Notes on a Gregarine of the Earthworm (Lumbricus herculeus).

ABSTRACT While looking through some worms which had been obtained for dissection in Professor Ray Lankester’s laboratory at Oxford, Dr. Benham, Senior Assistant to Professor Lankester, noticed one specimen the hinder end of which appeared to be filled with small white bodies easily visible through the body-wall of the worm. These were preserved by Mr. E. A. Minchin, who identified them as a species of Gregarina, and by whose kindness I was allowed to examine them. As they presented some points of interest, perhaps these few notes may not be out of place.
