[Beceived January 6, 1899.] (Plates XL & XII.) When I had the honour of reading the first part of this paper before this Society, nearly a year ago, I could not have foreseen the enormous additions to our knowledge of the genera and species of African Cichlidce Avhich Avere so soon to folloAv through the examination of the collections made in Lake Tanganyika by M r . Moore, and in the Congo by the Officers in the service of the Congo Free State. The Tanganyika forms have been described in the ' Transactions' of this Society (vol. xv. pt. 1,1898), the Congo forms are being published in the ' Annales du Muse'e du Congo.' In the first part I distinguished 9 genera and diagnosed 33 species of the first 6 genera, reserving for the second part the definitions of the species of the genera Tilapia, Docimodus, and Paretroplus. Tbe additions to which I have alluded necessitate an alteration in this plan, and in order to bring m y account up to date I have decided to prepare a neAv synopsis of the genera, amounting now to 19 instead of 9, and to enumerate all the species of the genera previously dealt with by me, with a mere reference to the first part or to the ' Transactions' paper in which the Tanganyika forms have been described and figured. 1 Cf.
