THE collection of which the following is a systeniatic account was made by Prof. R. H. Compton in New Cdetlonia and the Isle of‘ Pines dnriiig 1914, with the aid of grants from tlie Royal Society, tlie Percy Sliicleii Trust Fund, and tlie Worts ’l’ravelling Fund of (‘ninbridge Universi tp. C’ollecting materials were also provided by tlie Cnmbridge Botaiiy School and tlic British Museum, Natural History. The sliecimens collected have been prescnted to the British Museum, where the greater part liave been determined. Prof. Coinpton liopes Inter to publish a paper or papei*s dealing with the New Cldedonian vegetation froin the slandlioints of Ecology and Geographical Distrihtion. A considerable quantity of materid WIS pre- served in a condi tion buitable for iriorphological and nnatomical research, and several papers are f‘orcshaclowccl on these aspects of sonie of the interesting forms in wliicli tile Flora of New Caleclonin is 50 extraordinarily rich. A general account, including a description of the geology, topograpliy, and clininte of the Islnnds 11ns been co~nniunicateclhy Prof. Compton to the Royal Geographical Society *.
