Abstract:
The larvae which Bontz & Krause in 1930 described in nodules in bovine intestines and believed to be those of Bunostomum have been studied by Monnig who submits conclusive evidence that they belong to the genus Oesophagostomum and probably to the species O. radiatum. Their microscopical appearances are compared with those of the larvae of O. columbianum from nodules in sheep.
