384 G. II. Girty — Fauna found in the Devonian 



Art. XXXVII. — Description of a Fauna found in the 

 Devonian Black Shale of Fastern Kentucky;* by George 

 li. Girty. 



Fossils have been found at so few localities in the Devonian 

 black shale of Ohio and the southern Appalachian region gen- 

 erally, and those constituting so limited a fauna, f that any 

 additional imformation in either particular should not bo with- 

 out interest. 



The collections which furnish the subject-matter for this 

 paper were made by M. K. Campbell and L. C. Glenn of the 

 U. S. Geological Survey from two localities in eastern Ken- 

 tucky, and in both instances come from near the base of the 

 black Devonian shale. 



The following lists show the fauna collected from these 

 localities : 



Oil springs on Lulbegrud Creek, two miles southeast of Indian 

 Fields, Clark Co., Kentucky. 



Lingula (Lingulipora) Williamsana n. sp. 

 Leiorhynchus quadricostatum Vanuxem. 

 Prioniodus armatus Hinde. 

 Sporangites Huronensis Dawson ? 



Two miles southwest of Jefferson ville, Montgomery Co., Ken- 

 tucky. 



Lingula {Lingulipora) Williamsana n. sp. 



Orbiculoidea sp. 



Leiorhynchus quadricostatum Vanuxem. 



Meristella cf. Haskinsi Hall. 



Plethospira socialis n. sp. 



Sporangites Huronensis Dawson ? 



Further collections at these localities would probably bring 

 to light a much more extensive fauna than these lists contain. 

 Indeed, Linney mentions, besides the remains of plants and 

 fishes, a species of Bellerophon and an Orthoceras. These 

 invertebrates, he says, are replaced by pyrites, as is the case 

 with the gasteropod shell described below. Leiorhynchus, 

 r however, as it appears in my collection, is a mere impression, 

 though the shell substance of Meristella seems to be retained, 

 while Lingula, as is usual, presents dark, shining phosphatic 

 surfaces.

\ In the Genesee of New York State a much more abundant fauna is known. 

 Clarke mentions forty-three species (six being plants) from the Genesee rocks of 

 Ontario Co. (Bull. U. S Geol. Surv., No. 16, p. 33). which with twelve species 

 identified by other authors from the State of New York, makes a total of fifty-five.
