ABSTRACT
Our doubts respecting the migrations of the Entozoa are justified to some extent by those which have been expressed by the two most celebrated French helminthologists themselves. Nevertheless we have not ventured to bring them forward without long and laborious critical study and experiment.
That we should not be suspected of partiality, wc borrow from a work composed with the greatest care what is said respecting Tœnia serrata. It is derived from—1. Cysticercus pisiformis, according to Kiichenmeister, V. Beneden, V. Siebold, Baillet ; 2. C. lenuicollis, according to V. Siebold; 3. C. cellulosœ, according to V. Siebold ; 4. Cœnurus cerebralis, according to Haubner ? V. Siebold, V. Beneden, Eschricht, and Leuckart. (DAVAINE. Entozoaires, Synopsis, p. 34.)
