**Eulenstein**, Theodor (?-1875)  
**DIATOMACEARUM SPECIES TYPICAE ....**   
Century I, \[edition 1\], numbers 1-100. Stuttgart, 1867. Century I, edition 2, numbers 1-100. Dresden, 1869. Century II, numbers 101-\[?200\]. Dresden, \[?1869\].   
Index information was derived from microscope slide labels and the schedule of taxa printed inside the century box cover (Century I, edition 2).

The Farlow Herbarium has copies of edition 1 and edition 2 of Century I. Both editions have the same inventory of taxa associated with each numbered slide, but with respect to localities slide numbers 27 and 49 differ in the two editions. All references to this Eulenstein set in this index are to edition 1, unless edition 2 is explicitly indicated. Information from edition 2 has been entered solely when it differs from that in edition 1.

I have not seen a complete set of the second century (no. 101-\[200?\]). The Farlow Herbarium has 23 slides for this century: 103, 104, 109, 112, 115, 118, 119, 129, 132, 134, 136, 137, 141, 145, 146, 148, 151, 156, 159, 164, 178, 180 and 198. I have seen in the Febiger Collection at the Academy of Natural Sciences of Philadelphia six other numbers from this century and included them in this index: 106, 108, 116, 149, 150, and 176. The second-century slides bear a coverglass rimmed with a circular metal ring bearing the impression "Th. Eulenstein / Dresden / Gold Medaille / St. Petersburg 1869."
