part of the province, where their master is never pretended to have 

 been. 



From a vein of pegmatite in gneiss a few hundred yards east of 

 my house a fragment was broken off, which, besides the usual com- 

 ponents of quartz and felspar, contained a " white felspathic mineral 

 of fatty lustre, softer than felspar, but gritty under the agate pestle." 

 To this mineral Prof. Haughton has given the name of Hunterite. 

 Neglecting the lime and magnesia in it, which are inconsiderable, 

 it is found to consist " of five atoms of a hydrated tersilicate of 

 alumina combined with one atom of a hyaline silica of admitted 

 composition," or 



5 [Al 2 O 3 , 3 Si 3 +3 HO] + [HO, 3 Si O 3 ]. 



II. Fossils. — Almost all the discoveries of organic remains that 

 have been made since 1854 in the tertiary deposit have been beyond 

 the limits of our province. 



In addition to the list of fossiliferous localities given on pp. 362, 

 363, vol. xi. of the ' Quarterly Journal,' I would mention the follow- 

 ing sites for shells in the Hyderabad country : Dhanki, 10 miles E. 

 of UmarkhecZ or 150 S.W. from Nagpur ; Kuntur, about 20 miles 

 S.E. of Nander or 40 farther S.W. from Nagpur than Dhanki ; 

 A'mbia Kanti and Tandrsi near Ola or Olam, about 20 miles W. of 

 Nirmal and 160 S.S.W. of Nagpur; Majajonna, 20 miles W. of 

 Khair or 95 S.S.W. of Nagpur ; Dalmetta Ghat near Kondapur, 12 

 miles S.E. of Manikgad! or 120 miles S. of Nagpur ; and Wilipita 

 and YidalawacZa on N. of Tarfur (in maps Tandoor), about 25 miles 

 S.S.E. of Dalmetta Ghat. At most of these places only the more 

 common shells are found. But from two other localities in the 

 Hyderabad Territory, Karuni and Mekalgandi Ghat, the latter of 

 which was visited by Malcolmson, I have received several new 

 species of Unio. 



The most important accession, however, to our collection of shells 

 has been from a part of India still farther distant from Nagpur. In 

 the volume of the ' Quarterly Journal' above referred to, I stated 

 that I had been favoured by my friend Lieut. Stoddard with a few 

 shells partly freshwater and partly marine from the neighbourhood 

 of Rajamandri*. The hills from which these were obtained are 

 5 miles S.W. of Panga'/i, :i village 1<> miles YV. of Rajamandri on 

 the road to Madras. They reach an elevation of about ,'ioo or 400 

 feet above the level of the plain. At their base lies a red con- 

 glomeratic sandstone, overwhich there is a considerable thickness of 

 trap, compact below and becoming more vesicular above, where it 

 imbeds veins of jasper. This is surmounted by a deposit of impure 

 limestone, the upper part of which, containing the most ;hhI the best 

 of the estuarine fossils, protrudes from the slope in a layer of 1 J feet 



* Quart. Joum. vol. xi. p. 865. In a footnote a conjecture wn* thrown out, 

 whether one of the marine sheila mighJ not bo a Nm'/irru — n bypotheiu, which, 

 if true, would imply a much greater antiquity for our intettnppMD deposit than 

 I have ever been WllHngtO Moribe to it. liut there can be no doubt that the 

 shell in question WBI a 1'urrifrllti.
