Alps, and its near relative may belong to the same horizon in a 
different geographic province. 
In Shasta county, California, the Pitt formation consists of a 
series of siliceous shales probably in part of Lower Triassic age, 
but no fossils have yet been found in that part of the series. 
Outside the Arctic-Pacific region the Jakutic stage is repre- 
sented in the Alpine province by the Werfen beds, zone of 
Tivolites cassianus; this fauna has long been taken as the type of 
marine Lower Trias, until the rich discoveries in India have 
shown the comparative poverty of the Alpine fauna. In the 
Mediterranean region are known in this stage only twenty-five 
Cephalopoda against two hundred and twelve in the Asiatic region. 
DINARIC SERIES. 
Flydaspic stage—Faunas of the Hydaspic stage are known 
with certainty only in the upper Ceratite limestone of the Salt 
Range,’ where forty-one species have been described, consisting 
chiefly of Dinarites, Ceratites, Prionites, Danubites, Celtites, Acrochor- 
adiceras, Stephanites, Sibirites, Goniodiscus, Meckoceras, Lecanites. 
Thirty-five of these species belong to the Zvachyostraca, and only 
six to the Lezostraca, a marked contrast to the distribution in the 
Scythic series. 
The Posidonomya limestone of Spitzbergen may belong here, 
if one may judge from the stage of development of the ammon- 
ites,3 as may also the limestone of Chitichun in Thibet, according 
to Dr. Diener.‘ 
Anisic stage —The type of the Anisic stage is found in the 
Muschelkalk of the Mediterranean region, where it is divided 
into a lower substage, Balatonic, zone of Ceratites binodosus, and 
on upper, Bosnic, zone of C. 7vinodosus. These faunas have been 
described in many works, but all the species have been summed
