the north side of the Hermus, between the ridge of Demirji and the Catacecaumene. 

 On the south of Simaul (Sec. 6) it occupies the whole surface of the ridge, 

 which is there very low, and consists of thinly-laminated sandstone, containing 

 mica, and breaking into large slabs. It extends thence southward for about five 

 miles, where it is overlaid by a tertiary tufa. About eleven miles further south, 

 the laminated sandstone reappears on the banks of the Aineh-chai, dipping from 

 30° to 40° S. by W., and is covered unconformably by the horizontal tufa. The 

 accompanying section is well exposed in this deep ravine, the hills on each side of 

 which rise to the height of 600 or 700 feet. 



Section, 7 miles N.E. of Selendi. Lat. 38° 45', long, about 29°. (See also the description, p. 18.) 





Micaceous Sandstone. 

 a. Peperite. b. Trachytic conglomerate. c. White marly quartz pebbles. d. Peperite, with boulders. 



These sandstones appear at intervals on the sides of the river to the distance of 

 six miles below Selendi. They are nearly horizontal, and on the south side of the 

 Aineh-chai have a slight northerly dip, reposing against a low ridge of saccharine 

 marble, which ranges between that river and the Hermus. On the south of this 

 axis, the sandstones again occur, dipping with a southerly inclination towards the 

 Hermus ; and are overlaid by horizontal beds of tertiary fresh- water limestone. 

 The following section in descending order, is exposed about a mile north of the 

 Hermus : 



White marl of the tertiary formation 5 or 6 feet. 



Alternate beds of marl and sand 20 



Loose beds of sand and gravel, with pebbles of quartz-rock and schist. . 30 



The sandstones above described did not occur to us elsewhere in Western Asia 

 Minor. They appear to be devoid of fossils, but are clearly younger than the 

 schistose group, and older than the tertiary beds ; and we have therefore preferred, 

 on account of their comparative unimportance, to class them, for the present, 

 under the Cretaceous system, than to assign them a separate place.

 Nummulites, associated with greenish argillaceous and arenaceous shales, which
