 Fig. 2. Portion of the mucous membrane of the lower extremity of the large intestine of Julus manj inn- 

 tut, with very numerous young thalli of Enterobryus eleyant. 

 a. Mucous membrane in outline. 

 I. Epithelia. 



c. Young thalli of Enterdbryus, in outline. 



d. Two thalli, with granular contents and a very few globules. 



Fig. 3. A single young thallus of Enterobryus ekgans, from the same position as Fig. '2, but more 

 magnified, so as to exhibit the contents. 



a. The primary cell, with granular contents and a few globules. 



b. The pedicle. 



Fig. 4. A single individual of Enterobryus elegant, from the ventriculus of Julus manjinalus, artificially 

 twisted, exhibiting well the appearance of the interior contents. 



a. The primary cell. 



b. Its watch-crystal like termination. 



c. The pedicle of attachment. 



PLATE III. 



Exhibits the structure of Enterobryus. 



Fig. 1. Distal portion of a primary cell, with an unusually short attached secondary cell of E. elegans. 



a. The portion of the primary cell filled with granules and globules. 



b. A secondary cell, filled with granules. The distal extremity of this cell is abruptly terminated, 



and the cell-membrane rises like the crystal of a watch from its dial. 



Fig. 2. Central portion of a primary cell distended with globules. A few very minute granules are 

 visible. 



Fig. 3. Proximal or attached portion of a primary cell. 



a. Portion of the primary cell; its lower end slightly dilated, filled with globules and granules. 



b. Portion of the pedicle. 



Fig. 4. Dilated distal extremity of a primary cell, filled with globules; the latter, in the upper portion, 

 polyhedral from pressure. 



Fig. 5. Central portion of the same cell containing granules and globules. 

 Fig. 6. Proximal portion of the same thallus. 



a. Portion of the principal cell filled with granules and globules. 



b. The pedicle. 



c. Its expanded basis of attachment. 



Fig. 7. Distal portion of a primary cell, filled with granules and globules, its upper end terminating 

 abruptly, with the cell-membrane rising like the crystal of a watch. 

 Fig. 8. Central portion of the same thallus, filled with granules and very large globules. 

 Fig. 9. Proximal portion of the same thallus. 



a. Portion of the primary cell, filled with granules mixed with a few globules. 



b. The pedicle of attachment, with four transverse contortions. 



c. Its expanded base of attachment. 



Fig. 10. Middle portion of a primary cell, very highly magnified, containing globules and granules. 

 Fig. 11. Proximal portion of the same individual as the last. 



a. Portion of the primary cell, with globules and granules. 



b. The pedicle, cut off below. 



Fig. 12. Distal portion of a primary cell, clavate in form, filled with granules and globules, and having 

 its summit crowned with a profuse bunch of Arthromitus. 



Fig. 13. Distal extremity of a primary cell of Enterobryus elegant, distended with a single row of large 

 globules.
