Adult male. General colour above and below dusky black, the 

 gloss having somewhat of a grepsh brown shade, the back and wings 

 glossed with purple, as also the under surface ; the quills externally 

 dull greenish black ; " bill, legs, and toes dark horn-colour ; irides 

 dark brovm " {Andersson). Total length 18 inches, culmen 2"5, 

 wing 13-8, tail 7'7, tarsus 2-7. 



Young. Dusky brown where the adult is glossy black, nearly all 

 the gloss being absent in the young ; the wings and tail as in the 

 adult ; bill horn-coloured at tip. 



Ohs. Professor Schlegel (M. P.-B. Coraces, p. 27) refers to a 

 species which he names " Corvus minor, Heugl.," and which, he 

 says, resembles in every respect C. capensis, notably in the form of 

 the beak, feathers, and in its colours, but is very much smaller. 

 The only example in the Leiden Museum was purchased of Verreaux, 

 in 1858, but without an exact locality attached to it; and Dr. von 

 Heuglin (Orn. N. O.-Afr. p. 500) doubts whether it is the same 

 species to which he assigned the name of C. minor in 1856. The 

 only differences between G. minor and true C. capensis consist in 

 the large size of the latter ; and this is not sufficiently marked to 

 enable me to separate them, as will be seen by the following mea- 

 surements, which, indeed, show a preponderance in size in favour of 

 the bird from North-eastern Africa.

It will be seen from the above that it is impossible to separate 

 the Abyssinian species on the score of larger dimensions ; and there- 

 fore Professor Schlogel's C. minor still requires identification. 



Hab. (South and North-east Africa.
