Remarks.

Depicted in Tornier (1896, pl. 4, fig. 20), reproduced in Ahl (1931b: 377, fig. 252). From April 1890 to July 1892, Stuhlmann accompanied Mehmed Emin Pasha’s [actually Eduard Karl Oskar Theodor Schnitzer] expedition to the East African lake region as a zoologist. This took him as far as the northeastern part of today’s Democratic Republic of the Congo ( Stuhlmann 1894). Today, his extensive zoological collections are mainly housed at ZMB and in the Zoologisches Museum der Universität Hamburg. The German physician, explorer and hunter Dr. Berger travelled to areas of British East Africa, Uganda, from July 1908 to 1909. He visited the border area with Democratic Republic of the Congo and Sudan, and returned to Germany via Egypt ( Berger 1924, 1942). A large part of the zoological objects he collected is at ZMB.
