[Taxacom] Family Chilodontidae - unresolved homonym inCharaciformes and Gastropoda?

my understanding (without having the time just now to check) is this:

Chilodontidae Eigenmann, 1912 [emend. Fowler 1950]
=Chilodidae Eigenmann, 1912 [incorrect original spelling]

So, does that mean the fish family name dates from 1912 or from 1950 for nomenclatural priority purposes? Or, does it mean that Chilodidae is a useable name for the fishes but Chilodontidae is not, and therefore requires replacing unless the subject of a ruling by ICZN?

The mollusk name is based on Chilodonta Etallon, 1862, not Chilodon Ehrenberg, 1831. It was named as Chilodontinae Wenz, 1938. The fish family was named as Chilodinae Eigenmann, 1912 (Memoirs of the Carnegie Museum 5: 271, http://www.biodiversitylibrary.org/item/32845#305. It was emended to Chilodontidae by Fowler 1950, Arquivos de Zoologia 6: 214.

There was a protist family Chilodontidae, used as early as 1876, but apparently abandoned, perhaps because Chilodon Ehrenberg, 1834 was preoccupied by Ehrenberg, 1831. The protist Chilodon replaced by Chilodonella, which is currently(?) placed in Chlamydodontidae.

The next available name for the mollusk family is Cataeginae McLean & Quinn, 1987, but it refers to a different subfamily. No other name is available for the nominotypical subfamily. The best course might be to use Chilodidae for the fish family. Chilodinae and Chilodidae have about 20% of the usage (they combine for 89 hits in Google books, compared to 326 for Chilodontidae or Chilodontinae minus Wenz or Trochidae (a family related to Chilodontidae).

It took a long time before the mollusc name (Chilodon) was given a
family rank, then, since it dates to 1831. The fish name Chilodus
dates to 1844, and I'd be utterly amazed if it was never used at
family rank prior to 1938. Definitely sounds like something for the
Commission, and I expect the mollusc name will need to be altered.
