meters in this locality, but its base is covered. Above these marls lie gray- 

 bluish marls with large cephalopods ; the thickness of this horizon which 

 we designate as Number II, is 2.5 meters. On top of these marls we find 

 gray limestones with numerous cephalopods, bivalves and gastropods ; the 

 thickness of this horizon, which we call Number III, is about 5 to 6 meters, 

 its upper limit being unknown. According to Dr. Haarmann the beds 

 show a strike of N50-60E and a dip of approximately 10NW. 1 



The whole outcrop has thus only a thickness of about 10 meters, but 

 nevertheless we find two different horizons, as will be shown in the 

 following. Among the fossils collected in this locality I have been able to 

 distinguish twenty-one different species which are distributed in the three 

 horizons in the following manner : 

 Horizon I. 



Metoecoceras aff. Whitei Hyatt 



Metoecoceras n. sp. 



Exogyra Haarmanni n. sp. 



Exogyra cfr. olisiponensis Sharpe 



Hemiaster sp. 

 Horizon II. 



Mammites mohovanensis n. sp. 



Pseudaspidoceras aff. Footeanum Petrascheck 



Pseudaspidoceras aff. pedroanum White 



Vascoceras aff. Adonense Choffat 



Fagesia Haarmanni n. sp. 



Fagesia Pervinquieri n. sp. 

 Horizon III. 



Vascoceras Angermanni n. sp. 



Vascoceras ex. aff. Gamai Choffat 



Vascoceras (?) sp. 



Vascoceras mohovanense n. sp. 



Neoptychites aff. xetriformis Pervinquiere 



Hoplitoides aff. mirabilis Pervinquiere 



Inoceramus labiatus Schlotheim 



Avicula Aguilerae n. sp. 



Trigonia sp. 



Crassatella sp. 



Tylostoma aff. ovatum Sharpe 



To show the stratigraphic importance of the different species we shall 

 have to compare them with related forms. 



iAccording to a sketch of Dr. Angermann the strike of the beds i3 N-S and the 

 dip 10 degrees W.
