Flora of Abyssinia^) wheu he passed through Aden at the 

 time of the Abyssinian Expedition as C. affinis, but I think 

 tliey were all defunct wheu I returned to Aden in 1882. 



Crows breed in the rocks outside the Isthmus position 

 and in the doum palms at Shaik Othman, at which latter 

 place Capt, Nurse told me he took a nest containing four 

 eggs on the 25th March, 1895,

A resident, breeding in many places in the crater at Aden. 

 It is very common, too, at Lahej and Shaik Othman.

Very common in flocks in the big baubul-trees at Shaik 

 Othman and on the road to Lahej. This is probably the 

 Uroloncha of Barnes's list. Capt, Nurse informs me that he 

 found a nest of this bird, containing two pure white eggs, 

 at Shaik Othman on the 25th of March, 1895,

Although not included in Mr. Barnes's list, I knew of the 

 existence of tliis bird at Lahej, where it is very common, 

 before I left Aden in 1885. One or more big flocks have 

 established tiiemselves now in Aden itself, breeding in the 

 thorny trees at the tanks and alongside of the gaol-wall. 

 They are gregarious and build a thick nest of thorny twigs. 

 The eggs vary somewhat in markings and size. A clutch 

 contains three eggs, and one taken by Capt. Nurse in May 

 1894 has been handed over to the British Museum.
