XV.— ON THE IDENTIFICATION OF CERTAIN LOCALI- 

 TIES MENTIONED IN MY PAPER ON THE DIA- 

 MONDS OF INDIA, BY V. BALL, m.a., f.g.s. 



[Read, February 21st, 1881.] 



Since my return to India I have been enabled by having access 

 to several books and maps to fix the position of some of the 

 oldest diamond mines whose identification has been a puzzle to 

 previous writers. I shall not give all the details here, but since 

 this Society was the medium by which my paper (vide these Pro- 

 ceedings, Vol. II., N.S., p. 551), was published, I think it right that I 

 should hasten to make what amende 1 can for having given cur- 

 rency, on the authority of other writers, to views which I am now 

 compelled to withdraw. 



Raolconda. 



This locality has been a great puzzle to most writers in 

 consequence of their trying to identify it by means of 

 Tavernier's statement that it was five days journey from Gol- 

 conda, and eight or nine from Visapour (the modern Bijapour), 

 Elsewhere, however, he gives a list of the stages — nine in all — 

 between it and Golconda, the sum of the distances being, I com- 

 pute, equal to 189 miles. 1 am, therefore, compelled to believe 

 thg,t in Tavernier's first statement the days' journeys were trans- 

 posed, and that it should be read eight or nine from Golconda, 

 and five from Visapour. With these new indices of position we 

 at once find a town on the map bearing the name Rawduconda, 

 in Lat. 15° 41', and Long. 76° 50'. 



Unfortunately the geology of this locality is not at present 

 known, but metamorphic rocks have been observed to occur at 

 no great distances both to the north and south of it. It is 

 possible that there may be an outlier of the Karnul rocks there. 

 I have not yet succeeded in fijidmg any recent account of dia- 

 monds being known to occur there. 



Gani or Coulour. 



This locality, regarding which I have given a quotation from 



Tavernier, was almost certainly identical with Purtial, in Lat. 



16° 39', Long. 80" 27', although Capt. Burton located it on the 



Bhima river. According to Tavernier, whose stages can to
