Remarks
This shell was known as rare shell since Edo age in Japan. Therefore, it took 68
years from the first showing in Kigaizufu (1775) to showing in
Mokuhachifu (1843) next. The specimen shown in Kigaizufu of Kimura Kenkado
was Tamaoki Kiichi's collection. And the one shown in Mokuhachifu of
Musashi Sekiju was Tamaru Kansen's collection.
Thus, even authors who were ardent collectors were not able to collect this
shell by themselves. Body whorl can be weakly tied up usually.
However, the figured specimen is a little fat. The same type one as
this is drawn in Kigaizufu.
