Shasta county that have the stratigraphic position of the Mus- 
chelkalk, and a few species of fossils not incompatible with that 
age; they are 7vachyceras? conf. whitneyt Gabb, Pseudomonotis 
sp., and Proarcestes sp., and some others not identified. The 
fossiliferous shales lie about 1500 feet below limestones of Karnic 
ages, with the fauna of the Subbullatus zone, and conformably 
with them. 
TIROLIC SERIES. 
Noric stage—For the Upper Trias the Tyrolean Alps have 
always furnished the types of marine development; the faunas 
of this series have been compiled and described by Mojsisovics 
in ‘‘Die Cephalopoden der Mediterranen Triasprovinz,” and 
“Das Gebirge um Hallstadt,” although the works of von Hauer, 
Klipstein, Laube, and others have contributed largely to our 
knowledge of the fossils. 
The Noric stage in its typical development is known only in 
the Alpine region, where it is divided into the Fassanic and the 
Longobardic substages; but a somewhat different facies occurs 
also in Japan,’ although the substages cannot be recognized. 
In North America, too, are found strata probably of Noric 
age, in British Columbia ;? in Nevada, where part of the Star 
Peak section belongs to the Noric;3 in California where its 
fauna and stratigraphy have been described by various authors.‘ 
The reference of the western American beds to the Noric hori- 
zon is based chiefly on the occurrence in them of several species 
ot Monotis and Halobia allied to Noric forms and to the identity 
of several of the American species with those from Japan.
