Fascioloides ^ Type (Bassi) 1875. In Uver and lungs of North American herbivores both do- mestic and wild; usually included in former genus. On the advice of Odhner a new genus is made for the North American form. First discovered in a European zoological garden para- sitic in the wapiti, it is known to occur in many hosts and to be widely distributed from Maine to California. It is espe- cially abundant in parts of the South. Egg and embryo are said by Stiles to agree with those of the last species. Fig. 676. Fascioloides magna. Intestinal crura and branches dra\vn as solid black lines. Natural size. (Original.) Another genus, Fasciohpsis, common as a pawisite of man in some parts of the East, has been reported in North America a few times as a human parasite. Apparently all these cases have been imported and the parasite has not so far as known gained a foothold oa this 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 Ward, Henry Baldwin, 1865-1945; Whipple, George Chandler, 1866-1924. joint author.
