which differs from the Pelomym of the fresh- water by its filiform and 
reticulate pseudopodia, and by the absence of vacuole?. 
Wallengren (204) has studied the ciliate Infusorium Licnophora , and 
arrives at the result that it is not an intermediate form between 
hypotrichous and peritrichous Infusoria . The keotropism of Licnophora 
is the result of a shifting of the originally dexiotrop zone. 
Zacijarias (272), in a paper on the structure of the monads and 
colonies of Uroglena volvox } Elirb., confirms in general Ehrenberg and 
Saville Kent’s views, that the monads are joined together at their inner 
ends by a system of dichotomously branching threads. 
2. Embryology. 
13 argon I (10) describes the reproduction of the Foraminifer Salpicqlfl 
amylacea , n. g. & sp, 
Brauer (25) gives an exhaustive account of the encystation of 
Actinosphcerium eichhorni. 
Cattle & Millar (36) describe the development of Coccidium 
oviform e. 
Coronado (49) : reproduction of Ilcematozoa. 
Isijikawa (111) has investigated the division and spore-formation of 
Noctiluca miliaris , and describes the formation of archoplasm, chromo- 
somes and spindle-fibres. , ; ... 
Johnson (115) describes the Plastogamy of Actinosphcerium , charac- 
terized by the fusion of the plasma only, not by that of the nuclei. 
After coalescence, a more rapid division could be observed within a day 
or two. L 
Podwyssozky (188) describes the development of Coccidium oviforme 
in the bile-ducts of Rabbit. 
Buffer & Plimmer (214) : mode of reproduction of cancer parasites. 
Ryder (216) has noticed two new methods of reproduction in Euglena 
viridiSf under the abnormal condition of being constrained principally 
to two dimensions of space. 
Schaudinn (227), in a paper on the nuclear division, with subsequent 
cell-division of Amceha crystalligera , Gruber, has been able to confirm the 
observations made by F. E. Schultze on A. polypodia. 
Stiles (250) gives an account of the life-history of IJolophryq (— 
Ichthyophthirius ) multijilis , Biitschli, parasitic on Fishes, aod of experi- 
ments to remove this parasite. 
3. Physiology and Biology. 
Celli & Fiocca (41) describe successful experiments in the cultivation 
of Amceha and the two phases, the amoeboid and the cystic, which all 
Ammbic seem to exhibit.
