Molluscan taxa and nomina nuda in the Journal des Museum Godeffroy (JMG)
The majority of new molluscan taxa were introduced by Bergh in a four-part series on the nudibranchs of the South
Sea. It must be noted that Bergh kept listing his taxa as “n. sp.” often long after they had been formally described in
these and other publications. An additional complication is caused by the fact that Bergh near-simultaneously
published on the same taxa in another complex multi-year publication series edited by Carl Gottfried Semper
(1867–1916) as “Reisen im Archipel der Philippinen”; Bergh’s series therein was likewise called “Malacologische
Untersuchungen” (e.g., Bergh 1870–1878). His cross references among these and other contemporary publications
were not always correct, and priority issues are at times difficult to disentangle. As will be shown below, the first
three parts of Bergh’s nudibranch treatment in the Journal were published in 1873, 1874, and 1875, respectively.
He expected the fourth part, with a treatment of Chromodoris, to appear in 1876 and often referred to that work as
if it were already published in his other works of that time (e.g., 1876; 1877a). However, publication of that
frequently referenced article was delayed until JMG Heft 14, in 1879.
For example, Bergh (1879a: 3) considered Goniodoris picturata Mörch, 1863 preoccupied by Pterodoris
picturata Ehrenberg, 1831 and introduced a replacement name, Chromodoris moerchii [as mörchii] for it.
However, Bergh had taken this step previously in the Jahrbücher (1877a: 56). In that article, he referred to his
“earlier” action in this matter, stated to be in the “Journ. d. Mus. Godeffroy. Heft XII. 1877” (the issue that
ultimately appeared in Heft XIV in 1879). The list of molluscan taxa introduced in the Journal (see below)
investigates such priority issues.
