III. — Cambhian Faunas of China. By Charles D. "Walcott. 

 From Proceedings United States National Museum, vol. xxx, 

 pp. 563-595. 8vo. (Washington, 1906.) 



rilHIS is the second preliminary paper on the Cambrian Faunas of 

 _J_ China. In the first paper (Proc. U.S. Nat. Mus., xxix, Sept., 

 1905, pp. 1-106) a historical introduction was given along with 

 a list of the species known at the time of publication. 



During the summer of 1905 a collection made by Mr. Eliot 

 Blackwelder was received, which came chiefly from the provinces of 

 Shen-si and Shan-si. This collection has afforded a number of new 

 species, but has not added otherwise to the knowledge of these 

 faunas already acquired except as to the occurrence of the genus 

 Coscinocyatlms. 



The lull report is expected to be published before the close of the 

 present year (1906). 



The association of genera and species is given in the list below 

 (all the species are new) : —
