The term _Shinkir[=o]_ is used in the meaning of "mirage," and also as
another name for H[=o]rai, the Elf-land of Far Eastern fable. Various
beings in Japanese myth are credited with power to delude mortals

represented in the act of exhaling from its mouth a vapor that shapes
the apparition of H[=o]rai.

_Hamaguri_,--a Japanese mollusk much resembling a clam. Opening its
shell, it sends into the air a purplish misty breath; and that mist
takes form and defines, in tints of mother-of-pearl, the luminous
vision of H[=o]rai and the palace of the Dragon-King.
