I found 1.
Ekolid, Fiendish Codex 1 p38, 6HD, outsider
FWIW, I also found
Beguiler (not the class), Shining South p60, 1HD, magical beast
Deep Dragon, Drow of the Underdark p114, the wyrmling only has 6 HD, dragon
The last 2 aren't outsiders or elementals, but this board has a way of making things work that shouldn't.
