The Moluccan cuscus (Phalanger ornatus) was collected by Wallace on Bacan Island, Indonesia and named by Gray in 1860. Wallace writes the following about this species in his book The Malay Archipelago: "The figure represents Cuscus ornatus, a new species discovered by me in Batchian, and which also inhabits Ternate. It is peculiar to the Moluccas, while the two other species which inhabit Ceram are found also in New Guinea and Waigiou." This illustration is from Wallace's book The Malay Archipelago.
