GEOGRAPHIC RELATIONS OF TRIAS OF CALIFORNIA 781 
and about 3000 feet up above the mill, on the trail from Inde- 
pendence ever the Inyo range to Saline valley. The fossils 
submitted to the writer were badly crushed and distorted, owing 
to the partial metamorphism that the limestone has undergone, 
so that they were not in condition for description of genera and 
species, nor for identification with known species. But the 
septa permitted the identification of several genera of ammonites 
with considerable certainty ; none of them were higher than the 
ceratite stage, and some retained simple goniatitic septa, a com- 
bination which, in itself, would point to Lower Triassic age, even 
if all the genera were new. The genera determined were all 
ammonites, no others being recognizable. The list is given on 
page 780, showing the range and occurrence of these genera. 
In the above list it will be seen that most of the genera are 
confined to the Lower Trias, or Scythic series, of India, and that 
while most of them range through the Brahmanic and Jakutic 
stages, they nearly all reach their greatest development in the 
Brahmanic, and are rare outside of it. Thus it is probable that 
the Ceratite limestone* of Inyo county belongs to the Brahm- 
anic. Another bit of evidence is the occurrence of some undeter- 
mined ammonites not included in the above list, resembling 
Otoceras, which in Armenia occurs in the highest Permian and in 
the Himalayas in the lowest Trias, only a few feet above the 
highest Productus beds, the top of the Paleozoic. 
This fauna is wholly unlike anything in Europe, or indeed 
anywhere else outside of India, but it resembles that described 
from the Salt Range by Waagen,? and from the Himalayas of 
India, and Ussuri Bay by Diener.3 Some years ago it was 
pointed out by Mojsisovics in Arkische Triasfaunen that the 
Lower Trias of Idaho was closely related to that of the Arctic- 
Pacific region, although no certain comparison could be made. 
In the Californian fauna we have the best means of comparison 
«So-called, because of the prevailing ceratitic type of the ammonites.
