from I In- Inland of Malta. 57 



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 vertebrae 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.

No. 3. The clay bed, has a dark blue, drab, or a light gray 

 colour, and is much charged with iron. In it are found crystals 

 of gypsum, and occasionally nodules of sulphur. It varies in 

 thickness from 30 to 60 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.
