Hartert would call the Didric Cuckoo froni N. W. Africa 

 Chrvsococcvx caprins chrysochlonis Hkink but, as the measure- 

 ments show birds from North West and South Africa cannot be 

 separated. Hartert's remarks (1. c.) clearly emphasise the advisa- 

 bilitv of svstematic ornithologists consulting as large a séries as 

 possible before laving down hard and fast rules. Judged from 

 Tring spécimens alone Hartert was doubtless correct in resus- 

 citating Heine's name for the S. African Didric Cuckoo, but 

 obviouslv Hartert had not consulted the séries in the British 

 Muséum when he wrote the article referred to. See also Sci.ater, 

 Bull. B. O. C, XLH, iq22, p. ii8. 



Until some better character than size can be found \ve must 

 unité ail the White-bellied Didric Cuckoos under one name, with 

 the foUovving enormous range throughout Africa.
