COLE I ON THE RED CHALK. 
39 
Cidaris sceptrifera, and peculiar stems, probably of sponges 
or fucoids, resembling a small branch of a tree. At Warter, 
the upper red and grey beds yield numerous small Tere- 
bratulae, mostly T. semiglobosa, one very minute, known as 
Terebratulina gracilis ; also spines of Echini, and two forms 
of Rhynchonella, Sulcata and Martini ; and the hard red 
band at the base is full of Belemnites, as is the case also at 
Millington springs. On the whole, the red chalk is, com- 
paratively, far richer in fossils than the white.
