Remarks.

The "Africanische Gesellschaft", or formally "Deutsche Gesellschaft zur Erforschung Aequatorial-Africas", sponsored the “Loango-Expedition” from 1873-1876 under the leadership of the German geographer and explorer Richard Paul Wilhelm Güssfeldt. The expedition had the task to establish a station at the Loango coast (at Chinchoxo), which was to serve as a depot for the material collected during the expedition. Geographic-topographical explorations into the interior of the African continent were also intended to be carried out. With an interdisciplinary research team, comprising the medical officer and zoologist Julius Falkenstein, the geographer Eduard Pechuël-Loesche, the geodesist von Görschen, Reserve Lieutenant Hans von Hattorf, the mechanic Otto Lindner, the botanist Herman Soyaux, and the topographer Major Alexander von Mechow, Güssfeld travelled for two years, starting in July 1873. They mainly followed the coastal area of Cabinda, on the Kouilo river, the Chiluango river, and on the lower course of the Nyanga river. From March 1874, they turned to Luanda, on the Cuango to Dondo and to the rapids of Cambambe, as well as to Quicombo and Novo Redondo ( Güssfeldt et al. 1879, Weidmann 1894, Heintze 2007, Marques et al. 2018). The amphibians and reptiles collected during these trips were sent to ZMB and described by Peters (1877a, b).
