When Packard proposed the najne ^'Argas americana'^ in 1873, he overlooked the fact that Ercolani in 1859 had adopted the name '' Argas americanus Latreille'' for a form which is parasitic on the ears of horses in San Domingo. In 1871, Gamgee also referred to the same form as '' Argas americanus.'' Furthermore, it appears that in 1804, Amblyomma americanum was placed in the genus Rhynchoprion by Hermann. Fig. 78.—Ventr

A. Sanchezi is also probably identical with the chicken 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 Salmon, D.
