Peng-pu

— A large part of the material from the Huai valley was collected on the spot by the Swedish civil engineer, Orvar Karlbeck, who for many years lived at Peng-pu in An-huei, and was handed over by him to some Swedish collections—the Countess Hallwyl's, the East Asiatic Collections, and the author's—but a number of specimens have been scattered in other collections, such as the Freer Gallery in Washington and the Hopp Museum in Budapest.
