Brasilien , Neue Bibliothek. Reisenb., 15:209 . TYPE LOCALITY: Paraguay , Caraguatay Dept., 45 km east of Asunción , Atyra . DISTRIBUTION: E Paraguay and NE Argentina . SYNONYMS: angouya (of Desmarest, 1819), anguya. COMMENTS: Level of differentiation from O. subflavus of E Brazil requires study. Hershkovitz (1959a) mistakenly included O. ratticeps within O. buccinatus , but the two species co-occur in E Paraguay (Cabrera, 1961; Myers, 1982 ). As with other names based on Azara's (1801) characterizations, the clear fixation of this name to a species morphology and the proper usage of angouya Fischer, 1814 , versus buccinatus Olfers, 1818 , should be formally established.
