Occurrence. — Lagena Isevis is one of the most common of the Lagense. It is 

 found in all latitudes and at all depths. Its earliest recorded occurrence in a 

 fossil condition is in the Wenlock Limestone (Upper Silurian, Brady). It has 

 also been found in the Lower Lias of Yorkshire (Blake) ; in the Middle Lias of 

 France ; in the Jurassic of Switzerland (Kiibler) ; in the Neocomian (Bargate 

 Reds) of Surrey; in the Gault of Folkestone; in the Red Chalk of Speeton ; in 

 the Upper Chalk of Taplow, Ireland, and Maestricht ; in the London Clay ; in the 

 Calcaire Grossier of the Paris Basin, in the Oligocene of Blsass and Pietzpuhl ; in 

 the Miocene of Piedmont ; in the Pliocene of St. Erth, Belgium (Casterlian and 

 Scald isian), Garrucha (South Spain), and Piedmont. In the Coralline Crag 

 L. Isevis occurs in all the exposures examined, but rarely, and the specimens are 

 small.
