REPRODUCTION. 
Prot. 35 
1. Asexual: fission, schizogony, etc. 
Schizogony in Adelea transita n. sp., L^ger (189). — Schizogony of 
Klossiella described and compared with that of Caryotropha mesnilii , 
Woodcock (363). 
Schizogony of : Hcemogregarinabiretorta , Nicolle (249) ; H. mauritanica 
n. sp., 8 merozoites being formed, Sergent (314). 
Meronts and rnerogony in Thelohania legeri , Hesse (141). — Schizogonous 
multiplication in T. moenadis n. sp., Perez (263). 
Asexual multiplication (binary fission and multiple rosette-formation) 
in fferpetomonas muscce-domesticce , Prowazek (277). — Multiplication by 
longitudinal fission of II. subulata , L£ger (186). — Proceess of division 
described: in Joenia, annectens , Grassi & Foa (126); in Trichonympha 
agilis , Foa (110). — Multiplication of Trypanosoma granulosum by unequal 
division, Sabraz^s & Muratet (295). 
Fission in Anophrys echini n. sp., Di Mauro (231). — Division in Disco- 
phrya and Opalina intestinalis , Cohn (77). 
2. Sexual: gametes and conjugation. 
On the general significance of conjugation, Calkins (56). — Notes on 
conjugation (“exogamy”) in certain Protozoa, Hartog (136). 
“ Association ” and conjugation in Difflugia urceolata , Zulzer (369). — 
Evidences pointing to sexual ( Pelomyxa -) forms in the life-history of 
Amoeba proteus , Calkins (57). 
Formation of gametes (sporoblasts) in Gregarina ovata , Paehler (256). 
— Markedly anisogamous conjugation in Stylorhynchus ; certain very motile, 
spermatozoon-like, male elements are sterile and have acquired a sub- 
sidiary function, LIsger (188). 
Two types of form (micro- and megagam etocytes ?) and multiplication 
(micro- and megagamete-formation ?) in Joyeuxella, Brasil (41). [These 
two types of multiplication seem to the Recorder to possess a certain 
agreement with what occurs in Schaudinnella (Nusbaum, Zool. Rec. 1903 
[282]) and suggest that the affinities of J. may be sought in that direction.] 
Micro- and megagametocytes in Adelea transita , LIsger (189); (associa- 
tion observed but not actual gamete-formation). — Micro- and megagameto- 
cytes and microgametes of Angeiocystis , a new Coccidian, described, 
Brasil (40). 
Distinction of male and female forms (gametocytes) in “ Leucocytozoon” 
danilewsJcyi, Berestneff (18). 
Important account of the sexual process in certain parasitic Flagellates ; 
autogamy (or self-fertilization) in Trichomastix , and heterogamy (true sexual 
conjugation) as well as autogamy in Bodo ; comparison with the heterogamy 
of Trichomonas , Prowazek (278). — Sexual processes (fertilization, “ etheo- 
genesis ” or male autogamy, and parthenogenesis) in Herpetomonas muscce- 
domesticce, id. (277). 
True conjugation in Trypanosoma noctuce and Spirochceta ziemanni , 
taking place in the gnat, described, Schaudinn (301). 
Note on conjugation in Dileptus gigas , Hertwg (139). — Conjugation in 
Paramcecium bursaria described, Hamburger (134). 
3. Nuclear division : directive centres, etc. 
Description of nuclear division in Amoeba proteus , Averintzev (7). —

condition in Amoeba proteus, Calkins (57).— Behaviour of the nuclei and

“ maturation ’’-process, Paehler (256). — Nuclear changes and multipli- 
cation during sexual reproduction in Stylorhynchus ; the nuclei are dis-
