Extract

The collection of echinoids, which is the subject of this report, was made by Mr R. A. Farquharson, M.A., M.Sc., F.G.S., Government Geologist, during his survey of British Somaliland in the year 1923–24. The collection was presented by the Colonial Office to the Geological Department of the British Museum, and the Keeper, Dr F. A. Bather, F.R.S., has been good enough to allow me to examine and describe these interesting specimens. I have been fortunate in having beside me for comparison the echinoids from Somaliland in the Hunterian Museum, which were collected by Mr B. K. N. Wyllie, B.Sc., F.G.S., and Dr W. E. Smellie, and through them presented by the Anglo-Persian Oil Company. I take this opportunity of expressing my thanks to Professor Gregory for his interest in the collection and for much kind help.
