THE 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. 1, 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. 
C1. Just below C2, same section; just above C4, same section; about 75 feet below C62, 
which occurs at a locality 3 miles east; about same horizon as Cro, different 
section; about 150 feet below C12, same section. 
Middle Cambrian: Lower shale member of the Kiu-lung group [Blackwelder, 19074, 
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, 1907a, Research 
in China.) 
Protospongia chloris Hyolithes cybele Anomocarella albion 
Obolus minimus A gnostus chinensis Anomocarella chinensis 
Obolus (Westonia) blackwelderi Dorypyge richthofeni Dolichometopus alceste 
Acrotreta pacifica Inouyia divi Dolichometopus deois 
Acrotreta shantungensis ? Lisania agonius Dolichometopus derceto 
Pelagiella chronus 
C2. Just above C1, same section; above C4, same section; about same horizon as C1o, 
different section. 
Middle Cambrian: Lower shale member of the Kiu-lung group [Blackwelder, 19072, 
pp. 37 and 4o (part of the third list of fossils), and fig. 10 (beds 4 and 5), p. 38], 
2 miles (3.2 km.) south of Yen-chuang, Sin-t’ai district, Shan-tung. C2 con- 
tains specimens from the central portion of the lower shale member—from the 
second ‘‘x”’ from the left side of the figure on page 38 to but not including the 
fourth “‘x”’ from the left. 
Protospongia chloris Dorypyge bispinosa Anomocarella biston

Acrotreta pacifica Lisania agonius Coosia ? daunus 
Hyolithes cybele Anomocare latelimbatum  Dolichometopus deois 
Orthotheca cyrene dryas Anomocarella albion Dolichometopus derceto 
Agnostus chinensis 
C3. About 100 feet above the horizon of C 60, different section; about 175 feet below the 
horizon of C8, different sections. 
Lower Cambrian: Lower part of the Man-t’o shale formation [Blackwelder, 19072, 
p. 28 (list of fossils at bottom of page), and fig. 8a (bed 20), p. 28], on the south- 
east slope of Hu-lu-shan, 2.5 miles (4 km.) southwest of Yen-chuang, Sin-t’ai 
district, Shan-tung.
