Mammalia. — The only forms of Mammalia peculiar to this 

 sub-region are Tluropithecus, one of the Cynopithecidae confined 

 to Abyssinia ; Petrodromus and Ehyncliocyon, belonging to the 

 insectivorous Macroscelididae, have only been found in Mozam- 

 bique ; the Antelopine genus Ncotragus, from Abyssinia south- 

 ward ; Saccostovins and Pelomys genera of Muridce inhabiting 

 Mozambique ; HeUroccpliahis from Ab3^ssinia, and Hcliophohius 

 from Mozambique, belonging to the Spalacidse ; and Pectinator 

 from Abyssinia, belonging to the Octodontidfe. Cynocephalus, 

 Rhinoceros, Camelopardalis, and antelopes of the genera Oryx, 

 Cervicapra, Kohus, Nanotragus, Cephalophus, Hippotragus, Alce- 

 phalus, and Catohkpas, are characteristic ; as well as Felis, 

 Hymna, and numerous civets and ichneumons. 



Birds. — Peculiar forms of birds ai'e hardly to be found here ; 

 we only meet with two — Hypocolius, a genus of shrikes in Abys- 

 sinia ; and Balmniceps, the great boat-billed heron of the Upper 

 Nile. Yet throughout the country birds are abundant, and most 

 of the typical Ethiopian forms are well represented. 



Reptiles. — Of reptiles, the only peculiar forms recorded are 

 Xenocalamvs, a genus of snakes, belonging to the Calamariidae ; 

 and Pythonodipsas, one of the Dipsadidte, both from the Zambesi ; 

 and among lizards, Pisfurus, one of the Geckotidae, from Abys- 

 sinia. 



Amphibia and Fishes. — There are no peculiar forms of amphibia 

 or of fresh-water tishes. 



Lisec's. — Insects are almost equally unproductive of peculiar 

 furms. Among butterflies we have Ahantis, one of the Hesperidae, 

 from Mozambique ; and in Coleoptera, 2 genera of CicindelidiP, 

 8 of Carabidiie, 1 or 2 of Cetoniidse, and about half-a-dozen of 

 Longicorns : a mere nothing, as we shall see, compared with the 

 hosts of peculiar genera that characterise each of the other sub- 

 regions. Neither do land-shells appear to present any peculiar 

 forms. 



The fact that so very few special types characterise the exten- 

 sive area now under consideration is very noteworthy. It justifies 

 us in uniting this large and widespread tract of country as 

 forining essentially but one sub-division of the great Ethiopian
