PART II.— FOSSIL FAUNAS OF DEVONIAN SECTIONS IN CENTRAL AND 
NORTHERN PENNSYLVANIA. 
By H. 8. Williams and E. M. Kindle. 
PREFACE. 
By H. 8. Williams. 
The sections discussed in the following pages were chosen for the 
purpose of extending the detailed knowledge of the faunas of the 
Devonian in a southeasterly direction across the beds from central 
New York, where the writer had already accumulated considerable 
evidence of their order and composition, to central Pennsylvania. 
The facts already known suggested the probability that in Devonian 
time a shore line to the southeast limited the basin in which the sedi- 
ments accumulated and the forms lived; the}^ also led to the expecta- 
tion that there would be a modification of the faunas to some degree, 
according to their distance from the shore line. 
While the writer planned and directed the investigations, Doctor 
Kindle examined the sections and collected and identified the fossils. 
In the interpretation of the facts we have worked together and have 
reached the same conclusions. To the discussion, however, we have 
each contributed. The preparation of charts and faunal lists and 
method of treatment has been, in general, under the direction of the 
senior author, but the junior author has contributed many valuable 
suggestions and has done the most valuable part of the work — the 
gathering and elaboration of the facts themselves. 
The following sections have been examined, and the order of succes- 
sion and composition of the temporary f aunules analyzed and reported 
for each: 
The Catawissa section, East Bloomsburg, Columbia County, Pa., 
about 76° 30' west longitude, and a little south of 41° north latitude.
