Occurrence. — Lagena clavata appears to have been found by the ' Challenger ' at 

 one station only, namely, that off Heard Island in the South Atlantic, at a depth 

 of 75 fathoms, in a bottom of black mud. Its geological range is extensive, 

 though not many occurrences have been recorded. It has been found in the 

 Upper Silurian (Brady) ; the Lias of Yorkshire (Blake) ; the Miocene of Vienna ; 

 and the Pliocene of Belgium, Garrucha (South Spain), and St. Brth. In the 

 Coralline Crag we have found it at Sutton only, zone f.
