Show 1894.] EISHES FROM E. AERICA. 85 these will be fully explained in his forthcoming itinerary of his expedition1. Besides, he discovered two new forms, one of the polytypic genus Agama, and the other a singular new genus of Geckoids. Several of the species had been previously known from one or two other localities only: the Egyptian Dipsas obtusa has been discovered by him to extend southwards to the Equator, and the West-African Hemidactylus brookii proves to be one of those which extend right across the Continent. This is also the case with Dermophis thomensis, one of the seven Batrachians collected by Dr. Gregory. So far as we know at present, some of the genera of Pishes inhabiting Tropical Africa, like Chromis and Barbus, preponderate over the others as regards the number of species. Not only are the various fresh waters inhabited by distinct local forms of the genera mentioned, but almost every piece of fresh water harbours several species of the same genus. Six out of the thirteen species of which specimens have been collected by Dr. Gregory are new, and m y examination of them has been greatly facilitated by the large size of the specimens and the excellent state of their preservation.
