Several of the Ethiopian Mammalia are sedentary forms, and 

 seem to point to an earlier settlement than across the recent deserts. 

 There is no trace of any immigration from the Indian region. Of 

 the peculiar species, Hyrax syriacus belongs to an exclusively Ethio- 

 pian and isolated type, yet is specifically diiferent from its congeners, 

 which are all most sedentary in their habits. 



The Avifauna is very rich in number of species, most unequally 

 distributed. The Ethiopian and Indian types are almost exclusively 

 confined to the Dead-Sea basin, excepting only the desert forms. 

 Tliere are several Indian species, as Ketupa ceylonensisy which have 

 no aftinities with any Ethiopian forms. Of the peculiar species, 

 besides several modifications of well-known Paleearctic forms, there 

 are eleven, belonging to as many different Ethiopian and Indian 

 genera. Three of these are decidedly Indian in their aflfinities. The 

 Avifauna of the Dead- Sea basin is decidedly distinct and typical, 

 sometimes Indian, more generally Ethiopian in its character. 



In the Reptilia there is a less prominent intrusion of Ethiopian 

 types, there being a general similarity to the Egyptian herpetological 

 fauna, which must be classed within the Palsearctic region. The 

 Indian is present in Daboia xanthina ; and the affinities of a new 

 genus Rhynchocalamus are rather obscure. Snakes in particular 

 are more limited to the original locality of the individuals j and the 

 groups, like the individuals, are more stationary. 



The fluviatile ichthyological fauna is much more distinct, though 

 the number of species is small. In its consideration we confine 

 ourselves to the Jordan and its tributaries, in which are three 

 Nilotic fishes, three others extending eastward in Asia, six to other 

 rivers of Syria, and four peculiar, bearing a strong affinity to the 

 species and genera (as Chromis and Hemichromis) of tropical Eastern 

 Africa. 



Of the Mollusca, most of the peculiar species have no geographical 

 signification. The Pulmonifera have developed in groups which
