New Records of Helminths in British Birds

The object of this short paper is to record a number of new host species for certain common helminths of birds. These new records show that the host range of some helminths is not so circumscribed as had been previously believed. Most of these parasites have been obtained at routine post-mortem examinations and hence were the result of natural infections in the field. A few however were the result of experimental feedings at this Institute.
