EARLY DEVONIC HISTORY OF NEW YORK AND EASTERN NORTH AMERICA 93 



Drs A. Smith Woodward and C. Davies Sherborn. These collections from 

 Horeb Chapel and Felindre in Wales; Bradford, Whitecliffe, Ludford, 

 Brindgwood Chase, Ombury, Downton, Hargeest Mill and other localities, 

 supplement an excellent series of specimens presented years ago to the 

 State Museum by Sir Roderick Murchison when director general of the 

 geological survey of Great Britain. Cautious examination and comparison 

 of this material with that from Aroostook county show a possibility of only 

 remote and indirect comparison, too frail to justify extended discussion, 

 sufficient to indicate that the Tilestones of Wales and Ludlow are unlike 

 quantities faunally, and that in no particular worthy of serious consideration 

 is there any substantial organic resemblance between either and those under 

 present consideration. 



It will be found on reference to my very brief published comments on 

 this fauna that a strong affiliation was indicated to the Coblentzian of the 

 Rhineland. In my restudy of the fauna, of which the present presentation 

 is the result, I have to acknowledge the generous aid which has been 

 afforded by Prof. E. Kayser of Marburg and Dr F. Drevermann of Frankfort, 

 who have supplied me with series of specimens and have made comparisons 

 of and commentaries upon my own determinations. With such assistance, 

 some personal field acquaintance with the European faunas and with the 

 help of considerable series of Coblentzian material already in the State 

 Museum, it has been possible to secure in dependable measure the accuracy 

 of determinations and comparisons with Coblentzian species. It is in this 

 resemblance with the rhenish lower Devonic that the faunas of the Chap- 

 man Plantation find their most pronounced character in contrast with those 

 of a more strictly American type. This fact is forcibly brought out by 

 study of the tabulation given on a following page. 



Stratigraphy of the Chapman Plantation 



The outcrops which have afforded the fossils here discussed occur in 

 two areas : (i) in the upper reaches of Presque Isle stream over an area 

 bounded by that stream, Shields brook and Alder brook lying in the 

 southern part of the Plantation ; (2) Edmunds Hill, a small outlier near
