The clutch of three eggs of C. forbesi exhibited was taken by me at Enugu, 6° 25' K, 7° 30' E., Nigeria, on 29th May, 1954. The male was brooding and was collected to confirm identification. The eggs are ovate with the narrow end somewhat compressed. The ground colour is cream tinged with pink. The markings take the form of evenly distributed rather blurred blotches and spots of sepia and olive-brown, and the ashy secondary suffusions and blotches are prominent and thickly distributed. There are no hair lines or other linear markings. They measure x , x 23, x mm. The eggs are altogether different in ground colour and markings from those of C. tricollaris. On the evidence of the eggs alone these two forms cannot be considered conspecific. There is one previous record of the breeding of C. tricollaris, also from Nigeria—by Brown (Ibis, 1948, pp. 529-531). From the description the eggs seen by Brown closely resembled those obtained at Enugu. Geographical Variation in the Southern African Populations of Dicrurus adsimilis (Bechstein) by Mr. P. A.
