Northeast occurs then limestone in the vicinity of Tanjung Bunga 

 or Kopondai, the well-known Cape Flores, to which the island owes 

 its name. At a distance of 300 m. eastward from the cape men- 

 tioned, G. A. J. VAN DER Sandf, (Uscovercd a grotto with stalactites. 

 And at last, according to A. J. L. Couvreur, coral limestone is found 

 to the North of Larantnka from Panté Lela to Panté Beli Beting, 

 especially between the village of Tjabao and Hi Labao. 



The entire remaining part is covered with volcanic material the 

 monotonousness of which is only interrupted by the numerous partly 

 still active volcanoes. In the North westward from Maumeri rises 

 the volcanic ruin of Kiman Buleng (1446 m.). Gunung Dobo or 

 Iliang (900 m.) situated behind Geliting but nearer to the South- 

 coast is on the contrary still active. 



Most known, though likewise not sufficiently examined, are the 

 volcanoes situated on the East-coast of Flores. For times immemorial 

 Ilimandiri (1570 m.) has not given any sign of activity. The rock 

 of which it is composed is chiefly augite-andesite.^) Kabalelo (1075 m.) 

 situated eastward is an old volcanic ruin. ^) Westward from it Leworoh 

 is situated where on the 16^^ of March 1881 an explosion-crater 

 formed itself. ■) The largest, highest and most active volcano however 

 in this territory is Lobetobi, consisting of two cones Lakilaki 2170 m. 

 high and Parampuan 2263 m. high. 



G. F. Tydeman perceived about 37 km. westward from Lobetobi 

 a high volcanic cone; most likely Dara Woër is meant b}' it. ^) 



As appears from the above, there is in Flores no room for 

 praeterliary sediments and eruptive rocks. Repeatedly however the 

 existence of such like rocks in the form of boulders was hinted at. 

 Near the bay of Bari I found in 1888 quartz-porphyry, clay slate 

 and quartzite. ^) I may now add to this the communication that in 

 the river Reo amphibole-granite and diabase occurs, the hornblende 

 of which has changed into chlorite. More eastward in the territory
