P. aequilatus, Amegh., 1901, Bol. Acad. Nac. Cienc. Cordoba, t. 16, p. 371.
This species is based on the anterior lobe of each lower molar, being longer than the posterior. In size, molars 1 to 3 measure 24 mm.[13]
Phanophilus Ameghino
Phanophilus, Amegh., 1903, Anal. Soc. Cienc., Argen., t. 56, p. 202.
This genus is based on isolated upper molars, characterized as similar to Protypotherium, but having a pronounced median vertical column, instead of a groove on the external face of the upper molars, a character unique among typotheres. The position of the genus with this scant information is uncertain. One species is described, P. dorsatus.
Phanophilus dorsatus Ameghino
P. dorsatus, Amegh., loc. cit. p. 202.
In our collection, two isolated upper molars of this unusual form occur, corresponding in size and pattern to the one described by Ameghino. The external column, as seen by [fig. 42], is narrow and high. A single tooth measures 5½ mm. from front to back, and 3¾ mm. in width.
