Art. XLV.—On the Fauna fotantt at Lime Creek, Iowa, and 
its relation to other Geological Faunas; by S. CALVIN,: State 
University of Iowa. 
A PAPER by Professor H. 8. Williams, in this Journal for 
February, 1883, “On a remarkable Fauna at the base of the 
Chemung Group i in New York,” appears to me to record more 
than one remarkable aiasoveey: The finding of fossil peice 
at High Point, New York, identical with species that hav 
heretofore been known only fr from the Rockford Shales, atone 
Lime Creek above Rockford, tows is a most interesting fact 
and well deserves immediate record. In discussing the signifi- 
cance of his discovery, however, the author of the above-men- 
tioned paper, misled no doubt by information from untrust- 
worthy sources, bas fallen into a few errors pone in the interest 
of clearness in geological matters, should be set 
For the better understanding of the aueinious involved let 
me give a catalogue of the Lime Creek fauna as far as the 
species have been described. Some of the species enumerated 
below have not been catalogued from this locality by previous 
writers, but my own collections, made personally, embrace all 
the species of this list, except Letorhynchus iris which is in- 
cluded on the authority of Mr. R. P. Whitfield.
