The locality of the specimen which is the subject of the present note is Namaqualand, South Africa. It was brought over from Africa, together with other minerals, about the year 1861, by Mr. Edgar Layard, who was at that time acting as curator of the Museum at Cape Town. It was in the same year that Mr. Layard presented to the British Museum Collection specimens of Namaqualite, the mineral which was subsequently examined by Professor Church and shown to be a new species. The connellite was given by Mr. Layard, among other specimens, to Mr. T. Davies, who in 1887 presented it to the Museum. It was not recognised as certainly connellite, but was put aside for chemical examination as being either clinoclase or connellite.
