Prof. Ansted on the Geology of Andalusia. 155 
son, and Mr. E. Hull, Prof. Buckman commenced the description of 
the different deposits from the basement-beds of the Inferior Oolite 
to the Portland Oolite, inclusive. In treating of the Inferior Oolite, 
the author reviewed the opinions of Murchison, Strickland, and 
Brodie on the relations of the members of this lowest part of the 
series, and criticised the views lately brought forward by Dr. Wright 
as to the association of the Inferior Oolite sands with the Lias, rather 
than with the Oolite. In this collocation Prof. Buckman does not 
agree, believing that, although some of the shells from the fossilife- 
rous beds accompanying these sands are peculiar, and, especially as 
regards a few of the Ammonites, are sometimes Liassic in their type, 
yet by far the greater portion of the fauna, including the local and 
non-migrating mollusca, is characteristically Oolitic ; and that the 
two particularly Liassic Ammonites that have been brought forward 
as evidences of the Liassic character of these sands were derived from 
the true Lias, far below the sands in question. After the considera- 
tion of these basement-beds of the Inferior Oolite, the author 
described in detail the geological characters of the several members 
of the Oolite series, viz. 1. the Inferior Oolite; 2. the Fuller’s 
Earth; 3. the Great Oolite, with the Stonesfield Slate; 4. the 
Bradford Clay; 5. the Forest-marble; 6, the Cornbrash; 7. the 
Oxford Clay and Kelloway Rock; 8. the Coral-rag; 9. the Kim- 
meridge Clay ; and 10. the Portland Oolite and Purbeck beds at 
Swindon. The author differed in the details of this description from 
_ previous writers in several respects; and, in conclusion, expressed a 
hope to be enabled to offer remarks on the physical conformation of 
this Oolitic district, on the paleontology of the strata, and the geo- 
logical changes thereby indicated, at some future period. 
3. “On the Geology of the Southern part of Andalusia between 
Gibraltar and Almeria.” By Prof. D. I’, Ansted, A.M,, F.G.S. 
In this paper the author first described the mica-schists of the 
Sierra Nevada, in which, on the south-west, irregular deposits of 
highly argentiferous copper occur. On the north-west, crystalline 
limestone, with galena, overlies the schists; and thick beds of ter- 
tiary marls repose on the limestone. Superficial detritus is irregu- 
larly spread over all. Thick beds of shale with copper-ore are at 
some places found between the old schists and the limestone ; 
near Malaga they pass into a conglomerate and then into triassic and 
jurassic beds, These shales and the schists are both traversed by 
serpentine-veins. Not far east of Malaga the author observed a 
black foetid magnesian limestone (distinct from the dolomites of the 
Sierra de Mijas «djacent), underlying shales and sandstones on which 
rests a grit containing remains of Calamites or Equisetites. This 
limestone corresponds in position with the conglomerates between 
the shales and sandstones near Malaga, which last extend along the 
coast from some distance west of Malaga to the eastern side of the 
Sierra Nevada. They comprise white and red sandstones with marls, 
and are occasionally gypsiferous and lignitiferous. Near the top 
of the series a white sandstone, used for building, has afforded the 
Sea above referred to, 
ext in order are the blue and black limestones of the Sierra
