Abstract: Previous workers have suggested that uraeotyphlid caecilians are probably oviparous with direct development. Contrary to these suggestions Uraeotyphlus oxyurus has a larval stage with typically larval morphological features including a lateral line system, 'spiracles', and labial folds. Two larvae and one metamorphic specimen of U. oxyurus are described and aspects of their morphologies compared to that of adult Uraeotyphlus, the larvae of other caecilians and to that of aquatic adults of the Typhlonectidae. Gut contents indicate that the larva of this species is not a highly abbreviated non-feeding life history stage.
