At the first Annual meeting of the Iowa Academy of Science at Iowa City, June 23, 1876, Professor Samuel Calvin read a paper on "New Species of Paleozoic Fossils." The Proceedings of the meeting do not give an abstract of the paper but in the American Naturalist, Vol. 11, pp. 57-58, a brief abstract says that "Prof. Samuel Calvin, of the State University of Iowa, described seven New Species of Paleozoic Fossils found mainly in Howard and Floyd counties, Iowa." One of these species was Rhynchonella alta which occurs in the Lime Creek shales of Floyd County, one of the two counties mentioned. It appears that Calvin distributed "a named photographed plate" of these fossils but its fugitive character has been such that it has not been generally available to students. Calvin's description of the species was not published but we find paleontologists, for example, Williams, Walcott, and others to whom specimens had evidently been sent, accepting the name.
