Some two years ago a proposal was put forward by Wenyon (1923) to change the name of one of the well-known coccidial parasites of man—the parasite which, in my revision of the group (1919), I called Isospora hominis (Rivolta). for various reasons Wenyon concluded that there must really be two species of Isospora in man—not one, as I had assumed—and he proposed to transfer my amended name I. hominis to another organism, whose existence he deduced from the literature and from his own observations on the Coccidia of cats and dogs: but as this would leave the species which I had called “I. hominis” without a name, he proposed to rename it “Isospora belli”.
