Also given the history of Europeans and animals on islands, the faunal range would probably be the same as OTL.
Palaeopropithecidae would all be dead, Pygmy hippos would all be dead, the elephant birds would all be dead as would all ground egg laying species.
Rats, dogs and hunting/collecting pressures would insure only the swiftest or illusive wildlife survived.
One could argue that some could be kept as curios but the lemurs that perished were specialized and in some cases quite large not likely to survive a journey to some preserve by sea.
You may on the other hand have a perserve where visitors could look at them like curios but you know the fauna doesn't change much in terms of colony profitability.
