In the first paper of this series, which we had the honour to read 

 before this Society in June, 1908, we gave a short account of the 

 nature, position, and extent of the deposits, both recent and fossil, 

 which we had searched, particularly with reference to the newly 

 discovered Eotalian genus Cyclolocidina. A reference to that 

 paper will demonstrate to the Ehizopodist of what extraordinarily 

 diversified materials the shore-sands of Selsey Bill are composed, 

 and it will cease to be surprising under the circumstances that so 

 wide a range of Foraminifera should be discoverable in them, 

 both as regards number of genera and of species, and as regards 

 periods of geological time. 



In the foremost place, of course, we find the ordinary shallow- 

 water littoral species in their usual profusion when sought for 

 under favourable conditions, the extremely flat and far-reaching 



* The first of this series of papers was published in the Society's Journal, 

 1908, pp. 529-543, under the title of " On Cyclolocidina, a New Generic Type of the 

 Foraminifera ; with a Preliminary Study of the Foraminiferous Deposits and 

 Shore-sands of Selsey Bill."
