To the south of the Tsing-ling Range the above classification of the 
Sinian System no longer holds good. The Kisinling Limestone of 
western Hu-peh !—a massive grey limestone grading downwards into 
a slaty limestone and slates—has yielded in its upper part gigantic 
Orthoceras, or the pagoda stone, and other Ordovician fossils; and 
is therefore regarded as equivalent to the upper and the middle part 
of the Sinian in north-east China. Unconformably underlying the 
Kisinling Limestone, a glacial deposit, the Nantou Tillite, was found 
by Willis and Blackwelder at Nan-tou, near the north-western 
entrance of the I-chang Gorge (about long. 111° 10’ E., lat. 30° 45’ 
N.). Mr. V. K. Ting has verbally informed the writer that this 
interesting deposit extends towards the south-west for a considerable 
distance. The occurrence of Asaphus and Trinucleus to the south 
of Ning-kiang (about long. 106° E., lat. 32° 45’ N.) makes it highly 
probable that, there, the upper Sinian is exposed among other 
folded Paleozoic strata.” 
Further south, in eastern Yun-nan, the Cambro-Ordovician rocks ® 
present an entirely different facies to that of north-east China. 
Nevertheless, they contain the same fauna, at least throughout the 
Cambrian formation. According to Dr. Deprat, the Ordovician 
there consists of sandstones, shales, and marls, and the Cambrian 
consists of an upper group of argillaceo-arenaceous rocks and a lower 
group of compact grits with intercalated limestone. A local strati- 
graphical break appears to exist between the Ordovician and 
Cambrian. 
Loczy regards the limestone that occurs to the east of Pa-tang 
(about long. 99° E., lat. 30° N.), and its associated metamorphic 
strata, as a Sinian formation. Richthofen considered at one time 
or another three successive series of rocks as Sinian representatives 
in south-east China. They are :— | 
c. Matsu Limestone. A dark-grey siliceous limestone containing sandy 
and clayey slates, hornstones, and calcite-veins. Typical exposure 
is found in the Matsu-shan, on the northern side of the Poyang-hu. 
b. Lushan Slate. Grey-green, fine-grained slates with characteristic 
quartz-veins which are often auriferous; typically occur in the 
Lu-shan, north of the Poyang-hu. 
The Kauling Slate that occupies large areas in the provinces of 
Kiang-si and southern An-hwelis possibly identical with this series. 
a. Tahau Sandstone. Massive, quartzitic red sandstone forming the 
bulk of the Tahau-shan, south-east of Ta-tung, southern An-hwel. 
It should be emphatically pointed out that both Loczy and 
Richthofen are unable to preduce paleontological evidence for their
