Wynne — Notes on the Geology of the Punjab Salt Range. 91 



The genus Conularia (according to Nicholson) ranges from 

 Older Palaeozoic up to Liassic, but those found by Dr. Warth have 

 been at various dates attributed by Dr. Waagen to different Palaeo- 

 zoic periods. In March, 1885, he considered them probably Silu- 

 rian ; 1 in October he called them Devonian, 2 and early in the 

 present year (1886) he most strongly asserts them to be of Carboni- 

 ferous age. 3 The several fossils of this thin conglomerate layer, as 

 found by Dr. Warth, have been determined by Dr. Waagen as 

 follows: — Conularia laevigata, Morris; Conularia tenuistriata, M'Coy; 

 Conularia, cf. irregularis, Kon. ; Bucania, cf. Kuttaensis, Waagen ; 

 Nucula, sp. indet. ; Atamodesma (?) warthi, Waagen, n. sp. ; Avi- 

 culopecten, cf. limceformis, Morris; Discina, sp. indet. ; Serpulites 

 warthi, Waagen, n. sp. ; Serpulites tuba, Waagen, n. sp. All of 

 these except the Bucania are figured in Dr. Waagen's plate, accom- 

 panying his Paper. 4 



The question remains, whence came these fossiliferous pebbles 

 which do not seem to have been transported for any very great 

 distance? Their material recalls nothing with which I could 

 absolutely identify them from memory in the older groups of the 

 Salt Range, their pale colour only — if even this is an original 

 characteristic — might be more suggestive of their connexion with the 

 Magnesian Sandstone (in which I could, however, detect no fossils) 



"Writing about them, from their very locality, Pid, under date December, 1885, 

 Dr. Warth says, " From Choah-Saidun-Shah to Mackrach, I have found the thin con. 

 glomerate bank with the pebbles which enclose Oonularice, and two or three other shells, 

 absolutely uninterrupted in the ' Olive series ' (upper portion). I send you a single 

 Conularia (No. 16) which was found in a rounded-ofT state in the conglomerate. It is 

 evident that the Conularia have not become fossils on the spot, but have been brought 

 from a distant mountain as pebbles." The label of this specimen, No. 16, states, in 

 Dr. Warth's writing, that he took it "in its present state from the face of the bed." 



No person who inspects this rolled specimen can for a moment doubt the accuracy of 

 Dr. Warth's description or the derived character of itself and the other fossiliferous 

 pebbles. Dr. "Waagen's account of them, for which indeed he advances no valid reasons, 

 must therefore be received with caution or rejected, and with it almost the whole of his 

 speculative deductions regarding the pebbles themselves, the layer which contains them, 

 tbe " glacial boulder beds " of the Range, and his elaborate Palaeontological views of 

 the palaeozoic and mesozoic geology of the eastern hemisphere and other regions.
