Dr. Ph. H. Kuenen kindly entrusted me with a suite of corals collected by him on the island Flores during his cruise with the Expedition on board of H.M. „Willebrord Snellius”. The exact locality is North coast near Papang where the road Papang-Rioeng-Rawoe forkes, 550 m above sea level. Nine different species were collected. Among these is one new species, Fungophyllia millepunctata. Of one coral, a Porites, the species could not be identified with certainty, though it strongly resembles a Porites species from the Miocene Progo-beds of Java. From the other 7 corals the following data on their stratigraphical distribution are known.
