چکیده
The first part of this paper deals with the general geology and geography of the region from which the Cretaceous fishes of Ceara come, while the second part is a systematic description of the fishes themselves. The collection is especially important because it contains all of the species hitherto described from Ceara, besides three new genera and four new species. The large number of duplicates has made it possible to restore several of these fishes almost entirely. The collection belongs to Senhor Francisco Dias da Rocha, proprietor of the Museo Rocha in Ceara, to whom it has been returned, but Sr. Rocha has generously presented several important counterparts and duplicates to the junior author. These counterparts and duplicates are deposited with the geological collections of Stanford University, in California, and of these several specimens have been given to the Smithsonian Institution, at Washington.

Their relations to certain Upper Cretaceous forms had been assumed and they had even been referred to the same genus. An investigation of the question was made possible by the kindness of Dr. T. W. Stanton...
