MAX WEBER (1908, Nova Guinea, 5 (2): 264) referred 6 specimens of a globe-fish, collected by Dr. KOCH in the mouth of the Merauke River, New Guinea, to Tetrodon staigeri DE CASTELNAU. These specimens are in the Amsterdam Museum which later on received some more and still larger specimens from the same locality. Re-examination of these specimens showed me that they cannot be referred to T. staigeri, which is said to be near T. hispidus, and hence, according to the classification of FRASER-BRUNNER (1943, Ann. Mag. Nat. Hist. (11) 10: 1), belongs to the family Tetraodontidae, wherefes the Merauke specimens without doubt belong to the Lagocephalidae. It turned out that they belong to a new species,
