Among butterflies we have Ahantis, one of the Ilesperidie,from Mozambique; and in Coleoptera, 2 genera of Cicindelidae,8 of Carabida3, 1 or 2 of Cefconiidtc, and about half-a-dozen ofLongicorns: a mere nothing, as we shall see, compared with thehosts of peculiar genera that characterise each of the other sub-regions. Neither do laud-shells appear to present any peculiarforms. • The fact that so very few special types characterise the exten-sive area now under consideration is very noteworthy.

In none of the other great tropicalregions does it occur, that the largest portion of their area,although swarming with life, yet possesses hardly any distinctivefeatures except the absence of numerous types characteristic ofthe other sub-regions. Plate IV.—Ilhistrating the Zoology of East Africa.—Althoughthis sub-region has so little speciality, it is that which aboundsmost in large animals, and is, perhaps, the best representative ofAfrica as regards zoology. Some of the most distinctive of Africananimals range over the whole of it, and as, from recent explora-tions, many parts of this w^ide a
