I've compiled a list of all the Pathfinder Monsters released under the 3.5 rules that have yet to make the jump to PRPG rules.
It would be great to continue seeing these monsters updated in future Bestiaries and I suspect we will.

The following are Unique Monsters and not likely to be seen in a Bestiary.
Prince in Chains
Achaekek, the Mantis God
Lawgiver
yethazmari
night monarch
Ahriman
Xotani
Sunlord Thalachos
Menotherian
Thais
*Note
Achaekek and Ahriman are not likely to be given stats again until rules are made for Epic play. Even then these two being a God and Demigod are not likely to be given stats simply because Paizo frowns on Stating up deities.
The following two monsters were only given stats with special permission. They can not be reprinted again unless Pazio is again given special permission for them to appear in their products.
deep crow
coeurl
Lastly we have templates.
runeslave
Osirion mummy
nosferatu
black blooded
sea-sworn
necropyre
dark ice creature
wyrmskull
painted creation
Not all of the monsters listed above translate well for addition to a geneal Bestiary. I wouldn't mind seeing a Monsters of the Inner Sea Region 64 page book in the Chronicles line to bring those monsters into the fold.
Good list and I agree, didn't you forget about the Bog Strider tho?
You know I could have sworn I seen stats for the Mantis God somewhere...
From that huge list these are my favorites and I hope to see them in the Bestiary 4 next year.
bonestorm
red reaver
chained spirit
danse macabre
darklands sentinel
swamp barracuda
carrionstorm
unchosen gnoll
emkrah
rukh
miengu
black jinni
skull ripper
mother of oblivion
scanderig (forgefiend)
kuchrima
harridan
rajput ambari
sikari macaque swarm
hadhayosh
Good list and I agree, didn't you forget about the Bog Strider tho?
The Bog Strider's stats are in Pathfinder #32 - Blood for Blood, which is PFRPG, not 3.5.
