Two new species of the Nematode Genus Rhabdias

Abstract

Several specimens of this parasitic nematode were collected from the lungs of a common British Toad (Bufo vulgaris). They were examined alive, when it was at once apparent that the anterior end was different from that of R. bufonis, in that the body-wall was swollen almost to a sphere and the surrounding cuticle was correspondingly much inflated. It was also noticed that the oesophagus had a slight bulbar swelling towards its anterior end not present in R. bufonis.
