Tanisui (Swinhoe); Anshiryosan, Hotawa and Suganiikei (Hirase). 



This species varies a good deal in size and structure of the hp, but 

 Schmacker and Boettger seem to be right in hokling that all the de- 

 scribed Formosan forms are but varying races of one species. The 

 specimens from Hotawa are about typical, length 13 mm. Those from 

 Anshiryosan seem referable to the race tnorrisonia H. Ad., described 

 from Mt. Morrison. They are 10.5-11 mm. long, and have the upper 

 funnel of the lip much smaller than in the type. At Suganiikei there 

 is also a small form of about the same length. 



The var. meridionalis S. and B. is distinguished by smaller size, 

 length 9.5 to 11, width 4^ to 4f mm. It is from Bankimtsong. The 

 type of P. morrisonia is 12 x 5 mm., while the size of typical P. swinhoei 

 is given as 14 x 5.5 mm. 



Diplommatina hungerfordiana NeviU. 



Jour. Asiat. Soc. Bengal, L, 1881, p. 150. Mlldff., Jahrb., IX, 349. 



Keelung (Hungerford) = Kiirun (Hirase). Dr. von Moellendorff 

 considered this a variety of the Chinese D. paxillus Gredler; but its 

 differential features seem constant, 



Diplommatina taiwanica n. sp. 



Shell imperforate, the lower half cylindric, upper half conic, light 

 orange colored, darker toward the apex. Whorls 6^, the first 4+ reg- 

 ularly increasing, the next whorl larger, swollen, the last whorl much 

 smaller, especially as seen in a dorsal view. First H whorls smooth, 

 the next 3^ sculptured with delicate thread-like riblets which become a 

 little closer on the front of the swoUen penultimate whorl, and then 

 become more or less obsolete, so that the last whorl or whorl and a 

 half are nearly or quite smooth. Constriction median above the aper- 

 ture. Palatal plica short, partly under the parietal callus. Aperture 

 vertical, irregularly rounded, the columellar margin straightened. 

 Peristome well expanded and somewhat thickened, angular at the 

 junction of the columellar and basal margins; parietal callus rather 

 small, its border usually indistinct. Columellar tooth small. 



Length 2.9, diam. 1.5 mm.
