 size, by the completely covered umbilicus and by the bristles being 

 shorter, stiffer and much more crowded. In the shape of aperture 

 it is nearest to C. oscitans. 



Eulota (.Sgista) mimuloides n s)>. 



Shell rather narrowly umbilicated, depressed conoid, ruddy 

 corneous, paler below. Spire depressed, apex obtuse, suture linear. 

 Whorls 5, closely coiled, increasing very slowly, somewhat flat- 

 tened above, rounded below, with a thin deciduous cuticle, which 

 is densely covered with short silky processes, like adnate hairs. 

 The last whorl angulated at the periphery, scarcely descending' in 

 front. Aperture oblique, subcircular, peristome not thickened, a 

 little expanded; raai'gius distant, columellar a little dilated above. 

 Umbilicus rather narrow. 



Diam. 7.5, alt. 4.25 mm. 



Hab. — Itanami, Omi (Hirase, No. 753). 



Allied to JEgisia mimula, but it is smaller, the spire is more 

 depressed, the whorls are more closely coiled, the last is less ample, 

 the umbilicus narrower, and the cuticular processes are more 

 crowded and smaller.
