X GLOSSARY. 



Cephaline. — A gregarine possessing an epimerite at some stage in its 

 life-history. 



Cephalont. — Young gregarine with an epimerite. 



Chitinous. — Corresponding in appearance and character to chitin, 



the horny material which forms the protective covering of insects 



and other Arthropoda. 



Gnidosporidia. — Sporozoa in which the spore is provided with one or 

 more thread-capsules. 



Coccidia. — Telosporidia in which the mature trophozoite is intra- 

 cellular and small, the zygote is non-motile, and the sporozoites are 

 developed within a spore. 



Coccidiomorpha. — -Term used by Dofiein to include Coccidia and 

 Hsemospor idia .

 or spores. 



Cortical. — Relating to the external layer of an organism. 



Cyst. — Impervious membrane surroim.duig an organism or a pair of

Cytoplasm. — The protoplasm of the cell-body as contrasted with that 

 of the nucleus. 



Cytozoic- — Parasites that are lodged inside a cell. 



Deutomerite. — The portion of a cephaline gregarine behind the septum,, 

 by which it is separated from the protomerite. 



Dicystid. — A gregarine in which the trophozoite is divided into two 

 parts only, that is, an epimerite is present, but the rest of the body 

 is not divided into a protomerite and a deutomerite.

Disporous. — ^Producmg two spores. 



Ectoparasitic. — Having the nature of an external parasite. 



Ectoplasm.. — The outer zone of the body of unicellular organisms, 



comprising the epicyte, sarcocyte, and myocyte.

develop independently of one another. 

 Encystment. — The phenomenon of becoming motionless and excreting 



a membranous cyst. 

 Endogenous or internal budding. — Formation of buds in the interior 



of the cytoplasm of the parent. 

 Endoparasitlc. — Havmg the nature of an internal parasite. 

 Endoplasyn. — The inner or granular zone of the body of unicellular 



organisms, lying within the ectoplasm. 

 Endospore. — The inner covering of a spore. 

 Epicyte. — The thm, fragile, external layer of the ectoplasm. 

 Epimerite. — The temporary, or rarely permanent, structure at the 



anterior end of a gregariiae by which the young gregaruae is attached 



to the host-cell. It is epicytal in origin. 

 Epispore. — The outer covering of a spore.
