Abstract
A discovery of importance to the geology of the Mandated Territory of New Guinea, and especially as far as the Tertiary foraminifera-bearing rocks are concerned, was recently made by N. H. Fisher, Esq., M.Sc., Government Geologist of New Guinea. During a short stay at the Chimbu aerodrome, whilst the aeroplane was being unloaded, Mr. Fisher collected specimens of a limestone from a small creek near the aerodrome, which is in the Wahgi River area, New Guinea. In a communication to the writer, he stated that these limestones form steep escarpments along the Bismarck Range on the northern side of the Wahgi Valley. The elevation of the locality is 5,100 feet above sea level. When a microscopic study of thin sections of this limestone, which was sent to Canberra for examination, was carried out, it was found that the rock contained two foraminiferal genera that had not been previously recorded from the Mandated Territory. These genera were Lacazina and Biplanispira. Lacazina has been recorded by Dutch geologists from the Eocene of Dutch New Guinea but Biplanispira, as far as is known, has previously been determined only from the Eocene of Borneo.
