Report of the Curator, Museum of Economic Geology. 



Geological and Miner alogical. — We have received, from Dr. Kelaart of 

 Ceylon, two specimens of Granite, one of which is a garnet granite, the 

 Garnets being of the Essonite or Cinnamon- stone variety. It also contains 

 some minute semi-crystallised dull black-green grains which may be horn- 

 blende or tin ore, but the only assay I could take from such a small speci- 

 men leaves it uncertain if the reduced metal was iron or tin. 



Economic Geology. — Captain Sherwill has sent us from Singrowlee in 

 Eewah — 



Native Copper from near the fort of Burdee on the Soane Eiver ; 



Copper Pyrites ; 



A fine red Gossan of Copper from that quarter ; 



Gold Dust Sand from Jushpore ; 



Coal of a very fine appearance ; 



Galena, Iron ore, Iron Pyrites, Limestone and Zinc Blende. 



The first and last articles of this list are the most remarkable ; the Cop- 

 per for its purity (and Captain Sherwill's informant says there is plenty of 

 it !) and the zinc ore as being a novelty in Lower India,^ and both may be 



* Perhaps the Rh. mitbatus, nobis, J. A. S. XIII, 483, may prove to be no 

 other than this, though the ear-conch (in the dried specimens) would seem to be 

 somewhat larger ; and the additional Indian species now ascertained to those above 

 noticed, are Rh. affinis(?), Horsfield, from Ceylon, vide p. 346, ante, — Rh. 

 Rouxi, Teunminck, — and Rh. Pearsonii, Horsfield, ' Catalogue of the specimens 

 of Mammalia in the Hon'ble Company's Museum' in London. — Of the affined 

 genus Hipposideros the ascertained Indian species are those mentioned in my 

 last Report, p. 346, ante) -, and the curious genus C^elops, nobis, /. A. S. XVII, 

 251, is evidently much affined to Mormoops of Leach, figured in Lin. Trans. 

 XIII, t. 7, p. 77, now ascertained to inhabit Cuba, — and to Centurio, Gray, 

 (' Zoology of the Voyage of the Sulphur'), uncertain whether from Amboyna or from 

 S. America : but it has not the singularly elevated cranium of the former genus, 

 nor is the ear-conch bifid to the front, as in both the others. The tail and inter- 

 femoral membrane resemble those of Centurio ; and the middle finger has three 

 phalanges, whereas that of Centurio has four (as generally in the Phyllostoma 

 group). f Vide p. 347, ante. 



X The only Indian Ores of Zinc which we have till now are from Jawar in 

 Ajmeer (See Journal Vol. XIX, p. 212) presented by Captain Brooke.
