The first haemogregarines to be found in the Salientia of North America were noted by Langmann (1899) from many frogs. Stebbins (1904) described Haemogregarina catesbianae from Rana catesbeiana and (1905) Karyolysus clamatae in R. clamitans and R. pipiens; Kudo (1922) presumably found the same parasites in R. pipiens and R. clamitans. Sanders (1928) noted Lankesterella in R. clamitans and R. catesbeiana and, in addition, she found Karyolysus in R. clamitans. Brandt (1936) found haemogregarines (Karyolysus or Lankesterella) in R. catesbeiana and R. sphenocephala. Fantham et al (1942) described Lankesterella canadensis from R. catesbeiana and Dactylosoma sylvatica from R. sylvatica; they also found haemogregarines in R. pipiens, R. catesbeiana and Bufo americanus. Fowler (1946) found haemogregarines in grass frogs and, finally, Bailey (1948) reported a haemogregarine from R. pipiens. During 1957 and 1958 nineteen Yellow-legged frogs, Rana b. boyli, were collected from Sutter Creek, Amador County, California. Examination of the peripheral blood revealed the presence of sporozoa in the erythrocytes of 7 of the individuals. A portion of the life cycle in the vertebrate host was determined by a study of blood smears and impressions and sections of the viscera. The parasite is dissimilar to the other described species of anuran haemogregarines and, consequently, it is considered a new species. In addition to the description of the new species, inoculations of infected cells were made into presumably uninfected Rana b. boyli.
