General Stratigraphic and Geographic Position of the Cambrian Faunas of China Continued. 



*Occurs in 107, Middle Cambrian, Alabama, and is introduced for comparison. 

 fOccurs in 91, Middle Cambrian, Alabama, and is introduced for comparison. 



NOTE. The columns "Near Sin-t'ai-hien," "Near \Vu-t'ai-hien," and "Near Ting-hiang-hien" 

 are omitted in this page, as the species recorded in the first column were not collected in those localities. 



RELATIONS OF THE FAUNA TO TYPICAL STRATIGRAPHIC SECTION. 



In order to avoid the repetition of the lists of species from the various 

 localities, a list of localities with the species occurring in each is given [pp. 

 15-28]. In the following Stratigraphic sections the numbers designating the 

 localities will be inserted so that the student may, if he desires to learn 

 just which species occur in a given locality and position in the section, 

 refer to the list under the locality number. In some instances it is not 

 practicable from the known Stratigraphic and paleontologic data to assign 

 the exact horizon. In such cases an interrogation mark is placed before 

 the locality number.
