198 SPOLIA ZEYLANICA. 



5. Minerals neiv or rare in Ceylon. — Of the following 

 minerals, some were omitted from the list of Ceylon minerals 

 given in Spolia Zeylanica^ part IX., 1905 ; the remainder have 

 been discovered since. 



A. — Minerals new lo Ceyluii. 



Galena. — Occurs in small cubes and rolled fragments in nambu 

 from the Getaheta-oya at Murutangala in Getaheta. Reported 

 from other localities. 



Cassiterite. — Occurs as small black pebbles in nambu at 

 Niriella and Noragala, and in larger fragments at Kuruwita. 



Selenite. — Massive at Kukulawalakanda, Ratmale, Pasdun 

 Korale, intergrown with pyrite between veins of graphite [James 

 Parsons] ; also in crystals in fossiliferous marine clays, Matti-aru, 

 Kuchaveli, north of Tricomalee. 



Monazite. — Occurs in waxy yellow well-worn grains in sands 

 of the Getaheta-oya and other rivers near Avisawella ; but was 

 first detected by Dr. J. W. Evans in specimens of heavy sands from 

 the Niriella-ganga sent to the Imperial Institute by the Mineral- 

 ogical Survey. 



Orangite. — It has been pointed out that the " thorite " of 

 Ceylon really belongs to the variety known as orangite, dis- 

 tinguished by slightly greater specific gravity and orange colour. 

 The apparently orthorhombic form of the mineral however 

 remains unexplained.' The crystals are not good enough to give 

 satisfactory measurements, and too much altered internally for 

 optical examination. 



Platinum. — Occurs very sparingly, associated with gold in 

 river sands at Dombagomuwa and Karawita, Sabaragamuwa. 

 [James Parsons]. 



The following minerals have been reported, but on present 

 evidence cannot be accepted as found in Ceylon. The sulphides 

 are quite likely to be found: — Ginnabar, Stihnite^ Realgars 

 Epsomite, Olivine [see Bertha Vukits Centralblatt fiir. Min. etc., 

 1904, No. 23, p. 715]. Minerals sent by the Mineralogical Survey 

 to the Imperial Institute were provisionally identified as 

 Annerodite and ^schynite or Polycrase. 



B. — Mineral names omitted in the List. 



Molybdenite. — Recorded by Dr. Gygax, and in Gustav Leonhard's 

 '* Handworterbuch der topographischen Mineralogie," 1843. I 

 re-discovered this mineral this year in the Kegalla District, 

 where it occurs [at HettimuUa] in a vein of pegmatite cutting the 

 srranulites.
