A rare work by Christian Gottfried Ehrenberg (1795-1876), the founder of protozoology and microbiology. Nissen only quotes this second volume. This work is of fundamental importance to the knowledge of Protozoa. Many new species are described and the hand-coloured plates are of very high scientific quality. Large paper copy. The plates are shorter than the text pages. Boards rubbed; old repair to title page lower margin, vague dampstain to the last text leaves, plates rather toned. A good copy. Nissen ZBI, 1249. Not in Cat. BM(NH).
