SOTTERA—FJUXA OF SEXAFE. 43 



The sandstone below the trachyte on the hill east of 

 Senafe, and that on the other hiU to the south, may 

 possibly be distinct from the massive Adigrat sandstone, 

 but there is no difi'erence in mineral character of any 

 importance. Beneath Senafe rocks no sandstone can be 

 ti"aced, just as beneath Akilb Teriki. Kishyat appears 

 to rest on sandstone. 



The great mass of Sowera requires no special descrip- 

 tion. It consists of rather coarse sandstone, white in 

 colour, with brown ferruginous bands here and there. 

 Other similar great plateaux to the westward correspond 

 with it — that of Tsaro, between the Komayli raviae and 

 that of the Haddas, and the southern portion of the 

 Halai plateau west of the Haddas. AU of these consist 

 of massive horizontal beds of sandstone, and are bounded 

 by huge precipices. They are, in fact, great flat-topped 

 spurs, projecting from the mass of the table-land, and 

 separating the different valleys. 



The fauna of the neighbourhood of Senafe is quite 

 different from that in the pass below, and is fairly typical 

 of that inhabitiag the temperate regions of Abyssinia. 

 Some of the mammals, however, as the hamadryas 

 monkey, the spotted hyaena, and the wart-hog,^ are 

 identical with those found on the sea-coast ; others, as 

 the hyrax {H. JBrucei), the ichneumon {Herpestes raut- 

 gigella), the klipspringer, and koodoo, extend into the 

 sub-tropical region, whilst a few appear pectdiar to the 

 highlands proper. Amongst these, the principal are the 



' As I did not shoot this myself, nor see it close enough to be quite sure 

 of its idcntitT. I am not certain of the animal being the snme.
