A new species Renicola glacialis sp. nov., belonging to the trematode genusRenicola, is described.The species is distinguished from most other renicolids by its relatively large size. Two other species within this size range have been recorded; while it is easy to separateR. glacialisfrom one of these species (R. goliathWright, 1957) the poor description of the other (R. secundaSkrjabin, 1924) renders a detailed comparison meaningless. However, the differences in host and geographic location between this andR. glacialisare considered sufficiently great to justify the erection of a new species.The pathology ofR. glacialisis discussed; recently established worms elicit only a slight host tissue response, but older infections are invested by a thick connective tissue sheath. The latter shows maximum development around dead worms and is accompanied by pronounced eosinophilia.Attention has been drawn to the use of the excretory vesicle as a diagnostic character. Four distinctly different forms have been described, and it is suggested that this character, together with certain other morphological features, would provide a useful key for the identification of renicolids once such information is available.

The genera Galactosomum, Microlistrum and Stictodora are compared, and, while the first two are undoubtedly synonymous, the last is considered to be distinct.The adult of the type-species of Galactosomum, G. lacteum, is fully described for the first time from European cormorants, and G. phalacrocoracis is regarded as a synonym.A new species, Galactosomum fregatae, is described from the frigate-bird Fregata magnificens rothschildi.The characters of all the species that have been assigned to Galactosomum are briefly defined, and a provisional differential key is given.
