I agree with Gary's interpretation of this case, exactly as stated 
above. While the Code does not operate on precedent, a recent case 
involving two family names "Dasypodidae" ended up being resolved by 
taking the junior name and declaring the entire genus name to be the 
"stem", so the genus Dasypoda is now the type genus of the family 
Dasypodaidae (the other genus was Dasypus). A similar approach in 
this case would lead the mollusc family to become Chilodontaidae. 
That might be the least disruptive approach.

It will require some interested parties to take time to carefully 
document the history of the usage of both names, and prepare a formal 
submission to the ICZN, but it's necessary. Gary's already done a 
fair bit of the crucial stuff above. ;-)
