2. — To apply this critical determination of D'Orbigny's Viennese species to our study of the Cretaceous ROTALINAE, we must group them in their natural order, so as to render them comparable with the Table of Cretaceous Rotalines appended to this memoir ; we must also insert with them such other forms from the Vienna Tertiary beds as Czjzek, Reuss, and Karrer have discovered.

Those figured and described by Karrer are as follows : —

Anomalina Suessi, Karrer *. Sitzb. Ak. W. 1861, xliv. pl. 2. f. 2. A very much compressed Anomalina austriaca, D'O. From Odenburg.

Rotalia speciosa, Karrer. Sitzb. Ak. W. 1864, pl. 2. f. 12. Anomalina coronata, P. & J. From Baden.

Rotalia scutellaris, Karrer. Sitzb. Ak. W. 1864, 1. pl. 2. f. 13. Planorbulina Haidingerii (D'O.), subvariety. From Modling.

Rosalina granulosa, Karrer. Sitzb. Ak. W. 1864. 1. pl. 2. f. 14. Cymbalopora granulosa (Karrer). From Forchtenau. Rotalia tuberosa, Karrer. Sitzb. Ak. W. 1867, lv. pl. 1. f. 4. Rotalia Schroeteriana, P. & J. From Laa, Lower Austria.

Globigerina arenaria, Karrer. Sitzb. Ak. W. 1867, lv. pl. 1. f. 10. (Non Globigerina.) Discorbina? From Grund, Lower Austria.
