Not only is this simple type of endobasal body found in rhizopods and flagel- lates, but also in some cases in the more complex ciliates, where, in Chilodon cucullus, for example, the macronucleus contains a definite endosome which behaves exactly like that of Euglena. It is highly. Fig. 30. — Chilodon sp. Macronucleus with endosome and endobasal body (end). (mo) Mouth surrounded by pharyngeal basket. (Original.) B.
