PROCEEDINGS OF THE UNITED STATES NATIONAL MUSEUM issued B^?NvA, Q?l^l h ihe SMITHSONIAN INSTITUTION U. S. NATIONAL MUSEUM Vol. 83 Washington: 1935 No. 2978 ON THE REPTILIA OF THE KIRTLAND FORMATION OF NEW MEXICO, WITH DESCRIPTIONS OF NEW SPECIES OF FOSSIL TURTLES By Charles W. Gilmore Curator, Division of Vertebrate Pahontologij, United States National Museum The present paper records the results of a study of a small collection of reptilian specimens in the United States National Mu-seum from the Kirtland formation of New Mexico. It is a third contribution on this subject, as I have considered this fauna in two previous articles (Gilmore, 1916 and 1920). The materials were acquired (1) by a field party from the National Museum working under my direction, which spent the summer of 1929 collecting in the San Juan Basin; (2) by purchase of a small lot of turtles from C. H. Sternberg collected in 1923; and (3) by gifts from individuals or by transfer from the United States Geological Survey of a small but varied assortment of specimens. Study of these shows the presence of several new species of turtles, and other well-preserved specimens contribute to a better understanding of forms previously known. The recovery of additional though incomplete dinosaurian spec-mens is of interest in showing the presence of forms other than those previously reported. It is proposed to review briefly those dino-saurian species that are now in other museums but that have been described since the appearance of my 1920 paper. Thus all the new information relating to the extinct vertebrate fauna of the Kirtland formation is brought together in this one article. 116009—35 1 \m
