Whlle making studies of the parasites of fishes and amphibians at the Pacific Marine Station, Dillon Beach, California, during August, 1949, the writer encountered a hitherto unreported trypanasome from a female Triturus torosua. From the information obtained from the one smear, which was stained, the animal was presumed to be monomorphic, However, during February, 1950, a search was made expressly for the purpose of' obtaining specimens of this Pacific Coast newt, and of the eight animals examined six were parasitized. Contrary to the primary observations, evidence was accumulated which proved beyond any doubt that the flagellate is polymorphic and that, evidently, it has not been reported or described. The name Trypanasoma barbari is proposed for this species.
