This concerns the rotifers attributed to Ehrenberg (1832), Abhandlungen der Akademie der Wissenschaften, Berlin (für 1831).
A dozen of these names also appear in the earlier paper Ehrenberg (1830), Organisation, Systematik, und geographisches Verhältnis der Infusionsthierchen, mostly marked as new species without any descriptions. I found them on the following pages:
aculeata, Philodina - p. 69
bicarinata, Salpina - p. 85, 90
citrina, Philodina - p. 69
dilatata, Euchlanis - p. 96
lunaris, Monostyla - p. 84, 90; combined with Lepadella in 1832
ornata, Floscularia - p. 65
triptera, Lepadella - p. 83; combined with Metopidia p. 92
gibba, Hydatina - p. 66
laticauda, Hydatina - p. 83, 90
leptocerca, Hydatina - p. 83, 90
terminalis, Hydatina - p. 83, 90
There is also Megalotrocha alba on p. 65. I have checked both papers and could not see any difference in use between these names, and ones that the List of Available Names does attribute to Ehrenberg, 1830. Since both appear together in Abhandl. d. Akad. in 1832, maybe they have been confused?
