4. — Gypseous clays, with flaggy and rutbly sandstone, red Inmps and purple tands ; 



Selemnifes strongly channeled, casts of bivalves, and small Amnelid tracks. 

 3. — Light-grey sandstone, thick -bedded, hard, calcareous portions, with glistening 



cleavage planes on fractured surface ; black where exposed. 

 2. — Gypseous clays and yellow earthy shales. A few Ammonites of undetermined 



species, probably Oxfordian, coated with gypsum. 

 1 . — Tellow sandstones and grits, more or less calcareous, also purple conglomerate beds 



nearly vertical. Ammonites, Belemnites, TerehratxdcB, Fleiirotomarice, &c. 



Ifote. — It is possible that Nos. 1 and 2 in the above section are portions of Nos. 6 and 7, 

 which they closely resemble, let down by a fault undetected in the soft shaly beds. PossUs 

 were most abundant in Nos. 5 and 6 and in certain calcareous and conglomeritic bands 

 in the clays above. The pseudo-pebbles that form these bands are of tough light-colored 

 clay, often penetrated by cavities of Fholadidm or some boring molluscs. 



About this horizon to the westward, a shale zone occurs, contain- 

 ing a new species of Ammonite allied to A. Pottingeri, below which are 

 other fossiliferous beds, with Terehratula, JRliynclionella, Belemnites, and 

 small Ammonites very common. The sandstones of No. 3 are not at all 

 unlike some of the upper series of the Jurassic : a hard bed, occurring- 

 in the middle, has a peculiar crystalline appearance reflecting' light 

 from cleavage planes on the fractured surface ; this weathers black 

 where exposed. The whole section comprises a thickness of about 1,500 

 feet of strata. The continuation of this section upwards may be traced 

 near Juddoora village, two miles to the west, where No. 14 of the above 

 list is exposed at the top of the ghat, and overlaid at the village by a 

 hard, calcareous grit containing a few Belemnites and spines of Eclii- 

 noidea. To this succeeds a thick group of shales, with nodular and 

 gritty bands, containing a few Ammonites, Haploceras tomiphorum, and 

 Aspidoceras Apenninum, and these pass upwards into the usual un- 

 fossiliferous thick-bedded, yellow and pinkish sandstones, with flaggy 

 and shaly bands, that underlie the more characteristic beds of the upper 

 division.
