The _ascaris vermicularis_, thread, pin, or seat-worm, gives rise to most of the symptoms produced by the long worms, but in addition produces intense itching at the anus, and, not unfrequently, an eruption upon that part.
The _ascaris vermicularis_, thread, pin, or seat-worm, is round, very slender, and about half an inch in length.
