1. Genus Pseudomonotis Beyrich.
1862. Zeits. deutsch. geol. Gesell., Bd. xlv, p. 9.
Genotype (by subsequent designation, Stoliczka, 1870, p. xxi):
Gryphites speluncarius Schlotheim, Zechstein, Europe.
Stoliczka, as early as 1870, designated as type of Pseudomonotis the Permian P. speluncaria (Schloth.), and in this he was followed by Fischer (Manuel, p. 954). Pseudomonotis must therefore always include the short-hinged group of Permian species which have been recorded from Europe (P. speluncaria, radialis Phil., kazanensis Vern., garforthensis King), India (P. radialis, kazanensis, garforth-ensis) and North America (P. hawni Meek and Hayden). Meek, who was unaware of the prior Pseudomonotis, in 1864 proposed for

this group Eumicrotis, genotype Monotis hawni Meek and Hayden, a Kansas Permian species having sculpture and shape similar to those of speluncaria. His name therefore falls as a synonym of Pseudo-monotis and cannot be used for any of the other groups mentioned.
J. P. Smith (1927, p. 120) gave the type of Pseudomonotis as P. ochotica, stating that “Beyrich named no type… but made it clear that he meant this particular group.” Stoliczka's (and Fischer's) designation, however, appears to be quite valid and consequently is “not subject to change.” (Internat. Rules, Art. 30, 11, g.).
