246 COL. T. ENGLISH ON THE EOCENE AND [Aug. 1904, 



Xummulitic deposits have been found in Samothrake (5, p. 9), 

 along the whole length of the Eocene coast-line in Thrace (3, passim). 

 at Yernitza, and at Teke, near Keshan (on the north side of the Gulf 

 of Xeros), and from Bourn ar Oren to Mount Elias, along the northern 

 shore of the Sea of Marmora. They appear also on the southern 

 shore of that sea at Kara Dere, west of Gueredje, and nearly opposite 

 to Gallipoli (4, p. IS), and at Korou, south of Lampsaki. 1 The 

 foraminifera and other fossils collected from the Nummulitic 

 (Lutetian) Limestones of Yernitza and Mount Elias are described in 

 Appendices II & III (pp. 288, 292). 



Coralline limestones, generally harder than the Xummulitic 

 deposits, are frequently interstratified with them, as at Yernitza ; 

 and also occur separately at Saraiyik, about 4 miles east of Chanak 

 in the Dardanelles, and at numerous localities in Thrace. 



Prof. L. de Launay (6, p. 244 & map), following TchihatchefT (7. 

 vol. iii, pp. 172 et seqq.), but with some reserve, shows in his 

 geological map, as unfossiliferous Eocene, a great belt of country 

 some 50 miles wide, bounded on the north by the Marmora shore 

 from the Gulf of Artaki to Guemlek, and sweeping round to the 

 south-west until it meets the sea, from Adramyti nearly to Smyrna. 



III. Uppermost Eocene and Oligocene. 



Immediately overlying the Xummulitic rocks is a succession, 

 about 3000 feet thick, of lacustrine sandstones, clays, and shales. 

 interstratified with volcanic rocks and containing coal-seams. 

 These strata represent the uppermost Eocene and the Oligocene, 

 and the coal-seams belong to the latter formation. They are 

 widespread in Southern Thrace, and are cut off to the eastward 

 by the falling-in of the Marmora sea-bed. They extend along 

 the Gallipoli Peninsula to the islands of Imbros and Lemnos, and 

 possibly farther southward to Psara and Eubcea. 



In the paper which I had the honour of reading before this 

 Society in December 1901 (9, pp. 153-55), I described the coal- 

 basin near Keshan, the only one the limits of which had then 

 been partly traced. Since that time, the existence of the same 

 principal seam has been proved at a number of points, notably at 

 Masatly and Harmanly, about 17 miles north of Keshan. The 

 Keshan coal-basin has also been traced eastward for about 12 miles 

 to a point south of Malgara, and there is every reason to believe 

 that it extends yet farther eastward in the direction of Rodosto, 

 and westward across the Maritza River. 



The evidence of its age is as follows : — A lower jaw and teeth, 

 included in the coal itself, and now at the British Museum, were 

 discovered at Masatly, and have been identified as Anthracotherium, 

 nearly related to A. minus. 



There are innumerable impressions of leaves distributed through 

 the sandstones and clays, yet in only one case have they been found 

 in a recognizable condition. Prof. Toula. in 1895, found plant-
