Monster sources

[cildarith]

Archer Bush (D&D module B3 Palace of the Silver Princess)
Death Watch Beetle (AD&D first edition Monster Manual II)
Crypt Thing – (AD&D first edition Fiend Folio)

As far as I know, these are all correct.

The crypt thing is definitely in the 1st edn Fiend Folio. I guess that's its earliest incarnation.
