 HUNTINGTON. Explorations in Turkestan, rrith an Account of the 

 Basin of Eastern Persia and Sistan. Expedition of 1903. Quarto, 

 xn-f-324 pages, 6 plates, 174 text figures. Published 1905. Price $4.00. 



Besides the archeological and physico-geographical report by Professor 

 Pumpelly, on his reconnaissance in Turkestan, Publication No. 26 contains a report 

 of nearly 100 quarto pages by Prof. William M. Davis, of Harvard University, 

 mainly consisting of a geological study of Turkestan. Mr. R. W. Pumpelly con- 

 tributes physiographic observations between the Syr Darya and Kara Kul, on the 

 Pamir, and Mr. Ellsworth Huntington, of Yale University, contributes two paper?, 

 entitled, "A Geological and Physiographic Reconnaissance in Central Turkestan" 

 and "The Basin of Eastern Persia and Sistan."

 The Cambrian Faunas of China, 24 plates, 9 figures; by CHARLES D. WALCOTT. 

 A Report on the Ordovician Fossils collected by the Carnegie Institution Expedition 



to Eastern Asia, 2 plates; by STUART WELLER. 



Report upon Upper Paleozoic Fossils from China collected by the Carnegie Institu-

Volume I, Part I, contains observations relating to the geology of northeastern, 

 northern, and central China (Shan-tung, Chi-li, Shan-si, and Shen-si). The treat- 

 ment is primarily by districts, and under each district the terranes observed are 

 described in order from older to younger. The nature and succession of strata, the 

 fossils, and the structure of each terrane are discussed. The terranes observed may 

 be enumerated as follows : Pre-Cambrian, Cambrian, Ordovician, Devono-Silurian 

 (in Central China only), Carboniferous, Permian (?), Jurassic, and Quaternary. 

 The principal contributions to knowledge relate to the Pre-Cambrian, the strati- 

 graphy and fossils of the Cambrian and the history of the Quartenary. The last 

 named comprises an analysis of the mountain forms in terms of uplift and erosion 

 and a discussion of the loess. A unique feature is the account of an early Cambrian 

 tillite or glacial till, which underlies the Cambrian limestone of the Yang-tzi valley. 

 The volume is profusely illustrated with photographs of the scenery of the mountain 

 districts of Chi-li, Shan-si (the land of the loess), and Shen-si. 



The atlas contains 2 route maps, 20 topographic maps, and 20 identical geologic 

 maps. The topographic maps represent the features along and adjacent to the route 

 on a scale of 1 : 125000, with 100-foot contours. They are based on plane-table sur- 

 veys and the forms of the land were sketched expressively in contours on the spot. 



Vol. I, Part II, includes three special reports which are subsidiary to the general 

 treatment of the geological observations in Part I of the same volume. 



The first and largest section contains a description of the varieties of igneous, 

 metamorphic, and sedimentary rocks collected by the expedition in China. All of 

 these specimens come from northern China, the majority of them being from Shan- 

 tung, western Chi-li, eastern Shan-si, and southern Shen-si. The collection com- 

 prises typical representatives of the .geological systems from Archean to Mesozoic, 

 Of special importance are the description and interpretation of the varied oolitic 

 and conglomeratic limestones found in the Cambrian terrane. 



The second section, dealing with zoological observations, includes an annotated 

 list of the amphibians, reptiles, and birds observed. About 130 species of birds are 

 noted and of these 6 of the least known are illustrated by beautiful colored plates. 



The last section contains a syllabary of Chinese sounds, prepared by Professor 

 Hirth, of Columbia University. The orthography recommended by the author it
