CLASSIFICATION OF MARINE TRIAS 393 
up by Mojsisovics in ‘Die Cephalopoden der Mediterranen 
Triasprovinz,”* and later F. von Hauer has described many 
species from the Muschelkalk of Bosnia,? from which this sub- 
stage takes its name. 
In the Himalayas the Balatonic substage is represented by 
the zone of Stbirites prahlada, and the Bosnic division by the zone 
of Ptychites rugifer. In this horizon there are three species com- 
mon to the Mediterranean and the Indian regions, Orthoceras 
conf. campantle Mojsisovics, Proarcestes balfouri Oppel, and Sturia 
sansovini Mojsisovics, and other closely related.3 Certain beds 
of the Salt Range also belong here, but their fauna is too poor 
and too little known to be comparable. 
In the Asiatic region the Anisic stage is represented on the 
shores of the Sea of Marmora;‘ further on the Island of Russkij > 
near Wladiwostoc, Siberia; near the mouth of the Olenek River;° 
also, according to Dr. Diener, near the mouth of the Lena. 
The Posidonomya limestone and the Daonella limestone ot 
Spitzbergen, according to Mojsisovics, represent the Dinaric 
series, the former probably the Hydaspic, and the latter proba- 
bly the Anisic stage. 
F. B. Meek? has described from Star Peak, Nevada, a num- 
ber of Triassic species, part of which, according to Pro- 
fessor A. Hyatt,® belong to the Muschelkalk horizon. Waagen 
and Diener? erroneously make Hyatt cite Muschelkalk from 
Plumas county, California, but Hyatt’s remarks referred only to 
Nevada. There are, however, in California strata probably of
