KANSAS PTERODACTYLS. BY S. W. WILLISTON. PART I, WITH PLATE I. The first American species of the singular group of extinct Mesozoic reptiles variously know as Ornithosaurs, Pterosaurs or Pterodactyls was described by Marsh from a fragmentary specimen obtained in 1870, by the Yale College Expedition in Wallace County, Kansas. About a dozen other specimens were obtained by a similar expedition the following year in charge of Professor Marsh, or by Professor Cope, and were described by these authors shortly afterward. By far the largest number of known specimens, however, other than those in the Kansas University Museum, were obtained during the years 1874, ’75, ’76 and ’77 by parties of which Professor Mudge, Dr. H. A. Brous, E. W. Guild, George Cooper and myself were the members, and it was from these specimens that most of the published characters were derived. Many of these specimens are necessarily fragmentary ones, still the material now in the Yale College Museum is ample to elucidate everything of interest concerning these animals. During the past few years, the Museum of Kansas University has been enriched by a series of excellent specimens of these animals, obtained from the same regions, specimens that permit the solution of most of the doubtful characters and throw not a little light on the affinities of the Kansas forms. The species hitherto named are as follows:
