Summary Some aspects of the taxonomy and relationships of the barbets are discussed and illustrated, with special reference to the recent classifications of the family by Ripley and by Peters. The colour pattern of the head appears to function as a species‐specific recognition mark. Sympatric species of similar size usually differ strikingly in head colouration. There are several examples of apparent character displacement. The genus Psilopogon is considered to be closely allied to Megalaima. Megalaima lagrandieri forms a link between the two genera. The resemblances between Calorhamphus and Gymnobucco are due to convergence. The latter genus is very closely related to the species placed in Stactolaema. Lybius chaplini is thought to be closer to L. rubrifacies than to L. leucocephalus. The mobility of the rictal bristles of a living Megalaima asiatica is described.
