OYOLOPHORID^. 

 Cyclophorus turgidus Pfr. 



Hotawa (Hirase). Has also been reported by E. A. Smith from 

 Formosa, without exact locaUt}^, P. Z. S., 1887, p. 318. The specimens 

 taken by Mr. Okura are quite typical. It is a common Ryukyuan 

 species. 



Cyclophorus formosaensis Nevill. 



J. A. 8. Bengal, 1881, p. 148, based upon C. exaUatiis var. Pfr., Novit. Conch., 



II, pi. 68, figs. 14, 15. 

 C. formosensis Nev., MUdff., Jahrb. d. m. Ges., IX, 1882, p. 277. 



Keelung and Takohan (Hungerford). Suganiikei (Hirase). This 

 is probably to be regarded as a variety of C. turgidus. The specimens 

 taken by Mr. Okura are not quite elevated enough to be typical. 



Mr, E. A. Smith incidentally reports C. exaltatus from Formosa (P. 

 Z. S., 1887, 318). It is a well-known Hongkong species, and in view 

 of the excessively critical nature of the species of Cyclophorus of the 

 Sino-insular group, the specimens referred by Smith to exaltatus may 

 belong to C. formosaensis. Some forms given the rank of species in 

 the exaltatus group by von Moellendorff and others are distinguished 

 by only slight and elusive characters. 



Cyclophorus indicus Desh. is reported from Formosa by H. Adams, 

 P. Z. S., 1866, p. 146. 

 Cyclophorus moellendorflB Schm. and Bttg. 



Nachrbl. d. m. Ges., 1891, p. 191, pi. 2, fig. 9. 



South Cape of Formosa, in the mountains (Schmacker). Carinate, 

 with relatively small aperture. 



C. m. humicola Schm. and Bttg. 

 Nachrbl., 1891, p. 193. 

 South Cape, at the foot of the mountains (Schmacker). There was 

 a transposition of pages 192 and 193 in the Nachrichtsblatt which creates 

 some confusion with this form until understood. 



Cyclophorus friesianus Mlldff. 



Jahrb. d. m. Ges., 1883, p. 286. S. and B., Nachrbl. d. m. Ges., 1891, p. 



191. 



Ijakuli (Fries) ; Bankimtsong and Bagsa. Distinguished by having 

 numerous small carinse above and below the peripheral keel. 



Japonia zebra n. sp. 



Shell umbilicate, conic-turbinate, pale yellowish-corneous with num- 

 erous red-brown longitudinal stripes, waved below the periphery, and 

 about as wide as the light intervals. Surface glossy, with sculpture of 

 numerous spiral threads separated by rather wide intervals, and most of
