Japan (Van Nostrand). The Clanculus smithii Gray (=? C. 

 undatus Lm,), reported from Japan by A. Adams (before he had been

Japan (Dkr., Stearns). 

 Chrysostoma paradozum Born. Man. Conch., XI, p. 466. 



Mr. Stearns' specimen of this (No. 1186) may not be really Japan- 

 ese, although it was procured in Japan. 



Chlorostoma argyrostoma Gmel. Lischke, Jap. Meeres-Conch., I, p. 96, pi. 7, f. 

 4; PiUbry, Manual, p. 165. 



It is very doubtful whether this species occurs in Japanese waters. 

 The large example figured by Lischke, as well as the extensive suite 

 in the collection of the Academy, are from China. Lischke calls 

 the typical form of argyrostovium " var. major,^' but this term is 

 superfluous.
