THIS CAMBRIAN FAUNAS. 15 



LOCALITIES (WITH LISTS OF GENERA AND SPECIES AT EACH). 



For convenience of reference and to avoid repetition, the following list 

 of localities, with the genera and species found in each, is inserted. The lists 

 published by Willis and Blackwelder [1907, vol. i, Pt. I] are composite lists 

 made up by writing the lists of fossils from several localities in one list in order 

 to give the fauna that in their judgment occurs at some one stratigraphic 

 horizon of the Cambrian. For the purposes of the future student who may 

 wish to study the geographic distribution of the various subfaunas and to 

 work out the limits of the formations containing them, the local lists are 

 essential and give all known data concerning localities from which fossils 

 described in this paper have been obtained. When not otherwise stated, the 

 collections were made by Dr. Eliot Blackwelder. 



CHINESE LOCALITIES.

 which occurs at a locality 3 miles east; about same horizon as Cio, different 

 section; about 150 feet below C 12, same section.

 pp. 37 and 40 (part of the third list of fossils), and fig. 10 (bed 4), p. 38], 2 miles 

 (3.2 km.) south of Yen-chuang, Sin-t'ai district, Shan-tung. (At the second 

 "x" from left side of section given on page 38 of Blackwelder, 1907(7, Research
