dip of the strata is apparently to the N.E., at an angle of 8° 

 or 10°. 



In examining minutely the deposits forming the Point of Kus- 

 tenjeh, I found that this rock terminates abruptly on the north and 

 south sides of the promontory, as if by a fault ; and it is overlaid by 

 deposits that seem to belong only to the red marls or superficial 

 series, e, although the lower bed, immediately reposing on c, contains 

 casts of a Cyrena ? similar to what are found in the upper portion of 

 the group d, fig. 3, where the beds and fossils indicate no such evi- 

 dence of having been aggregated by moving waters.

e 2 . Reddish marls, e,. Shelly sandstones, 7 feet thick. 

 c. Older Tertiary oolitic limestone, marine. 



On the older tertiary deposit, c, is a thinly stratified yellowish 

 sandstone, e 19 7 feet thick, and composed almost entirely of frag- 

 ments of shells and oolitic particles. In it are bands and masses of 

 casts of Cyrencel like those found in group d> figs. 3 & 5. 



This deposit, e v from containing the oolitic grains and these bi- 

 valves, seems to be composed of the debris of groups c and d, under 

 a sudden disturbance of the old lake, in which the rock c formed per- 

 haps an islet or shoal during its previous tranquil condition. 



The next bed, e 2 , is about 30 feet of red marl or clay, without any 

 indication of fossils or foreign fragments, and is a small portion of the 

 superficial marls, e, of the Steppe, which I shall have to refer to in 

 describing more particularly the evidence of the separation between 

 the marls d and e of fig. 3. 



This will perhaps be best done by giving a section (fig. 5) of a 

 part of the cliff at about half a mile S.W. of Kustenjeh, where a 

 fresh landslip or scaling showed me clearly the point of separation 

 between the two series of marls, marked by the denudation of a por- 

 tion of the lower group, as seen at a, and the subsequent filling up 

 of the irregularities by the upper red marl series. This separation is 

 difficult to identify where the upper series reposes upon a more 

 indurated stratum of the freshwater series, as frequently occurs.
