agassii, Orestias Valenciennes [A.] in Cuvier & Valenciennes 1846:238 [Histoire naturelle des poissons v. 18; ref. 1011] Río Corocoro, Peru; San Antonio, Peru. Syntypes: MNHN A-9601 (2) Río Corocoro, A-9602 (6) San Antonio. Type catalog: Bertin & Estève 1950:25 [ref. 19576]. As agassizii on p. xv and on list of plates, agassisii on Pl. 536, and as agassii on p. 238 and on p. 61 of vol. 22 (1849); agassizii is correctly formed for "L'Orestias d'Agassiz." If agassii and agassisii are regarded as typesetting errors, then use agassizii; if not, technically the first reviser apparently is Garman 1895 selecting agassizii but not mentioning the third spelling agassisii. I suppose we should use agassii (selected by Parenti 1994) although it conflicts with has actual name. •Valid as Orestias agassii Valenciennes 1846 -- (Parenti 1984:181 [ref. 5359], Ortega & Vari 1986:18 [ref. 9708], Pequeño 1989:50 [ref. 14125] as agassizi, Dyer 2000:85 [ref. 26678], Lazara 2001:233 [ref. 25711] as agassizii, Costa in Reis et al. 2003:550 [ref. 27061] as agassizii, Lüssen et al. 2004:59 [ref. 29603] as agassi and agassii, Vila 2006:475 [ref. 28797], Vila et al. 2012:352 [ref. 31748] as cf. agassii, Cruz-Jofré et al. 2013:598 [ref. 33015], Sarmiento et al. 2014:99, 187 [ref. 35004], Arratia et al. 2017:S2 [ref. 35512], Esmaeili et al. 2018:17 [ref. 36738]).
