Abstract

The structure of the "tumor" on the brain of the stickleback fish, Eucalia inconstans (Kirtland) caused by Diplostomum baeri eucaliae, has been briefly reported (Hoffman and Hoyme, 1957; Hoffman and Hundley, 1957) and consists of an outgrowth of the columnar epithelium of the choroid plexus which surrounds the metacercariae at the postero-lateral aspect of the optic lobes. The present report deals with the experimental development of the "tumor."
No record of a comparable structure in fish could be found and the reader is referred to our earlier paper (Hoffman and Hundley, 1957) for further introduction, and materials and methods.
