CORVUS UMBRINUS '23 



and Marocco this species does not appear to have been recorded so 

 far, but it may possibly occur in some of the southern districts of 

 both those countries. In Tripoli I think there can be no doubt that 

 it occurs, though Mr. E. Dodson failed to secure any specimens of 

 it when recently collecting in that country. 



In Tunisia, C umbrinus is apparently to be met with only in the 

 extreme southern districts, but where the species occurs it appears 

 to be fairly common. According to Mr. Aplin and M. Blanc, it 

 is to be foimd near Tatahouine, Metamur, Medenine, Oglet-Ksar, 

 and Djerba, or in fact throughout the greater part of the south 

 coast region of the Eegency, from Gabes down to the Tripoli 

 frontier. 



The species appears to be generally met with in pairs, although 

 at times in flocks; and Erlanger mentions having shot one of these 

 birds near Medenine, which was in the company of several individuals 

 of C. c. tingitanus, searching for food on some rubbish heaps. The 

 same author obtained from Paul Spatz, of Gabes, a clutch of four 

 eggs, said to be of the present species, which were taken from 

 a tree on March 19th, 1898. The ground colour and marking of 

 these eggs seem to have been a little paler than those of the eggs of 

 C. c. tingitanus. 



According to other authors, C. umbrinus builds its nest in cliffs 

 and among rocks, as well as in trees, depositing from four to six eggs 

 similar to those of C. corax, but richer in colour, and measuring about 

 43 X 31 mm.
