Note 13 — Chapter VI
Reading edition
An interesting Epistylis, called Digitalis, from its bells resembling fox-glove flowers in shape, occurs as a parasite upon the Cyclops quadricornis, a very common entomostracan in fresh-water ponds. At this moment I have a beautiful specimen, branching like a bushy tree, and attached to the tail of a Cyclops, who can scarcely move under his burden, which is like Sinbad's "Old Man of the Sea." (See illustration above.)
