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.

Paperback. Zustand: New. Print on Demand. This book catalogues the results of 20th century Danish expeditions to the marine environment surrounding Greenland, Iceland, and the Faroe Islands. The author's investigations during the first Ingolf expedition led to a new approach to collecting deep-sea invertebrates, vastly increasing the number of specimens and species available for research. Many of the specimens gathered were entirely new to science. The book's main focus is the 78 species of Tanaidacea discovered and described by the author. Before the expeditions, only nine species were identified in the region. Tanaidacea are small crustaceans, most species ranging from 3 to 4 millimeters in length. Their habitat varies from the shallows to depths exceeding 700 meters, but the majority are found below 300 meters. This book represents an exhaustive work in the field and provides a greatly expanded understanding of the deep-sea fauna and the diversity of Tanaidacea in the North Atlantic.
