Helicina hungerfordiana formosana Schm. and Bttg. 

 Nachrbl. d. m. Ges., 1S91, p. 186. 



Bankimtsong and Bagsa (Schmacker) ; Suganiikei (Okura). 



We quite agree with Schmacker and Boettger as to the very close re- 

 lationship of this to H. hungerfordiana of China. The Suganiikei spec- 

 imeiLS are a trifle less angular peripherally than Schmacker and Boett- 

 ger 's figure.

HELICID^. 



[Helix luhuana Sowerby has been reported from Formosa, specimens 

 identified by Cuming (P. Z. S., 1865, p. 197, No. 84). We doubt its 

 occurrence there. Helix melanostoma has been recorded from Formosa 

 in a list of Swinhoe's shells, identified by Cuming. ]\lr. Gude has al- 

 ready remarked upon this anomalous record.]
