An Ichthyolite having been found in a slab of limestone from the 

 loose mass by the river side, noticed in Dr. Bell's former paper 

 (Quart. Journ. Geol. Soc. vol. viii. p. 232), and which Dr. Bell re- 

 gards as having been forced up by the action of the river, it has 

 been forwarded to England by General Fraser ; and Col. Sykes 

 having submitted the specimen to Sir P. Egerton, he was favoured 

 by Sir Philip with the following opinion respecting the character and 

 relations of this Indian fossil fish : — 



" It belongs to the section of the genus Bapedius with single 

 pointed teeth ; — Tetragonolepis of Agassiz — not of Bronn *. It ap- 

 pears to be a new species, differing from those hitherto described in 

 the ornamental pattern of the scales. It is an Oolitic form, probably 

 of the age of the Lias." 



Col. Sykes proposes to name this second oolitic fish from the 

 Deccan, Dapedius Egertoni. 



8. On the Erratic Tertiaries bordering the Penine Chain. 

 Part II. By Joshua Trimmer, Esq., F.G.S. 



[For Part I. see Quart. Journ. Geol. Soc. vol. vii. p. 201.] 



The facts which will be described in this paper are adduced in illus- 

 tration of two points to which I have adverted in former commu- 

 nications as general phsenomena ; namely, that the elevation, to 

 which the boulder-clay of the Lower Erratics ascends, increases as it 

 is traced from the coast into the interior ; and that within areas 

 which have been beneath the " erratic " sea considerable tracts occur 

 from which its deposits have been so extensively removed, that their 

 former existence is only proved by occasional small outliers, which 

 may be easily overlooked. 



In a paper on the Erratic Tertiaries bordering the Penine Chain 

 from Congleton to Manchester, I have described the superposition of 

 the sand of the upper erratics to the boulder-clay, in the neighbour- 

 hood of Congleton and Macclesfield, as well as the cessation of both 

 at a certain height on Alderley Edge, where, however, their former 

 presence is attested by an occasional boulder of transported rock on 

 its summit. 



Both cease in the same manner on tlie steep flanks of the Penine 

 Chain, where the sandy soil might be supposed to be derived wholly 

 from the subjacent grits of the Coal-measures, if a few erratic pebbles 

 did not prove that some of the smaller particles of which it is com- 

 posed must have been transported, as well as the coarser fragments. 

 A valley, however, runs for about two miles into the chain in the di- 

 rection of the ridge on which Sutton Church stands, and this valley 

 is filled with boulder-clay, which at its eastern termination must be 

 considerably higher than the junction of the Boulder-clay with the

 gonolepis, in his Palichthyologic Notes, No. 4, at page 274 of the present Num- 

 ber of the Journal.
