Remarks
The deep sutural groove on the ampullinid specimen from the Caballas Formation is a diagenetic artefact created by shell material dissolving from between gypsum-filled internal moulds of successive whorls. Thus, the Caballas specimen is not an example of the deeply grooved Ampullinopsis Conrad, 1865 , which is considered by MacNeil and Dockery (1984) to have an exclusively Oligocene record in Europe and the Americas. The specimen of Ampullina ortoni has a thin shell, appressed sutures, and no surface spiral sculpture, contrasting in the last named character with the spirally lined Ampullina gabbi Woods, 1922 , from the Salina Group of Gonzáles (1976).
Olsson (1944) described three new species of Ampullina from the late Campanian beds of the Tortuga Formation in the Sechura Basin of northern Peru: A. breccia Olsson, 1944 , A. tortuga Olsson, 1944 , and A. cumara Olsson, 1944 . The moderately high spire, non-sinuate columella, and elongate elliptical aperture of the Caballas Formation example of A. ortoni most resemble comparable features in A. breccia . Ampullina breccia , however, like the Eocene A. gabbi , has faint spiral threads, which the specimen of A. ortoni lacks, judging from an inspection of a well-preserved external mould from the Caballas Formation.
