short account of the principal works on Abyssinian 

 Zoology hitherto published, and some brief observations 

 on the relations and distribution of the Abyssinian 

 fauna. A few species of Vertebrata which appear to 

 have escaped the researches of previous explorers are 

 described and figured. 



In the map compiled by Messrs. Stanford and Co. 

 which accompanies the Geological part, an attempt has 

 been made to represent the physical features of the 

 Abyssinian highlands in a more definite manner than 

 has previously been done, and to distinguish between 

 the great eastern scarp of the plateau and the minor 

 irregularities of its surface.^ 



Although the time spent in Africa by the author 

 was only eight months, the advantages which he 

 enjoyed in consequence of being especially deputed by 

 the Indian Government enabled him to make a con- 

 siderable series of observations in both the branches of 

 science to which his attention was directed, and to 

 obtain a valuable collection, comprising more than 1,600 

 specimens of Vertebrata alone, representing about 360 

 ■species, besides MoUusca, and a few Articulata. 



The time which has elapsed since his return from 

 Abyssinia to India in September 1868, has been prin-

 a great measure by his aid.
