A LIST OF THE TYPES OF FOSSIL VERTEBRATES 



IN THE MUSEUM OF THE UNIVERSITY 



OF TEXAS. 



THOS. H. MONTGOMERY, JR." 



A considerable number of fossil vertebrates, collected by the 

 geological surveys of the State of Texas under the direction of 

 Mr. E. T. Dumble, state geologist, had been sent to Dr. E. D. 

 Cope for identification. Much of this material is in very frag- 

 mentary condition, but Dr. Cope labelled all the recognizable 

 specimens and described from the collection a number of new 

 species. For ten years or more this material has remained in 

 unopened boxes, as it was returned by Dr. Cope. In the course 

 of the past summer I have arranged these collections in the Uni- 

 versity Museum, and carefully determined all the type material, 

 a comparatively easy task since Dr. Cope had labelled such 

 specimens in almost all cases with the word " type." All the 

 types described by Dr. Cope in the reports of the Geological 

 Survey have been found, with the exception of those of Plianc/icnia 

 spatula and Microdus duniblei. 



Since this valuable material has finally been rescued after so 

 many years of obscurity, it seems advisable to publish a list of the 

 type specimens for the use of students of vertebrate paleontology. 



In this list I have stated the place of first description of each 

 of the species, with the exception of Ddtodcs planidcns and the 

 species of Mesodon : these are not described in the Geological 

 Reports, and I can find no mention of them in the " Zoological 

 Record." Most of the species are described in the " Report on 

 the Paleontology of the Vertebrates," Third Annual Report of 

 the Geological Survey of Texas, published in 1892; and in "A 

 Preliminary Report on the Vertebrate Paleontology of the Llano 

 Estacado," Fourth Annual Report of the Geological Survey of 

 Texas, published in 1893. For the sake of brevity these two 

 papers may be referred to respectively as the " Third Report ): 

 and the "Fourth Report."
