This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1898 edition. Excerpt: ...names, indicating a differentiation of the species, have been used in the literature of the subject: G. pitcheri Morton. G. tucumcarii Marcou (also Or. dilatata var. tucnmcarii Marcou). G. pitcheri var. navia Hall. G. pitcheri var. Navia Conrad. G. navia Hall Gabb (assigned by Gabb to Conrad). G. washitaensis Hill. G. gibberosa Cragin. G. newberryi Stan ton. G. pitcheri var. hilli Cragin. Exogyra forniculata White. According to the law of priority, only the following names for the forms called G. pitcheri in the list above given can survive, and these, with certain others to be introduced, will hereafter be used in this paper: G, corrugata Say. In accordance with the laws of priority, this has precedence over G. piicheri Morton, G. tucumcarii Marcou, G. dilatata var. tucumcarii Marcou, G. pitcheri var. hilli Cragin, and G. hilli Cragin. G. navia Hall. The synonyms G. roemeri Marcou and Exogyra forniculata White must be abandoned. G. mucronata Gabb, 1861, must supersede G. pitcheri var. navia in part as applied to Roemer's G. pitcheri. G. washitaensis Hill, of which G. gibberosa Cragin is a very old form. G. neu-berryi Stanton. In the succeeding chapter, which deals with the systematic classification of the species, this list will be still further modified by the introduction of two new specific names, so that the list of all the above forms will be as follows: Gryphaea wardi sp. nov. Gryphaea marcoui sp. nov. Gryphtea corrugata Say. G. corrugata var. tucumcarii var. nov. G. corrugata var. hilli Cragin. G. corrugata var. belviderensis var. nov. G. navia Hall. G. washitaensis Hill. G. mucronata Gabb. 1 Contributions to the invertebrate paleontology of the Texas Cretaceous: Fourth Ann. Kept Geol. Survey Texas, pp. 189-190, Austin, June, ...
