Transversotrema haasi, a New Fish Trematode

Abstract

In a basin containing fish brought from the Red Sea about a dozen trematodes, which doubtlessly were parasites of one of these fishes, were found. As there were about twenty species of fish, it was not possible to determine the host. On investigation the specimens proved to belong to a new species of quite unusual structure, not fitting into any known genus or family. It is proposed to name it Transversotreicma haasi.1
