496 HISTORY OF GEOLOGY AND PAL/EONTOLOGY. 



inapplicable as the designation ot a biological province, was 

 used by Mojsisovics for the new palaeontological zone of 

 Alpine Trias which he now interposed above the Karnic 

 division 



According to this new interpretation offered by Mojsisovics, 

 the " Karnic" division of Hallstatt limestone with Am. 

 Aonoides, etc., is the equivalent of the Dachstein limestone 

 and Main Dolomite above the Raibl strata in many parts of 

 the Alps; the "Juvavic" limestones follow, and their upper 

 limit is determined by the Rhaetic horizon. Mojsisovics also 

 removed the salt deposits, the Reichenhall strata, the Pots- 

 chen limestone, and the Partnach- dolomite from the Noric 

 division, so that there remained in this division only the 

 nodular limestones, with Halobia Lommeli and a very scanty 

 fauna. 



Bittner protested against the erection of a " Juvavic " 

 division, contributing a series of articles on the subject to 

 the publications of the Austrian Survey or issuing them 

 independently. The attitude assumed by Bittner was that 

 the name of "Noric Division" was in the first instance intro- 

 duced for the Hallstatt limestone strata with Am. Metternichi, 

 and ought to be retained for these limestones, although in the 

 light of the more recent researches it would have to be placed 

 above the Karnic division in the stratigraphical succession. 

 The controversy became more and more personal, and was all 

 the more unfortunate for the literature, as the adherents of 

 Mojsisovics and of Bittner used the term "Noric Division" 

 to signify quite different horizons of Upper Trias. Bittner 

 then proposed to apply the name of "Ladinian" to the divi- 

 sion below the Karnic and to comprehend in it the nodular 

 limestones, the Wengen-Cassian series, the Schlern dolomite, 

 Esino limestone, and Wetterstein limestone. Thus Bittner's 

 suggestion was to recognise in ascending order Ladinian, 

 Karnic, and Noric Divisions of Upper Trias. But Mojsisovics 

 quite recently, in 1898, agreed at the instance of Suess, Diener, 

 and Hoernes, to discard entirely the term " Noric " and let 

 the division fall, recognising only a Lower or Karnic Divi- 

 sion and an Upper or Juvavic Division of the East Alpine 

 Upper Trias. 



By the discovery of rich fossil localities in the Triassic 

 rocks of the Himalaya and the Salt Range, the pelagic Triassic 

 deposits of Eurasian areas began to be classified from a wider
