    Michaelsen (“Terricolen vonverschiedenenGebieten derErde,” Jahrb. Hamb. wiss. Anst. xvi.) has pointed out that the name PerichtBta, having been used for a genus of Diptera, must be dropped, and that the name Amyntas, formerly dropped on account of its being merely a synonym of Perichtsta, must be reinstated. Dr. Horst (Zool. Anz. 1900) traverses this conclusion, and would retain Periehmta for the worm, since it is not a valid dipteran genus.

  • It seems to me impossible to avoid the conclusion that a name once used cannot be used again for another genus.

    Here as elsewhere I give a list of localities from which the several species have been obtained. I believe, however (with Michaelsen), that the occurrence of the genus outside of the Oriental Region and Japan is accidental and due to man.

    It is often the ease that the dorsal ends of the sperm-sacs have a narrow knob-like projection. It seems to me to be merely a part of the sperm-sac which has not become fully expanded with semen. Iu the meantime, however, I mention the character where it has been noted.
