FAUNA OF TIIK PROVINCE OF nil' MEDITERRANEAN 109 



Tin' mixed faunas <>t' the Adneth ami Rierlati beds, and of the gray lias 

 limestones ami Fleckeninergel, have been described by Giimbel, 1 l>\ Dionys 

 ami by G th verj interesting remarks upon the similar faunas 



elsewhere. The BrsI author regards th-- faunas of the Adneth ami Hierlatz 

 limestones a- having species representing nol only the various faunas of the 

 I -. but also th'' faunas of the Middle ami even Upper Liaa Oppel <'<m- 

 sidered th.- Qierlatz beds a- the equivalent of tin- Obtusus, Oxynotus, and Ran- 

 ker, who hi- examined this locality in detail, thinks, if ii is 

 compared with an\ single fauna, that we Bhould have t<> Belec( that of the Oxy- 

 notus bed He however falls attention to the occurrence of l- - . obiiuum and 

 ' 'aium in tin- Bame horizon, thus demonstrating the mixed chara< I 



5l ir regards it a- possible that th.' different beds of the Lower 

 lay, l>\ further investigation, be defined in the Adneth anil Bierlatz beds. 

 This conclusion, however, rests upon theoretical considerations, and not upon 

 actual observations, and this author observes, "doss in den Alpen einzelne arten 

 der Lias fauna hoher oder defer hinauf und herabreichen als in den ausser- 

 alpinischen Schichten beobachtel wurde, . . . nnd . . . wahrend der Liaszeil 

 innerhalb der Alpeng ;i" weniger streng geschiedene und minder man- 



nichfaltige Gliederung wirklich vorhanden ist 



Both Stur and Giimbel distinguish only three faunas in tin' Lower Lias of 

 th.- Kammerkahr Alps: I. A yellowish limestone with a species similar to 

 Johutom. '_'. An intensely red limestone with Amm. tpiratissiimit of rlauer, /

 Bucklandi bed was not distinguishable according to Giimbel. 3. Above this, 

 thinner layers with Amm. ra\ mthus, detuinodtu, and a form similar 



Giimbel states that the Adneth or 'lark red limestones, the 1 1 

 ui'l the gray limestonei G I ibens are equivalent to one 



another, and thai each contains a mixture of Bpecies from Lower, Middle, and 

 Dpp L 



M distinguish a Planorbis, an Angulntus, a Bucklandi, 



I iberculatus, and an Obtusus bed in the Osterhornes mountains, but 

 consider the Angulatus bed as the equivalenl of the Enzesfeld limestones, 

 and the Obtusus l"''l as the equivalenl of the Adneth limestones. The fauna 

 found by them did not, however, bo far as published, appear to justify this
