Art. XII. Notice of some New Species of Fossils from a Local- 

 ity of the Niagara Group, in Indiana; vrith a List of Identified 

 Species from the same Place. By Prof. James Hall. 



[Abstract from a paper read before the Albany Institute, in April 29, 1862.]* 



Id the autumn of i860, Prof. David Christy of Cincin- 

 nati, called my attention to a collection of fossils made at a 

 locality discovered by himself near Waldron, Indiana, and 

 which he had several times visited during the preceding 

 spring and summer. In this collection I was able to 

 identify a large proportion as known species Of the Niagara 

 group of the New York Reports, while several species were 

 clearly new or undescribed. 



One of the most remarkable features of this collection, was 

 the large number of Eucalyptocrinus, of apparently two 

 species, the greater part of the specimens consisting of the 

 lower part of the body, the arms being removed or but par- 

 tially preserved. Certain species of Brachiopoda were also 

 present in large numbers, and in good preservation ; while 

 the Trilobites were nearly all in a fragmentary condition. 



Prof. Christy very generously gave me all his duplicates, 

 and subsequently placed in my hands his entire collection 

 for description. Mr. S. T. Carly kindly gave me a series of 

 specimens from his duplicates from the same locality; and 

 I am indebted to Mr. U. P. James and Mr. C. B. Dyer for 

 other specimens. I afterwards obtained from the locality 

 a more extensive collection, with some additional species, 

 and the whole enabled me to make a very satisfactory com- 

 parison with the fauna of the Niagara group in other 

 localities. 



At a later period Mr. C. A. White obtained for me 

 a still more extensive collection, which added other new 

 species and increased the number of individuals of those 



* The paper as read before the Institute was a discussion of the geographi- 

 cal distribution of species during the Niagara period, with descriptions given 

 of new species from Wisconsin and Indiana.
