The present paper deals with the anatomy of the reproductive system 
and the externals of a new Phreodrilid genus taken on the Stellenbosch 
Mountains during September, 1910. 
This constitutes the first record of any representative of the family in 
Africa ; but at the same time the occurrence is not surprising, but rather 
expected, since representatives are found in all the other land masses of 
the Southern Hemisphere, including Kerguelen Island, which lie south of 
the parallel 30° S. We refer later to the significance of this distribution. 
Several other essays during different times of the year both on the 
Stellenbosch Mountains and Table Mountain had proved fruitless in 
discovering either the same or different forms, since the first success ; and 
this was explained tentatively by us in a paper recently read before the 
South African Association for the Advancement of Science as being prob- 
ably due to the fact that the worms mature during the spring and that 
they disappear from the pools during the hotter months of the year. 
This explanation has been verified by the discovery of large numbers 
of another representative on Table Mountain during the past week. 
Preliminarily we may note that the circumpolar distribution of the 
family is now complete, and we do not hesitate to remark that a detailed 
survey of the mountains above 3,000 feet and flanking the southern limits 
of the Karroo will furnish still many representatives of the family. 
Not only does the new genus described herein prove interesting 
zoogeographically, but also is of important phylogenetic interest in 
explaining the spermathecal and male reproductive apparatus of such 
forms as Phreodriloides described by Benham from Mt. Koscisuko, New 
South Wales, and of a form described by one of us (E. J. G.) from Mt.
