PROTOZOA. 
Protozoa are classified by Cattaneo (suj^rd), as follows; — 
Lower Monera {Bacteria) = Autoplastidules. 
Upper and Lower Rhizopoda = Protoplastidules. 
Upper Rhizopoda and Infusoria — Autoplastidules. 
Compound Rhizopoda = Symplastidules. 
Maggi (3) enumerates Hackel’s various classifioations ol: the Protista^ 
and, after discussing different views as to relations of Gregarinidce^ &c., 
proposes the following classification : — 
Type I. Plastidular Protista. 
Class I. Bacteria. 
„ II. Cytodular Protista. 
Class I. Monera {Lohomoner a and Rhizomonera, Hackel). 
,, II. Fungi. 
„ III. Unicellular Protista. 
Class I. Flagellata. Class vii. Heliozoa. 
„ II. Lohosa {=■ Anaxhina). Vlii. i?ac?/oZaria (J. Muller). 
,, III. Diatomcce. „ ix. Ciliata. 
„ IV. Myxomycetes. ,, x. AcinetiB. 
„ V. Gregarince. ,, xi. Lahyrinthulece. 
„ VI. Thalamophora (Hertwig). „ xii. Catallacta.

Continues the systematic description of the genera and species com- 
menced in 1880, concluding the Flagellata^ and describing a large pro- 
portion of the Ciliata. To the account of the former group, is added an 
appendix, further enforcing the claims of the Myxomycetes to a place in 
the Animal Kingdom.
