Twenty-four species of fossils from the Maxville lime- 

 stone have been described and illustrated b}- Whittield. The 

 present study 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 C(jmplete as possible, these thirty- 

 six species are described and illustrated in the following pages, 

 and with the exception of those after Wdiitlield the illustrations 

 are either camera lucida drawings or actual ])h()t()graphs by the 

 author. 



The bibliography of each species has been made as complete 

 as possible simply for convenience, and in (piestions of synonomy 

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

 ican Carboniferous Invertebrates has been followed. The hori- 

 zon and locality from which the descriljed 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 carefull}' located in Bulletin 13. it will ])r()bal)l}' be 

 more convenient for some readers if the location of each be 

 again briefly described. A\ ith the exception of the I^arper 

 Shaft, ^\•hich is near Olive b\n-nace in the Southern Area, all 

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

 Jonathan Creek, the Bridge Gully, Cuts Xo. 2 to Xo. 6, and the 

 Mouth of Hough Hollow are between Alt. Perry and b^dton- 

 ham. the Alouth of Buckeye Fork and the Xorth B)ank are just 

 below Fultonham, and Gladstone Mill is at White Cottage. 

 The Kroft Residence, the Kroft Bridge, and the Thompson 

 Residence are located along the lower portion of Rents Run 

 within a mile of White Cottage. \\'est Jockey I lollow crosses 

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

 of Rnshville and the Folk Quarry is located on the Zanesville 

 and Maysville Pike a like distance east of the same village. 

 The Stimmel Residence is about a mile north of Maxville and 

 Smith Cha])el aljout two miles south-east of Logan.
