Well I thought to myself I wouldn't add to this list, but now seeing it as just a bit of fun thought I would give it a shot
Madagascan carnivores - hopefully some will find their way into Islands. I just find species like fossa, narrow-striped mongoose and the like really fascinating.
Some small cats - maygay, ocelot, golden cat, fishing cats are some of my faves, but would love to see any
Binturongs
Some unusual hoofstock, maybe Impala, gerenuk, a gazelle species, wildebeest, a caprid species.
I know AG would like caracals and more gibbons
Thats about it for mammals. Will maybe think of some birds and herps later (I'm sure somebody would agree black caiman would be good

)
