GLOSSARY OF TECHNICAL TERMS. 



Acephaline. — A gregariiie not possessing an epimerite at any stage 



of its life -history. 

 Acnidosporidia. — Term sometimes used to include Sarcosporidia and 



Haplosporidia. 

 Actinoinyxidia. — Cnidosporidia with large spores, trivalved membrane, 



and three distinctly visible polar capsules. 

 Adeleidea. — Coccidia in which the gametocytes are dissimilar in size 



and are associated with each other dm-ing the later part of trophic 



life. 

 Agamete. — An agamic spore or product of asexual reproduction. 

 Agamogony. — ^Asexual or agamic reproduction by equal, omequal or 



multiple division. 

 Agamont. — An asexual individual reproducing without conjugation or 



fertilization. 

 Amitotic division. — Direct division of the nucleus unaccompanied by 



the formation of a spindle of threads. 

 Amoebosporidia. — Term used by Hartmann to denote a separate class 



of Protozoa, in which are included Cnidosporidia, Sarcosporidia, 



and Haplosporidia. 

 Amcebula stage. — ^The sporoplasm which, by amoeboid movements, has 



left the spore membrane, a stage leading up to the schizont. 

 Anisogamy. — Conjugation between dissimilar gametes. 

 Anterior end. — The end of an organism which is habitually forward 



in locomotion. In Cnidosporidia the end of the spore from which 



the polar filament becomes extruded through the foramen. If 



the two extremities are dissunilar in form, the anterior end is 



usually more or less attenuate. 

 Association. — A group formed by the attachment of two or more 



sporonts. 

 Autogamy.- — Fusion of the two daughter nuclei to form a zygote or 



sporont. 



Biassociative.- — Referring to an association of two sporonts attached 



by imlike ends. 

 Binary fusion. — A mode of reproduction in which the division of the 



nucleus into two is followed by the division of the cell. 

 Budding. — The process of maequal fission, resulting in the formation 



of daughter organisms, which show a simplified structure when 



first formed.
