Excerpt from The Danish Ingolf-Expedition, Vol. 3: Part 3; Crustacea Malacostraca (II.)

In order to arrive at a fair idea of our knowledge of genera and species established before the middle of 1912 I have inspected the Zoological Records since 1877 and besides looked over the vast majority of the papers. I have attempted to count the genera and species hitherto established excluding of course the synonyms, but it was impossible to arrive at absolute certainty as to the number of species, because in a few cases it cannot be made out whether a species is valid or ought to be cancelled as a synonym, and some few species have been so poorly described that they can scarcely be recognized with any certainty. But I am sure that the following numbers are nearly correct.
