^^Wealden Fossils from Columbia, S. America,” by John 
Plant, F.G.S. 
The author stated that in the republic of Columbia, in 
the mountain ranges about Honda on the Upper Magdalena^ 
having an average altitude of about 9,000 feet, mines of 
silver are worked, and emerald mining is carried on to a 
large extent in metamorphic rocks of Palseozoic age. Of 
the existence of fossiliferous rocks of Wealden age lying 
upon these older rocks at such a high elevation as 8,060 or 
9,000 feet he has had proof in a few fossils sent by his 
friend Mr. E. Williamson from Honda, who has been five 
years at the silver mines. 
The first is an Ammonite, or the cast of one in a black 
slatey shale, very much like shale found in the Silurian 
district of N. Wales. This Ammonite is 3 inches long, 
strongly whorled with a row of tubercles near the outer

“facies” of the species is decidedly allied to British Cretaceous 
and Wealden Ammonites. The second specimen would
