This paper deals with a collection of Arachnida and Myriopoda which has been entrusted to me by Dr V. FitzSimons, Director of the Transvaal Museum. The Myriopoda consist mainly of a general collection which has accumulated over a number of years in the Museum from various provinces of the Union, and more recently, as the result of Museum expeditions to the Kalahari, South-West Africa and southern Angola. The Arachnida, consisting of Scorpions and Solifugae, are more exclusively from South-West Africa and southern Angola, a region which has always provided interesting forms in these orders. I have also been allowed to include some records and notes on Transvaal and South Rhodesian species of Solifugae. Keywords: Arachnida, Myriopoda, New species, Scorpions, Solifugae and Sun spiders.
