The genus Entamoeba, Casagrandi and Barbagallo 1895, includes a number of species parasitic on a wide range of animals from ciliates to man. Many of these are morphologically similar but differ in growth requirements and hosts. Entamoeba histobtica, Sohaudinn 1903, in man, and Entamoeba invadens, Rodhain 1934, in snakes, are the only two species known to invade host tissue. In 1930 Sanders and Cleveland described a new species, Entamoeba terrapinae, from the terrapin, Chrysemys elegans. Since then no further work has been pablished on this amoeba, and much information regarding it is still wanting. According to Sanders and Cleveland the life-cycle of E. terrapinae differs from any other life history of a parasitic amoeba heretofore described. As their observations have not been confirmed it was deemed advisable to reinvestigate the life-cycle of this parasite. A number of species of parasitic amoebae have been described in turtles by various workers. In many of these the specific identity, which was established on inadequate morphological study, is still in doubt. In some cases size alone was the characteristic used for differentiating a species. In the present investigation a detailed study of the morphology of Entamoeba terrapinae has been made. In an attempt to evaluate morphological characteristics and size as taxonomic characters a comparison of the morphology of Entamoeba terrapinae with that of two morphologically similar species [...]
