in 1834, after the meeting of the British Association at Edinburgh). - Other frag- 
mentary remains were found at Low Moor, near Bradford. Ina paper read at a 
meeting of the Yorkshire Geological and Polytechnic Society in December 1839 
Mr. T. Pridgin Teale was able to enumerate four genera of ganoid and seven 
genera of placoid fish-remains which had been discovered in this coal-field. They 
were: Megalichthys, Acanthodes, Platysomus, and Holoptychius; Gyracanthus, 
Hybodus (Ctenacanthus), Pleuracanthus, Helodus, Ctenoptychius, Ctenodus, and 
Diplodus. In 1845 Mr. Henry Denny was able to add Petalodus to the genera 
previously known, and gives the authority of Agassiz for the occurrence of Dip- 
lopteris, but where he had not been able to ascertain. He also mentions the large 
tail of Calacanthus phillipsvi found in the Lower coal-measures near Halifax. Mr. 
Denny records the discovery of batrachian reptiles in the Belgian coal-field, and 
whilst stating that no examples had been found in this country, recommends that 
search be made for them. After this time little interest appears to have been taken 
in the subject until the discovery of a bone-bed in the Lower coal-measures. It 
occurs immediately above the Better-bed coal; it extends over an area of ten square 
miles, and has nowhere a greater thickness than half aninch. In a communication 
to the Geological Society of London in 1876 fourteen species of Ganoids and twenty- 
one species of Elasmobranchs were enumerated from this bed, several of them being 
new. Bones of Labyrinthodonts were identified by Professor Miall as those of 
Loxomma. At Tingley, five miles from Leeds, the Adwalton Cannel coal is 
worked, and associated with it a very large number of fish-remains have been 
found. These formed the subject of another paper read to the Geological Society, 
in which twenty-five species, several new, of fossil fish-remains are enumerated. 
The most abundant fish is Celacanthus tingleyensis, Davis, and it is no exaggeration 
to state that thousands of this species have been dug up. Besides the fish-remains 
already described and recorded, others await determination. These two beds have 
proved by far the most prolific, but fish-remains have been found on seven other 
horizons, including the Halifax Hard-bed coal, Black-bed coal (Low Moor), Silk- 
stone coal, Middleton Main coal, Yard or Jcan coal, and the Barnsley Thick coal. 
Altogether more than fifty species of fossil fishes have been discovered and recorded 
from the Yorkshire coal-field.

By the Rev. E. Mavis Corz, M.A., F.GLS. 
Several of the numerous lacustrine deposits on the top of the boulder clay cliffs: 
of Holderness are visible from the shore, and are shown by bands of freshwater 
marls, varying from 1 to 3 feet in thickness. Some, like that of Skipsea (in 
which remains of the Irish elk have been found), are accompanied by peat. 
Phillips noticed a lacustrine deposit at Filey, and described it as clay, with a 
small amount of peat, in all 4 feet thick. Since then the denudation of the cliff has: 
shown a section in which the peat is 6 feet thick and nearly 60 yards in width. A 
report of the flora is expected from Mr. Cash, of Halifax. The author suggests
