fact, corresponding to the occurrence of equally large individuals of this variety at very 

 great depths (1080 fathoms) in the tropical Atlantic (lat. 2° 20' N., long. 28° 44' VV.). 



Professor Reuss has it fossil from the Chalk of Maestricht and of Lemberg, from the 

 Oligocene Septarium-clay of Pietzpuhl, the Salt-clay of Wieliczka, and the Crag of 

 Antwerp (' Monogr. Lagen.,' p. 318) ; and in other Tertiary deposits it is not uncommon. 



The Crag specimens are generally above the average size ; and the number of examples 

 in the Cardita senilis bed and the bed with Cyprina Islandica is considerable.
