Limnocnida rhodesiæ and its Distribution

Abstract

WHILE resident in Johannesburg, South Africa, we often made inquiries regarding the possible occurrence of the interesting medusæ belonging to the genus Limnocnida in the subcontinent, and searched many rivers, dams, ponds and pools for them. On personal visits to various parts of Southern Rhodesia in 1920 and 1927, unfortunately, specimens could not be obtained. However, at Hartebeestpoort Dam, on the Crocodile River, the chief tributary of the Limpopo, about 22 miles from Pretoria, Transvaal, on March 23, 1926, at the end of the summer season, one of us found three medusæ, 18–20 mm. in diameter. These specimens we considered to be Limnocnida rhodesæ, Boulenger.
