ON A FOSSILIFKROTJS PEBBLE-BAND. 341 



28. On a certain Fossiliferous Pebble-Band in the "Olive Group 

 of the Eastern Salt Kange, Punjab. By A. B. Wynne, Esq., 

 E.G.S. (Read April 21, 1886.) 



Not long ago I received from my friend Dr. H. K. Warth some very 

 interesting specimens, including fossil Conularice, discovered by him 

 in the Eastern Salt Range, parts of which region I had examined 

 from his bungalow at the Mayo Salt-mines, and sometimes in his 

 company. His discovery was the subject of a short paper by myself 

 read before the Royal Geological Society of Ireland, an abstract of 

 which appeared in the ' Geological Magazine ' for March 1886. 



Almost immediately afterwards, the Records of the Geological 

 Survey of India (vol. xix. pt. 1, 1886) having reached me, I found 

 therein a paper on the same subject by Dr. Waagen, of Prague. The 

 treatment of the matter in this paper and the extent to which its 

 deductions are carried with regard to the geology of the whole 

 Eastern Hemisphere are too important in their bearing upon Salt- 

 Range geology and stratigraphy to be quite passed over by an indi- 

 vidual who had the largest part of the task of examining that 

 Range for the Geological Survey of India. 



So far as the paper now referred to deals with the stratigraphy of 

 the Range, I am in a position to offer opinions the result of direct 

 observation ; where it deals with purely paloeontological matter, I 

 offer none; and where it embraces collateral questions, bearing 

 upon the geology of half the earth, depending upon stratigraphic 

 features of the Range, I claim recognition of the observed facts 

 only so far as my own part in these observations is involved, or 

 where these are supported by the independent views of others. 



The fossils discovered by Dr. Warth about a year ago in a locally 

 upper, or the uppermost thin layer of a certain Boulder-bed with 

 glaciated blocks, in the " Olive Group " of the Salt-Range series, 

 have been determined by Dr. Waagen to comprise ten Palaeozoic 

 species, which he finally (so far) decides to belong to the Carboni- 

 ferous period*. The age of this " Olive Group " having been pre- 

 viously fixed by Dr. Waagen and myself as probably Cretaceous t, 

 anything tending to throw additional light in that direction would 



* See my Salt-Range Report, Mem. Geol. Surv. Ind. vol. xiv. p. 67 &c. 

 t The fossils from this group described by Dr. Waagen are : — 



6. Atomodesma(?), Waagen. 



7. Aviculopecten, of. limjvformis, 

 Morris. 



8. Discina, sp. indet. 



9. Serpulites Warthi, n. sp., Waagen. 

 10. tuba, n. sp., Waagen. 



AU except the fourth are figured in Dr. Waagen's plate, and all except the 

 first two are given by him as cither new species or doubtful, that is to say 

 requiring further comparison. 



1. Conularia laevigata, Morris. 



2. tenuistriata, M'Cog. 



3. irregularis, de Koninck. 



4. Bucania, cf. kattaensis, Waagen. 



5. Nucula, sp. indet.
