454 Mr. G. K. Gude on new Species of 



above, spirally wrinkled below. Spire convex-conoid, apex 

 obtuse, suture impressed. Whorls 5f, rather tumid, in- 

 creasing slowly, the last not descending in front, convex 

 below, narrowly impressed round the axis. Aperture ver- 

 tical, truncate-lunate ; peristome thin, straight ; margins 

 distant, columellar margin vertical, slightly reflected above. 



Two specimens. 



Diam. 2, alt. 1"75 millim. 



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



Allied to K. stenogyra, but it has fewer whorls than that 

 species and is rounded at the periphery. In shape it much 

 resembles a very minute Oanesella pagodula, Ehrm. 



Pyramidula (s. s.) pretiosa, sp. n. 



Shell umbilicate, discoid, corneous under an olivaceous 

 cuticle, distantly costulate. Spire depressed, apex obtuse, 

 suture rather deep. Whorls 3£, a little rounded, increasing 

 rather rapidly ; the last scarcely descending in front, angu- 

 lated at the periphery. Aperture roundly ovate; peristome 

 thin, straight, acute ; margins approaching, columellar margin 

 a little reflected over the narrow deep umbilicus. 



Ten specimens. 



Diam. 1^, alt. 1 millim. 



IJab. Fukura, Awaji Island. Type in my collection. 



Allied to P. amblygona, Reinh., but much smaller. 



Trishoplita Dacostce, sp. n. 



Shell deeply umbilicated, conoid, finely striated, obsoletely 

 decussated with microscopic spiral lines, perceptible only in 

 the depressions between the striaa, corneous, pellucid, rather 

 solid, shining below, duller above. Spire depressed, apex 

 obtuse, suture deeply impressed. Whorls 5-5£, rounded 

 above, a little flattened below, increasing rather rapidly ; the 

 last shortly deflected in front, rounded at the periphery, 

 widened towards the mouth and sloping into the umbilicus 

 behind the peristome. Aperture oblique, subrotundate ; 

 peristome scarcely thickened, slightly expanded all round, 

 the margins approaching, columellar margin a little reflected 

 over the deep but moderately wide umbilicus, which exhibits 

 the anterior half of the penultimate whorl. 



Two specimens. 



Diam. maj. 10 - 5-ll*5, minor 9-9'5 ; alt. 7-8 millim. 



Hab. Kagashima, prov. Satsuma. Type in my collection. 



Allied to T. conosptra, Mts., but more solid and with wider
