182 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [June 15, 



Wherever our iritertrappean deposit is fossiliferous, there the same 

 genera and species of shells occur, not to say that they are also met 

 with in the subtrappean strata along with Pachydermatous bones, 

 On Sitabaldi Hill we have the intertrappean shell-bed near the top, 

 and the Mahadewa sandstone at the base. Now, were we to adopt 

 the Survey's view of the age of these two rocks, we should have the 

 Wealden above the jNummulitic formation. Dr. Oldham considers 

 it unlikely that Physa Prinsepii should be preserved in the strata 

 near Eajamandri ; but no improbability will be felt when it is 

 remembered that such a fragile shell as Psammobia Jonesi and others 

 still more delicate have been preserved. In adopting his « priori 

 mode of reasoning, my friend must have forgotten that a veritable 

 Physa Prinsepii was discovered at Pangac/i in the same block with 

 marine shells* ; and I may add that I saw it with my own eyes 

 before Mr. A. Schlagintweit (to whom reference is made) could bear 

 similar testimony. 



Notes on some Fossil Insects from Nagpur. 

 By Andrew Murray, Esq., F.E.S.E., &c. 



The specimens placed in my hands (thirteen in number) all belong 

 to the order Coleoptera. 



They chiefly consist of single elytra ; in one case of two together, 

 although somewhat crushed out of position ; and in another, of a 

 beautifully preserved abdomen. The tribes to which they belong 

 (so far as decipherable) are the Bupresiidoe and Curculionidce ; but 

 I cannot identify any as belonging to living modern genera, much 

 less species. This is not to be wondered at, when we consider 

 that, although in most cases it might not be very difficult to deter- 

 mine the genus and even the species of Tcnown recent insects by actual 

 comparison of such fragments as we have here, it would be quite 

 impossible to determine with accuracy the genera of neAV species 

 (however recent and fresh), although we might easily enough fix 

 upon the tribe or family to which they belong. But, if to the 

 difficulty arising from the fragmentary state of the materials be added 

 that such new species by being fossilized are deprived of all colour, 

 have lost their natural consistency, and generally have nothing left 

 but the outline of the fragment with a few faint traces of their 

 original markings, it will easily be seen that any opinion (worth 

 having) on the subject must be given with great caution, and must 

 be very much confined to a general indication of the whereabouts of 

 the animal in the series. 



So qualified, the opinion which I have formed on the specimens is 

 as follows : — • 



No. 1 (PI. X. fig. 66).— A well-preserved elytron from Takli, 

 found by Dr. Eawes (Buprestidce — Lomatus Hislopi, Murray). — 

 Elytron depressed and approaching to the form of the elytron in 

 Phcenops, turning in with an obtuse angle near the apex, and the 

 outline thence continuing nearly straight to the apex. It is now
