332 THE PORTLAND OOLITE PERIOD. CHAP. 



Ammonites superstes. Phil. n. s. K. C. Minety. 



triplex. Sow. K. C., P. K. Swindon. 

 Belemnites excentricus. Blain. K. C. Shotover. 



explanatus. Phil. K. C. Shotover, Waterstoke. 



hastatus. Blain. K.C. Aylesbury. 



Owenii. Blain. K.C. Shotover. 

 Trigonellites latus. Park. K. C. Baldon, Heddington. 



The ammonites in this list (by no means including all the species) 

 require much additional study before they can be regarded as fully 

 determined. The species or group called A. biplex is unsatisfactory, 

 and the gigantic sorts of Aylesbury Swindon, and Portland are 

 not clearly discriminated. The upper part of the Kimmeridge and 

 the lower part of the Portland beds have species in common.
