2 FLOKA OF LOWER COAL MEASTJEBS OF MISSOURI. 



ACKNOWLEDGMENTS. 



Acknowledgments are due, first of all, to Dr. J. H. Britts, of Clinton, 

 for the use of types and other specimens identified by Pi'ofessor Lesque- 

 reux; also to the Director of the United States National Museum for facil- 

 ities for the stud}^ of the Missouri plants, including a number of types 

 formerly in Professor Lesquereux's private collection, but afterwards 

 secured by Mr. R. D. Lacoe, of Pittston, Pennsylvania, and now become, 

 by the gift of the entire collection of the latter, the property of the National 

 Museum. 



COELECTIONS AND LOCAEITIES. 



The Paleozoic plant material described from Missouri has generally 

 been recorded with no other localizations than "Clinton" or "Henry 

 County, Missouri"; and while it is of great paleontologic importance, it will 

 in this report be treated geographicall}^ as one lot, since, unless otherwise 

 stated, it all came from one horizon in a single district. Out of several 

 boxes of specimens from stated localities in this county forwarded to the 

 United States National Museum in January, 1891, by Dr. Bi-itts, a number 

 of specimens were found which, owing perhaps to fracture, abrasion, etc., 

 have no exact localization, though coming from the same locahties as some 

 of the others. These have the "lot catalogue" number 342, U.S.Gr.S. 



Pitcher'' s coal mine, 3^ miles southeast of Clinton. Collections were 

 made at this mine by Mr. Gilbert Van Ingen, assistant in the United States 

 Geological Survey, and forwarded September, 1890. Mr. Van Ingen's 

 collection, which includes many fine ferns and slabs of Lepidodendron, 

 constitutes lot 407 from United States Geological Survey station 1263 D. 

 Plants from the same locality were sent to the National Museum by Dr. 

 Britts in January, 1891, and became lot No. 340. 



Oioens\s coal mine, 2 miles southeast of Clinton. Many specimens from 

 Owens's coal mine were sent to the National Museum by Dr. Britts in 

 January and in April, 1891. These will be referred to as lot No. 339. 

 Another large consignment, obtained in the process of "stripping" neai 

 tliis coal mine, was forwarded by Dr. W. P. Jenney, of the United States 

 Geological Sm-vey, in October, 1891, while investigating the zinc deposits 

 of southwestern Missouri. These specimens form lot No. 411.
