VII.—Corats rrom tHe Rep CHaxxk or Hunstanton, NorFOLK. 
The Red Chalk of Hunstanton contains several forms of Madreporaria. The small 
fauna has this peculiarity—its species belong to the group of the Fungide without excep- 
tion. The specimens are small, usually much worn at the calicular end, and are readily dis- 
tinguished by their mammiliform appearance and white colour. There are no compound 
Fungide in the Red Rock, but only such small simple forms as would now characterise the 
presence of physical conditions unfavorable for Coral life. The recent simple Fungide are 
found at all depths. Vast numbers of fossil specimens are to be collected in the 
Lower Chalk of Gosau, a few exist in the Upper Greensand and in the Neocomian forma- 
tions. In the existing Coral-fauna no simple Fwagide are found in the West Indian 
Seas, whilst the Red Sea, Pacific, and Indian Oceans, abound with them. It is probable 
that peculiar conditions are necessary for their development.
