I. — On an Entozoon with Ova, found encysted in the Muscles of 

 a Sheep. By E. L. Maddox, M.D., H.F.K.M.S. 



{Bead before the Eoyal Microscopical Society, May 7, 1873.) 



Plate XVIII. and Upper Half of XIX. 



The following particulars, though scanty and imperfect, may be of 

 interest to Helminthologists as pointing to an unrecognized or at 

 least a very rare occurrence connected with the development of a 

 Cestoid parasite, found with ova, yet encysted, in the muscles of the 

 lower part of the neck of a sheep, and which was removed by myself 

 a few weeks since (April) from the exposed chop part of the joint, 



EXPLANATION OF PLATE XVIII. AND UPPEK HALF OF XIX. 

 Plate XVIII. 



Fig. 1. — One half of the small nodulated body found embedded in the musclea of 



a sheep, X 2. 

 „ 2. — Thin slice of the integument of the parasite, x 1G0. 

 „ 3. — Section of the ovarium, or may be vitelligene organ, compressed with 



immature ova and so-called calcareous corpuscles, x 160. 

 „ 4. — Small chitinous plate, x 160. 

 „ 5. — Hooks from proboscis of head, x 160. 

 „ 6. — Eight small spines, x 160. 

 „ 7. — Small narrow or denticulated pieces, x 160. 

 „ 8. — Larger smooth chitinous pieces, X 160. 

 „ 9. — Intromittent organ (?), x 160. 

 „ 10. — So-called calcareous particles, x 362. It is doubtful if the largest may 



not be an ovum in one stage of development. 

 „ 11.— A delicate cell filled with pale cells, X 362. 

 „ 12. — A little granular body or cell, covered with minute spines ; ? if one phase 



of development of ovum, or spermatic corpuscles, x 362. 

 „ 13. — Two granular cells, supposed to be the earlier stages of the ovum. 

 „ 14. — The well-formed ovum of the parasite marked as in trenia, x 410 ; the 



one below is figured at rather less magnification, and the lower 



ungranulated cell-like body appears to be similar, but arrested. 

 ,, 15. — Shows the mammillated condition of the integument, x 160. 

 „ 16. — Immature and mature ova of ordinary Taenia solium for comparison with 



Fig. 14, x 410. 

 „ 17. — Ideal figure of the entozoon. 

 „ 18. — Entozoon, nat. size, about. 



Plate XIX. (Upper portion). 

 1. — Head of entozoon, much compressed, mounted in Canada balsam, x 85.
