Twenty-four species of fossils from the Maxville lime- 

 stone have been described and illustrated by Whitfield. The 

 present stucty has resulted in the discovery of twelve additional 

 species which are new to the stratum. Pursuant to the original 

 idea of making the report as complete as possible, these thirty- 

 six species are described and illustrated in the following pages, 

 and with the exception of those after Whitfield the illustrations 

 are either camera lucida drawings or actual photographs by the 

 author. 



The bibliography of each species has been made as complete 

 as possible simply for convenience, and in questions of synonomy 

 the arrangement in Weller's Bibliographic Index of North Amer- 

 ican Carboniferous Invertebrates has been followed. The hori- 

 zon and locality from which the described specimens came have 

 also been added to the bibliography so that a glance would suf- 

 fice to show both their geologic range and geographic distri- 

 bution. 



Although sections have been made at practically all of the 

 places mentioned in the following "Table of Distribution" and 

 each one carefully located in Bulletin 13. it will probably be 

 more convenient for some readers if the location of each be 

 again briefly described. With the exception of the Harper 

 Shaft, which is near Olive Furnace in the Southern Area, all 

 of the localities are in the Northern Area. Of those along 

 Jonathan Creek, the Bridge Gully, Cuts No. 2 to No. 6, and the 

 Mouth of Hough Hollow are between Mt. Perry and Fulton- 

 ham, the Mouth of Buckeye Fork and the North Bank are just 

 below Fultonham, and Gladstone ^lill is at White Cottage. 

 The Kroft Residence, the Kroft Bridge, and the Thompson 

 Residence are located along the lower portion of Kents Run 

 within a mile of White Cottage. West Jockey Flollow crosses 

 the "State Road" at a point about three and a half miles east 

 of Rushville and the. Folk Quarry is located on the Zanesville 

 and A^Iaysville Pike a like distance east of the same village. 

 The Stimmel Residence is about a mile north of Maxville and 

 ♦ Smith Chapel about two miles south-east of Logan.
