GLOSSARY. XI 



Eugreqarinaria. — Gregarinida not showing schizogony. 

 Exogenous or external buddhig. — -Formation of buds from the external 

 surface of the body. 



Fission. — Division of the nucleus followed by a division of the cell-body. 



Gamete. — Specialized cells destined to meet and fuse in conjugation. 



Gametocyst. — The cyst formed round two associated sporonts or gameto- 

 cytes. 



Ganietocyte. — The mother -cell which gives rise to a number of gametes. 



Gamogony.- — -The process of prodiiction of gametocytes or gametes by 

 a gamont. 



Gamont. — An individual destined to form gametes ; also kiiown as 

 sporont. 



Glohidia. — Sarcosporidia in which the spores are fusiform and cysts 

 occur exclusively in the intestinal submucosa. 



Golgi apparatus. — A cytoplasmic inclusion which shows a tendency to 

 clunip together in masses or to form a network in the neighbour- 

 hood of the nucleus. 



Gregarinida. — Telosporidia in which the matiu-e trophozoite is extra- 

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

 developed within a spore. 



Gyninospore. — Naked germ or protoplasmic body, formed by sporulation, 

 which is not enclosed in a protective envelope. 



H'xmosporidia. — Telosporidia in -which the mature trophozoite is 

 intracellular and small, the zygote motile, and sporozoites are without 

 an envelope. 



Hsemosporidiidea. — Term used by Wenyon to denote Hsemosporidia 

 which form pigment in the red blood-cells. 



Haplocyta. — Gregarines in which the trophozoite is not divided by 

 an ectoplasmic septum. 



Haplosporidia. — Sporozoa characterized by possession of large spores, 

 and a simple type of development. 



Helicosporidia. — Cnidosporidia with small barrel-shaped spores, con- 

 taining a thick filament coiled beneath the spore-membrane and 

 three sporoplasms. 



Heteropolaridea. — Haplocite, producing sporocysts with dissimilar poles- 



Histozoic. — Parasites that occur in the spaces between groups of cells. 



Holozoic. — Animals which are entirely dependent for food on other 

 organisms, which they capture, devour and digest. 



Homopolaridea. — Haplocyta producing sporozysts with similar poles. 



Isogametes. — Gametes which are similar in shape and size. 

 Isogamy. — Conjugation between similar gametes. 



Karyogamy. — Union of two gametes whose nuclei undergo intermingling. 

 Karyosome. — A chromatic mass surroimded by plastin and contaiiaed 

 within the nucleus. 



Longitudinal striations.- — The very delicate ridges on the outside of the 

 epicyte.
