secondary rocks, the gravels are evidently subsequent in date to both, 

 and seem to have attained a considerable thickness on the higher 

 part of the ridges towards Kerokovi. 



Lignite, similar to that of Oropo *, occurs in a valley to the N.E. 

 of Limnse, but has not been worked. 



Interior of Euhoea. — The next localities to be noticed are those 

 within the interior of Euboea, viz. the Mandondi valley, lying on the 

 east of Mount Kandili, and opening into the iEgean Sea ; next the 

 Xero Khori valley, opening into the north channel of Euboea. In 

 the former both formations are evident ; the older or lower being 

 that in the neighbourhood of Agia Anna, and the more recent being 

 the softer series of marls, sands, and gravels lying in the lower part 

 of the basin towards Akmet Aga. Hills of serpentine almost enclose 

 them on the east. 



The Xero Khori hills seem to be exclusively of red marls, sands, 

 and gravels, closely resembling the Atalanta deposits. And, although 

 I examined several good sections in the ravines and water-courses, I 

 found only a few fragments of some fragile shell which appeared to 

 be a Helix. These deposits have a slight dip to the north. 



Gulf of Stylida. — The lesser ridges bordering the Gulf of Stylida 

 (Gulf of Zeitoum) were found to be composed of the same deposits, 

 particularly in the district of Molo, to the east of Thermopyle, where 

 they extend for several miles. T examined them as far as Boudou- 

 nitza, finding many freshwater fossils scattered through the deposits, 

 similar to those procured at Livonati. These beds attain a thick- 

 ness of 400 and 500 feet, and dip to the S.W. at an angle of 18° 

 from the shores of the Gulf and towards the higher mountains en- 

 closing them. 



On the opposite side of the Gulf (of Zeitoum) these deposits seem 

 to have been for the most part swept away, except at Ekinos, the 

 acropolis of which stands upon a tilted fragment of white calcareous 

 strata, that resembles the deposits of the lower lacustrine formation, 

 and of which it may be a fragment formerly thrown up by some 

 local movement. 



Gulf of Salonika. — The Gulf of Salonika now requires a few ob- 

 servations, as its two shores present low hills which, extending from 

 the base of the lofty Olympus on one side and from the Cassan- 

 drian mountains on the other, are also of freshwater origin and 

 correspond with the latest lacustrine series, wherever I had the 

 means of examining. They consist of the soft grey marls, sands, 

 and gravels so characteristic of the deposits of the later period of 

 the great ancient Levantine lake. 



Near Leftero Khori, about twelve miles to the south of the Var- 

 dar river, I found the deposits to contain impressions or casts of 

 Limncea and Paludina in great abundance.
