456 JR. T. Hill — The alleged Jurassic of Texas. 



Professor Marcou has long imagined that brief observations 

 in these outlying areas have constituted him an authority on 

 the greater Texas region which he has not seen, and made 

 them the basis for creating, at his study at Cambridge, such 

 tabulations as above mentioned and dictating where work 

 should and should not be done in the Cretaceous region of 

 Texas. This article under discussion is especially profuse in 

 such suggestions. I can dismiss them in a lump as follows : 

 The monograph on the fossils which have been called 

 " Gryphcea pitcheri" was written and ready for the printer a 

 year ago, and was transmitted to the Director for publication 

 on January 13, 1897. When it does appear it will further 

 show by the most conclusive stratigraphic and paleontologic 

 data, together with a careful study of the development of the 

 forms, the identity of his alleged Jurassic species from Tucum- 

 carri with the forms called " Gryphwa pitcheri " in the 

 Cretaceous of Texas, and the form which he names Gryphwa 

 Teansana (page 203) from Kansas. For the two or three speci- 

 mens of the last mentioned form which he states that he 

 possesses, and which I have seen in his studio at Cambridge, 

 we possess hundreds of specimens showing every stage of the 

 development. Futhermore Mr. T. W. Stanton is now solely 

 engaged upon the descriptive paleo-zoology of the Cretaceous 

 of Texas, a work which 1 had to abandon owing to pressure of 

 other duties, and his work will be reliable and authoritative. 

 Professor Lester F. Ward is likewise studying in a similar 

 manner the paleo-botany. 



Prof. Marcou's remark about "special need of investigation 

 in the vicinity of Austin and Fredericksburg" can be fully 

 answered by stating that in addition to my previously pub- 

 lished papers on this region, there is in type for the Eighteenth 

 Annual Report of the IT. S. Geological Survey a large and 

 comprehensive work upon this region by Mr. Yaughan and 

 myself, giving every detail of its stratigraphy with maps and 

 illustrations. Furthermore, we have in process of publication, 

 four atlas sheets of this region. I have also personally con- 

 ducted Mr. Stanton over this country, and he is illustrating and 

 describing the paleontology as fast as accurate methods will 

 permit. He has just returned from that region, where he has 

 made additional collections. 



We have already shown that his charges that his opponents 

 will not visit his localities are unjust. Just one year ago when 

 I lay at Muskogee, Indian Territory, upon what was then 

 supposed my death-bed, I turned over my camp equipment to 

 Professor Lester F. Ward and Mr. T. Wayland Yaughan, and 

 requested them to visit the Kansas localities, which they did. 

 Mr. Yaughan also thoroughly studied all the outlying areas to
