On new Species of Japanese Land- Shells. 453 



LVIII. — Descriptions of new Species of Japanese 

 Land-Shells. By G. K. Gude, F.Z.S. 



A further consignment of Helicoid land-shells received from 

 Mr. Ilirase contains seven undescribed species. 



I{aliella elata, sp. n. 



Shell subperforate, elongate-conoid, thin, fragile, sub- 

 pellucid, corneous, under the microscope seen to be covered 

 with about ten spiral lirse above the periphery, below minutely 

 spirally striated, shining. Spire elevated, apex obtuse, suture 

 slightly impressed. Whorls 6, compressed, increasing slowly ; 

 the last not descending in front, angulated at the periphery, 

 a little convex below, narrowly impressed around the axis. 

 Aperture a little oblique, subquadrate; peristome thin, 

 straight, acute ; margins distant, the columellar margin 

 vertical, slightly reflected over the narrow perforation. 



Four specimens. 



Diam. 1*5, alt. 2 millim. 



Hab. Kashima, prov. Harima. Type in my collection. 



Kaliella crenulata, sp. n. 



Shell imperforate, conoid, thin, fragile, subpellucid, pale 

 corneous, minutely ribbed above, shining and minutely striated 

 below. Spire conoid, apex obtuse, suture linear. Whorls 6, 

 flattened, increasing slowly, the last not descending; peri- 

 phery with a crenulate keel, convex below, narrowly im- 

 pressed round the axis. Aperture subvertical, subquadrate; 

 peristome thin, straight, acute ; margins distant, columellar 

 margin subvertical, slightly reflected above. 



One specimen. 



Diam. 2*75, alt. 3 millim. 



Hab. Kashima, prov. Harima. Type in my collection. 



Differs from its nearest ally K. acutangula, A. Ad., by the 

 flatter whorls, less convex base, and crenulated keel. It 

 is also nearly double the size, although having but half a 

 whorl in excess of its congener. Five specimens from 

 Kioto, previously referred to K. acutangula, prove to pertain 

 to this new species. 



Kaliella pagoduloides, sp. n. 



Shell imperforate, ovoid-conoid, thin, subpellucid, ochreous- 

 corneous ; under the microscope seen to be finely ribbed
