COLLECTIONS AND LOCALITIES. 3 



Hohhs's coal mine, iu SE. \ sec. 13, T. 40, R. 26, 8 miles south and 2 

 miles east of Clinton. A considerable number of specimens sent by Dr. 

 Britts from this locality in January and April, 1891, comprise lot No. 341. 



Deepwafer. A large quantity of specimens " designated by this name 

 came from a mine 8 miles southeast of Clinton. It is very close to the 

 locality quoted as the Hobbs mine. These plants, forwarded to the United 

 States Geological Survey by Dr. Jemiey iu June, 1891, form lot No. 408. 

 Another consignment, sent by Dr. Jenney and Dr. Britts in October, 1891, 

 bears the lot number 413. 



Gilkerson's Ford, Grand River, 5 miles south of Clinton. Very finely 

 preserved plants in calcareous iron concretions were forwarded to the United 

 States Geological Survey by Dr. Jenney in October, 1891 (lot No. 412), 

 and by Dr. Britts in September, 1892. A small collection from shales 

 in this vicinity was also sent b}^ Dr. Britts. The latter sjDecimens, which 

 were found at a lower horizon than the ironstone concretions, were engraved 

 with "G. F." by the collector and donor. They contain a number of the 

 best-preserved and most interesting plant remains. 



Near Jordan^s old coal mine, 5 miles south of Clinton, from black shales 

 overlying the coal in the North and Wood shaft. These specimens, consist- 

 ing of Sigillaria, mostly decorticated, and occuriing immediateh^ below the 

 other plant shales, were forwarded by Dr. Britts in April, 1891. They con- 

 stitute lot No. 404. 



Those specimens which I have seen represented only in the Lacoe 

 collection are referred to by the numbers in the special catalogue of that 

 collection. 



A number of plants which were sent by Dr. Britts iu small special 

 packages were not given lot numbers, and will be localized in full when 

 discussed. 



Vernon County. The specimens of Conostichus described in the Coal 

 Flora have no other locality reference than Vernon County, Missouri. From 

 the statements of the geologists of the State it seems probable, however, that 

 the types now in the Lacoe collection, United States National Museum, came 

 from Big Drywood Creek, 5 miles south of Deerfield.-'
