Dr. Teichert was a member of the United States Aid mission of Pakistan and his Salt Range studies were an official part of his assignment to this mission. Drs. Nor- man Sohl and Curt Teichert critically read the manuscript and offered many helpful comments for which I am grateful. HISTORY OF RESEARCH The first serious study of the succession of strata in the Salt Range of ^^'est Pakistan was carried out by Andrew Fleming in the middle of the 19th centuiy. One of the more important aspects of Fleming's work in the Salt Range was the collection of a suite of fossils. These were sent to England and were studied and described by such contemporary celebrities as Sir Roderick Murchison and Thomas Davidson in En- gland, E. de X'erneuil in France, and L. de Koninck in Belgium. It was the suite of fossils studied by de Koninck (1863) that provided the first indication of the "Second- ary formations" in the Salt Range. The cir- cumstances can best be related in de Koninek's (1863, p. 1) own words: "Among these fossils, certain species belong to genera that have hitherto only been found in the Secondary formations, and occur princi- pally in the lower groups of that great geo- logical period. Such, above all, are the Ceia- tites, which appear to be tolerably abundant in a rock of the Punjaub Salt-range, and are remarkable from the fact that they are all new to science. But for this last circumstance, one might have entertained
