320 FORAMINIEERA OF THE CRAG. 



together witli the somewhat peculiar perforation of the shell-wall on the lower 

 surface. 



Occurrence. — Living at depths of from GO to 290 fathoms in the North Atlantic, 

 Mediterranean, and Adriatic, and at one spot off the west coast of Patagonia. It 

 is a known fossil in the Loudon Clay, the Crag of Suffolk, the Pliocene of Italy, 

 and the Post-Tertiary of Norway. 



Amongst Messrs. Crosskey and Robertson's gatherings from the Glacial Clay 

 (Post-Tertiary) of the coast of Norway, examples precisely similar to those found 

 in the Crag occur. It is a matter of some interest in connection with these 

 fossils that the genus Pulvinnliva, though well represented over a large portion of 

 the area of the British seas, is almost unknown as a recent Foraminifer on our 

 eastern coast, neither does it occur amongst the sub-fossilised mici'ozoa of 

 the Fens. 



The large specimens — such as our figures are taken from — are in Mr. Searles 

 "Wood's Collection from Sutton ; smaller examples were found in the Polyzoan 

 debris from Sudbourne.
