A New Ammonite Fauna of the Lower Turanian of Mexico 197 



Syria and Palestine: Of this characteristic fauna nothing seems to be 

 known in other parts of the Mediterranean. In Syria and Palestine, 

 Turonian beds are scarcely known. Notling cites from there a cephalopod 

 similar to Prionotropis Woolgari, and Diener cites a Mammites nodosoides. 

 This does not prove that .the Salmurian in its north African facies does not 

 exist there, because only a few years ago we did not know any more about 

 the Turonian of Egypt, until Eck published his first lists of cephalopods. 



Southern France: It seems that on the European border of the Med- 

 iterranean the north African facies of the Salmurian with its character- 

 istic fauna of cephalopods is yet unknown. In France the same horizon 

 has quite a different fauna. In Provence there are, according to Gros- 

 souvre, 1 beds with: Mammites nodosoides, M. conciliatus and Pseudo- 

 tissotia Douvillei, but at least the first two of these species are nearly 

 universally distributed types. Pervinquiere adds to this list Fagesia 

 Boucheroni Coquand. In Aquitania the following cephalopods have been 

 found : Pseudaspidoceras salmuriense, Fagesia superstes ?, Fagesia Bou- 

 cheroni Coquand, Fagesia tevesthensis, and Neoptychites cephalotus. 

 Thus this fauna contains quite a good number of the Salmurian fauna of 

 the Mediterranean, although in the case of Fagesia and Neoptychites it 

 seems that only very rare specimens have b.een found. 



Saxony and Bohemia: The fauna of tli- Salmurian in Saxony and 

 Bohemia contains a still smaller number of elements which might belong 

 to the Mediterranean facies. Fritsch- describes from there as Mammites 

 conciliatus Stoliczka a form which certainly belongs to this group, although 

 as Kossmat already has noted, the species is different. The same author 

 cites Acanthoceras Neptuni. Laube and Bruder 3 figure Mammites nodo- 

 soides and other species of this genus, as well as Puzosia Austeni. Petra- 

 scheck* cites Mammites Footeanus Stoliczka, Mammites cfr. crassitesta 

 Stoliczka, Barroisiceras ( ?) Fleuriausianum d'Orbigny, Acanthoceras cfr. 

 Choffati Kossmat; all forms of groups which in part occur around the 

 Mediterranean and in part in India. 



Northern Europe: The faunas of the Salmurian of northern France 

 and nothern Germany show much less similarity with the Mediterranean 

 facies. They contain only ammonites belonging to groups of a universal 

 distribution, like Mammites nodosoides, Barroisiceras (?) Fleuriausianum, 

 Acanthoceras Neptuni, Pachydiscus peramplus, Puzosia Austeni, etc. Of 

 course, we have to take into consideration that neither in northern Ger-
