The Structure and Relationships of <i>Gnathostoma siamense</i> (Levinsen)

Abstract

The natives of Siam are occasionally affected by subcutaneous tumours that have been found to be due to the presence of a small nematode worm named by Levinsen (1889) Cheiracanthus siamensis . Only one description of the species occurs in literature, and as this, the original one, was based upon a solitary immature female it is necessarily lacking in many details.
