"Von Buch), which has been removed from the Trias by Br. Oldham, 

 and declared to belong to beds anterior to that epoch. 



There is therefore a strong probability that both the Zeeawan 

 bed (Productus semireticidatus, Athyris Eoyssii &c.) and the Weean 

 bed (Sjoir. f. Stracheyii, Spir. Keilhavii) exist in the ranges near the 

 Niti Pass, but have been much denuded and broken in loose frag- 

 ments along the section followed by Colonel R. Strachey. 



Then comes what Colonel Strachey supposed to be Muschelkalk, 

 and which Mr. Salter refers to the Keuper and Hallstadt bed of the 

 Upper Trias. I cannot refrain from expressing a suspicion that a 

 few of the shells referred to' these beds do not really belong to them, 

 and that fossils of various ages have been mixed, either from collect- 

 ing them, without due care being paid to the strata in which they 

 were respectively found, or from careless packing. There is such 

 a great likeness between the figures of some of the Triassic Am- 

 monites of Mr. Salter and those of the carboniferous ceratites of 

 M. BeKoninck,* (see Ammonites Blanfordii, Salter, nov. sp. and 

 Ceratites Lyellianus, Dekon. nov. sp.) that one finds it difficult to 

 decide between these two great authorities. The species of am- 

 monites figured in the Palaeontology of Niti have nearly all the 

 ceratite-like sutures usual in triassic ammonites in Europe, and 

 therefore much resemble deKoninck's ceratites. 



It may be advanced, on the other side, that M. BeKoninck's 

 ceratites belong to triassic beds ; but these ceratites are to be 

 seen in the Rotta Roh associated to some of the fossils which I 

 have given as characteristic of my Weean bed of the carboniferous 

 in Kashmir and the Punjab ; and a portion at least of this Weean 

 bed would have then to be made over to the Trias. Unfortunate- 

 ly for this view, the mixture of Weean and Zeeawan fossils in 

 some layers of the Rottah Roh (described in para. 60 of this 

 paper), does not allow us to make the Weean anything but car- 

 boniferous, unless we are prepared to regai'd the Prod, semi-reticu- 

 latus, the A. Boyssii, the A. Sabtilita and other such essentially
