of white marls and limestones would seem to have suggested to 

 Russell the adoption of the term * Idalian ' to define them, great 

 rounded hills occur in a succession of undulations extending from 

 the neighbourhood of Margi on the west to Athienou on the east, 

 parallel with the Idalia, or Yalias Eiver. 



At Athienou these beds pass into a massive granular limestone, 

 of finer quality and less density, which yields a very useful material 

 known as Athienou Stone, easily cut and much used in the manufacture 

 of a number of different utensils for domestic purposes. 



Near Psathi, compact and massive beds of fine-grained gypsum 

 of straight cleavage are worked for the extraction of paving slabs 

 known as ' marmoras.' Their cleavage is very true and even, and 

 their texture is such that they can be cut with a saw and smoothed 

 with a plane. These beds also contain a quantity of native sulphur, 

 in veins and nodules. 



Ochres are found principally at Mavrovouni near Larnaca, and 

 also near Limassol, where they are worked for terra umbra, a con- 

 siderable export trade in which is carried on. 



Fossil remains are not numerous, except among the white, compact, 

 chalky marls, which contain a few shells and Echinoderms similar to 

 those to be met with in Malta and Sicily. Some of the limestones, 

 however, are largely made up of the minute shells of Foraminifera, 

 and resemble the Globigerina limestones of Malta. 



With regard to thickness, it is not easy to give an estimate 

 because of the frequent flexures, but they probably range from 

 1,500 to 2,000 feet. 



5. TTie Igneous Bocks of the Central Mountains. — These rocks form 

 a tract of mountainous ground which extends for a distance of about 

 60 miles, with an average breadth of 17 or 18 miles. It includes 

 the mountain groups known as the Machera on the east, the Adelphi 

 and Troodos Eanges in the centre, and the Tillyria Mountains on 

 the west ; it extends from a point a few miles to the north-west of 

 Larnaca to the shores of Morphou and Krysokhou Bays in a con- 

 tinuous mass. North-east of Larnaca is an inlier in the neighbour- 

 hood of Stroullos and Mavrovouni, and another smaller isolated 

 outcrop occurs near Petrophani to the westward of Athienou on the 

 main road, and about half-way between Nicosia and Larnaca. 



In the district of Paplios and in the extreme western end of the 

 island are other outcrops, such as that near Fontana Amorosa, near 

 Ag. Epiphanios, Cape Acamas ; at Ag. Ismenas, Ag. Yeorghi, Cathika, 

 and Akourso. 



The central mountains are the highest ground in the island, and 

 include the great dome-shaped mass of Troodos, the summit of 

 which, ' Chionistra,' is 6,406 feet above the sea, and the Adelphi 

 Range, which culminates in a height of 5,305 feet. 



The areas occupied by these rocks are coloured brown on the map. 



The ophitic rocks Gaudry calls ophitones and spilites. These 

 terms are now obsolete, but were formerly applied to the rocks 

 which are now known as diabase and dolerite ; he also describes 

 a spherulitic rock, which seems to correspond with that now known
