THE GEOLOGIST. 
PEOCEEDINGS OF GEOLOGICAL SOCIETIES. 
Geological Society. — June \7th. — 1. " On the Eelations of the Cro- 
marty Sandstones containing Ecptilian Footprints." By the Eev. George 
Gordon, LL.D., and the Eev. J. M. Joass. With an Introduction by Sir 
E. I. Murchison. 
In the introduction Sir E. I. Murchison gave a sketch of the geology of 
the Tarbatness promontory, which is composed of variously coloured sand- 
stones, having a conformable dip to the jN^.W. In these strata the authors 
had found footprints (of animals believed to be Eeptiles) similar to those 
found in the sandstones on the coast of Elgin ; and it was therefore desi- 
rable to prove whether these rocks really belonged to the Palaeozoic series, 
or, as some geologists suppose with regard to the Elgin sandstones, to tlie 
Trias. In order to solve this problem, if possible, the Eev. Mr. Joass 
made a careful survey of the coast from Geanies to Tarbatness Lighthouse, 
and round along the north shore of the promontory to the inlet at Inver, 
and found a conformable succession between the undoubted Old lied Sand- 
stone of Geanies and the track-bearing sandstone of Tarbatness. 
The Eev. Dr. Gordon gave a description of the various tracks ; the 
smaller kind are referred by him to an unknown Crustacean ; the larger 
and more definite impressions, however, he considered to be the footsteps 
of some kind of reptile. He also stated, as confirmatory of the " Old Eed" 
age of the beds, that the Oolitic beds of Shandwick are unconformable to 
tiie Old Eed Sandstone. 
2. "On some Tertiary Shells from Jamaica." By J. Carrick Moore, 
Esq. With a Note on the Corals, by P. Martin Duncan, M.B. London ; 
and a INotice of some Foraminifera, by Professor T. Eupert Jones. 
An examination of seventy-one species of Tertiary Mollusca from Ja- 
maica, mostly collected by the late Mr. Barrett, showed that twelve are 
still living, and that twenty-eight are common to the Tertiary beds of Ja- 
maica and St, Domingo. The same relation between those deposits had 
been found to exist liy Dr. Duncan through a comparison of the corals. 
The " Pacific " affinity of many of these shells and corals was noticed as 
confirmatory of a conclusion arrived at by the author in a former paper ; 
and it was shown, from the occurrence of Tertiary beds on the Panama 
Isthmus at a height of 250 feet above the sea, that the complete separation 
of the Atlantic and Pacific Oceans did not take place until after the com- 
mencement of the Tertiary period. The distribution and affinities of the 
Nummulina and Orbitoides \^'ere described by Professor Jones, and those 
of the Corals hj Dr. Duncan. 
3. " On the Geology and Mineralogy of a part of Borneo." By M. Cor- 
nelius de Groot. 
A collection of specimens from Borneo and Java, presented by the 
author to the Museum of Practical Geology, was accompanied by some 
explanatory notes, in which it was stated that the steam-coal of Borneo 
underlies the Nummulitic formation, and probably belongs to the " Etage 
Suessonien " of D'Orbigny. The occurrence of tin in steam-works, and 
as veins in granite, at several places in the western portion of Borneo and 
the islands of Blitong and Banka, was particularly described, as well as 
the presence of ores of copper and manganese. Some Tertiary fossils from 
Borneo and J ava were also noticed. 
4. Description of a new Fossil Thecidium from the Miocene Beds of 
Malta." By J. Denis Macdonald, Esq. 
Amongst the many fossils occurring in the lower part of the Calcareous
