occur at 55.7, but not enough is known to make a specific reference 

 possible. 



49 — Calymene sp. (Plate I, Figs. 14A, B) — A form of Caly- 

 mene is fairly common at 59.1, 54.8, 54.5 and 54.3 miles from 

 Ludlow, and similar forms occur at 58.8, 58.7, 58.3, 57.8, 56.4, 

 55.7, 55.3, 54.8, 54.7, and 54.3. The genal angles terminate in a 

 spinose point nearly a millimeter in length. 



50 — Calymene abbreviate!, Foerste, was described from the 

 railroad cut a mile south of Rogers Gap. It was characterized by 

 the straightened anterior margin of the glabella, and a low blunt 

 elevation on the frontal border about opposite the anterior exten- 

 sion of the groove separating the glabella from the fixed cheeks. 

 If these characteristics do not prove constant, there is nothing to 

 distinguish the forms found north of Rogers Gap from the Caly- 

 mene abbreviata. The latter species is figured on plate 3 of the 

 Denison University Bulletin, volume 16. 



51 — Calymene granulosa, Foerste, described from the lower 

 Eden at Cincinnati, Ohio, does not occur typically in the Rogers 

 Gap fauna, although the Calymene of the latter fauna is finely 

 granulose, as is often the case with species belonging to this genus. 



Designation of Localities. 



All of the specimens illustrated, unless otherwise indicated, 

 were obtained along the railroad between Rogers Gap and Sadie- 

 ville, in Scott County, Kentucky. The localities indicate the rail- 

 road cuts and their distance from Ludlow. Numerous signs, put 

 up by the railroad, make the identification of the exact cut easy. 

 The milepost 60 from Ludlow is located immediately north of the 

 railroad station at Rogers Gap. The mark for 54 miles from 

 Ludlow is on the railroad bridge in the southern part of Sadie- 

 ville. From these data the relative distance of the various cuts 

 from either Rogers Gap or Sadieville may be determined readily.
