Clutch size information required

[PilbaraPythons]

I am looking for information on maximum clutch sizes known of commonly kept snake species.
For example, it is written in a one book that Acanthophis pyrrhus has up to 12 young yet I know of one that gave birth to 21 a few weeks ago.
This is the sort of information I need if people out there can please help.

Cheers Dave
