Trematodes of the genus Renicola from birds in British zoos, with descriptions of two new species



A number of cases of infection of the kidneys in birds by trematodes of the genus Renicola Cohn, 1904 is reported and two new species of the genus are described. One of them, Renicola pelecani sp. n., has been found in both the White Pelican (Pelecanus onocrotalus) and the Spot-billed Pelican (Pelecanus phillipensis). The other, Renicola sloanei sp. n., has been found in a number of species of penguin. It has also been found in a Common Guillemot (Uria aalge) from Sussex, this being the first record of a Renicola from a wild bird in Great Britain.
