Abstract

The tadpole of Altiphrynoides osgoodi is described on the basis of material collected in 1975 near Goba, Ethiopia. The tadpole resembles typical bufonid tadpoles in its general shape and size, but differs in several characters from other known African bufonid tadpoles. It is characterized by very large nostrils and an indistinct (in preservative), but long, slitlike spiracular aperture. The buccopharyngeal morphology is overall similar to that reported for other African bufonids and shows the most similarities with Schismaderma carens. The gut of a Gosner stage 34 tadpole contained items that were apparently ingested as well as large amounts of yolk within the intestinal tissue, suggesting that A. osgoodi tadpoles may be facultatively nonfeeding.
