[BUG] [4.2] Inconsistent plural of "hydra"

[Pussy Galore]

I hope this is the right place, and the right way, to report a bug.

While playing 4.2 I noticed that the plural of "hydra" is inconsistent. A hydra summoning its kin will produce messages such as this:

The 9-headed hydra summons hydrae.

Whereas the monster list ('[') will show e.g. this:

You are aware of 11 other monsters:
M 3 9-headed hydras
...

The monster description for the 9-headed hydra also has "[...] and may cast spells intelligently which [...] summon hydras".

Just a cosmetic issue, but worth changing for the next release.

i think this merits enough reason for a change.

Always good to be consistent with these things
