It comes rather close to 0. copei., also to 0. hylaxena^ from georgiana^ but the general impression from the tri- angulata infections is quite different from that given by an infection of either of the forms mentioned. Some individuals of O. panamensis are of similar shape, but they have much larger nuclei, averaging one and one-half tnicra Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States National Museum; Smithsonian Institution; United States.
