The occurrence and function of oesophageal glands in some anurans from Tanzania was investigated. The compound glands were present in the oesophageal submucosa of Ptychadena oxyrhynchus Smith, Ptychadena porosissima Steindachner, Phrynobatrachus acridoides Cope, Chiromantis xerampelins Peters, Leptopelis argenteus Pfeffer, Kassins msculats Dumeril, Afrixalus brachycnemis brachycnemis Boulenger, Hyperolius argus Peters, Hyperolius puncticulatus Pfeffer and Hyperolius tuberilinguis Smith, but were absent in Xenopus muelleri Peters, Bufo gutturalis Power and Phrynomerus bifasciatus bifasciatus Smith. It is suggested that in anurans, the oesophageal and gastric glands have similar functions.
