held and the intrusive character fully recognised. See Fermor 

 (Mem., Geol. Surv., Ind., XXXVIII, 238, 1909), and cf. Balagliat 

 and Bellary gneiss. 



Burmite. — Name suggested by Dr. 0. Helm and used first by F. Noetling 

 (Rec, Geol. Surv., Ind., XXVI, 31, 1893) for the amber-like 

 resin found in Upper Burma. It differs in chemical composition 

 and physical characters from amber. (Helm, Rec. Geol. Surv., 

 hid., XXV, 180 ; XXVI, 61). 



Byana. — See Biana. 



Byrenconda See Bairenkonda quartzites. 



Calderite. — Name given by H. Piddington (Journ. As. Soc., Beng., 

 XIX, 145, 1850 ; XX, 207, 1852) after James Calder to a 

 massive lime-garnet rock from the Hazaribagh district. See 

 F. R. Mallet [Rec, Geol. Surv., Ind., VII, 34, 1873 ; Man. 

 Geol. India, pt. IV, Mineralogy, 89, 1887). 



Carbonaceous System.— Name applied by R. D. Oldham (Rec., 

 Geol. Surv., hid., XXI, 133, 1889) to the unfossiliferous rocks of 

 the Outer Himalaya consisting of the Simla slates, the Blaini 

 beds, the Infra-Krol series and the Krol series. So called on 

 account of the black, carbonaceous shales which occur in the 

 Krol and Infra-Krol series as well as in the supposed equi- 

 valents of these beds in other areas. The Carbonaceous 

 system is practically the same as Medlicott's " Himalayan 

 series " (Mem., Geol. Surv., Ind., Ill, 17, 21, 1864) ; it was once 

 considered to be about Permo-Carboniferous in age on account 

 mainly of the included Blaini boulder-bed ; but these unfossili- 

 ferous Himalayan rocks are now grouped with the Purana 

 systems of Peninsular India. 



Cardita Beaumonti beds.— Olive shales and sandstones in the Laki 

 range of Sind have been known generally by the abundance of 

 Cardita (Venericardia) Beaumonti d'Arch. which they contain. 

 This and the associated fossils show a distinctly Cretaceous 

 character, but have nevertheless strong Tertiary affinities (W. T. 

 Blanford, Mem., Geol. Surv., Ind., XVII, 34—36, 1880). 

 Blanford (Mem., Geol. Surv., Ind., XX, 108, 1883) thought 

 the preponderance of evidence was in favour of regarding 

 these beds as Eocene or possibly as passage beds between 

 the Cretaceous and Tertiary. Similar beds have been found 

 in the Salt Range of the Punjab, where, on account of 

 their colour they were referred to as the " Clive group " by
