pale reddish or yellowish-corneous; very finely and evenly striate 

 throughout. Constriction in the middle in front. Last whorl smaller, 

 only moderately ascending to the aperture. Aperture subcircular, 

 the outer lip reflexed, duplicate, the two laminae close together, a 

 narrow opaque whitish streak just behind the reflection; indistinctly 

 angular at the base of the columellar lip. Parietal callus thin with 

 low, thread-like edge, not very distinct, and rising to the middle of the 

 front of the penultimate whorl. Columellar lamella horizontal, thin, 

 rather long. Palatal plica quite short and situated wholly to the left 

 of the parietal callus. Inside, the columellar lamella is evenly high and 

 thin throughout. Internal parietal lamella low and rather long. 



Length 3, diam. 1.5 mm.; whorls 6^.

 Hirase's collection. 



This species resembles D. nipponensis Mlldff. in shape and sculptm-e, 

 but differs by the position of the constriction, which is median in 

 gotoensis, above the termination of the outer lip in nipponensis. In the 

 latter species the palatal plica lies under the parietal callus. D. cassa 

 is a more cylindric species, the cone of the spire shorter. D. kyushuen- 

 sis Pils. and Hir., a widely distributed species in Kyushu, is closely 

 related to D. gotoensis, but it has a palatal plica about twice as long, 

 and the columellar lamella is much stronger near its inner termination 

 than near the aperture, while in D. gotoensis it is about equally strong 

 throughout. 



Eulota (Plectotropis) lepidophora soutifera P. and H., n. subsp. 



The shell closely resembles E. lepidophora tenuis Gude, but differs by 

 its more convex whorls and consequently deeper sutures. The 

 periphery is often a little less angular than in tenuis. Siu-face, when 

 unworn, copiously covered wdth triangular cuticular scales.

 1,2906 of Mr. Hirase's collection. 



Eulota (Aegista) celsa P. and H., n. sp. 



The shell is convexly conic, deeply umbilicate, the umbilicus cyhn- 

 dric, well-like, the periphery obtusely angular. Siu-face lusterless, 

 chestnut brown, finely but not strongly striate on the upper surface, the 

 striae indistinct at the base ; on the last part of the last whorl near the 

 aperture the striae are partially interrupted into long granules. The
