14 Prot. PROTOZOA. 
Temporary encystment on attack (Grenfell, J. G.)* 
Nervous system of Infusorians (Gruber, A.). 
Regeneration (Gruber, A.). 
Encystation “ protective ” distinguished from “ duplicative ” or “ sporu- 
lar” (Kellicott, D. S.). 
Roll of buccal apparatus of Euglence and Astasia (Khawkine, W.). 
Division and regeneration (Korschelt, E.). 
Zoo-amylum granules occurring in definite form in protoplasm of 
Gregarinids (Maupas, E.). 
Relation between reproduction and nutrition (Maupas, E.). 
Division, regeneration, and general notes on cellular physiology 
(Nussbaum, M.). 
Protamosba priniitiva (Ollivier, G.). 
Heliophagous function of “ eyes ” (Patten, W.). 
Subterranean Protozoa (Schneider, R.). 
Relation of flagellate forms to mode of life and environment ; frequent 
degeneration of flagella, no contractile vacuoles in parasitic and marine 
forms (Seligo, A.). 
Petalomonas : food-habit (Stokes, A. 0.). 
Reproduction. 
[See General Subjects.] 
Division of Dinoflagellates (Bergh, R. S.). 
Reproduction in Spharozoa (a) by division of colony, ( b ) by division of 
individuals, (cj by swarm spores (iso- and aniso-, with alternation of gene- 
rations [?]), ( d ) by budding off of “ extra capsular bodies ” (Brandt, K.). 
Lagenophry8. Divisiou (Butschli, O.). 
Monads. Reproduction (Dallinger, W. H.). 
Simple rupture-like division of Heterophrys dispersa (Dangeard, P. A.). 
Theory of reproduction (Geddes, P.). 
Conjugation of Paramceciam aurelia = intimate intermixture ; the 
nucleoli copulate with each other (Gruber, A.). 
Apparent conjugation of Amoeba (Holman, L. E.). 
Reproduction of Infusoria , &c. (Korschelt, E.). 
Ciliate Infusorians ( Colpodium, Paramcecium , Euplotes ), (Maupas, E.); 
interchange of nucleolar corpuscles in conjugation. 
Paramcecium : conjugation really sexual; systematic review of phe- 
nomena (Maupas, E.). 
8 chizo genes parasiticus, n. g. (Moniez, R.). Reproduction by fissures in 
homogeneous protoplasm, appearing anywhere, and constricting off inde- 
pendent daughter masses. 
Conjugation of Infusorians (Plate, L). Object : the restoration of 
balance between cyto- and nucleo-idioplasm. Supposition that the idio- 
plasm of cell passes into that of nucleus. Conjugation epidemic, possibly 
due to sudden alteration in external relations. 
In Gregarina fava, n. sp., division of nucleus, formation of asters, 
fusion of conjugating individuals, expulsion of polar elements, formation 
of new nucleus observed (Roboz, Z. v.).
