All these are also recorded from the various members of the 

 Upper Gault of Folkestone. The most abundant forms are : — 

 Inoceramus tenuis, Schloenbachia varicosa, Terebratula biplicata, 

 Cardita tenuicostata, and Lamna appendiculata ; and the general 

 aspect of the fauna suggests a correlation with the upper part of the 

 zone of Schloenbacliia varicosa, Bed IX of Mr. Hilton Price's Folke- 

 stone Gault. \ The species marked with an asterisk are common to the 

 two beds. Most of the other species have somewhat wide ranges, 

 but the occurrence of Terebratulina triangularis is notable. This 

 fossil abounds in the Cambridge Greensand, and is not generally 

 supposed to extend much below that horizon ; its occurrence in the 

 Hard Band is, however, undoubted, and several specimens of it 

 have been met with. The record of ScliloenbacJiia rostrata, unfor- 

 tunately, is not so satisfactory ; but large pieces of an ammonite, 

 which may be Schl. rostrata, are very abundant in the clay just above 

 the Hard Band. 



From this new palseontological evidence, and from the fact that 

 the fossils mentioned are all obtained some 40 feet below the upper 

 surface of the Gault, I conclude that the whole of the Upper Gault 

 of Cambridge was not used up in the making of the Cambridge 

 Greensand, but that a thickness of at least 45 feet of it remains at
