Actually, given that living Coelacanths are generally now regarded as
belonging to the clade that includes tetrapods (e.g., Nelson 1994), maybe it
would be better to talk about whether to include "those terrestrial fishes".

To an evolutionary biologist -- perhaps. To the vast majority of other
biologists ot there -- maybe not.

I also agree, but my message was talking about the history-rich Linanean
nomenclatural system, rather than common names.

Does this mean that you also support the un-ranked Phylocode approach?
P.S. Although it may seem that I am a lobbyist for Phylocode, I actually
seriously doubt that I will ever use it in my own work.
