No. 2. The yellow sand, is sometimes slightly indurated, and 
has an abundance of greenish-black grains intermixed with it. 
In some places it abounds with Foraminifera. Enormous numbers 
of Lenticulites complanatus, Defr., the flat side of the shell cor- 
responding with the bedding of the rock, occur in some localities, 
as in the cliffs of Ramala Bay, Gozo, and in many places in 
Malta. Intercalated with these Nummulites are banks of 
oysters, the teeth and vertebre of fishes, especially those of the 
great shark, Carcharodon megalodon, with the bones of Cetacea. 
The greatest number of Echinoderms are likewise found in this 
bed. It varies in thickness from 10 to 40 feet.

It is the retentive water-bearing 
stratum of the islands, and all the water falling upon the upper 
beds percolates through them, and bursts out in springs along 
their line of junction with the clay. Casts of shells and frag- 
ments of bones are very abundant in it; but Echinoderms are 
comparatively rare.
