Matthew, professor Hartt and other local collectors in 1861, 
1862 and 1863. and more recently by Mr. W. J. Wilson and 
Dr. Matthew. The luxuriant and singularly varied fossil flora 
of the Fern Ledges has been described by Sir William Dawson 
in 1862,* by professor Hartt in 1865,! by Sir William Dawson 
and professor Hartt in i868.i and by Sir William Dawson in 
1871J and 1882.11 -The "revised list of the Pre-Carboniferous 
plants of N. E. America" in the first part of Sir William's 
memoir on "the fossil plants of the Devonian and Upper Silu- 
rian formations of Canada," published by the Dominion sur- 
vey in 1871, contains the names of seven species of fossil 
plants from the Devonian of New Brunswick, nearly all of 
which are from the Fern Ledges. In the second part of the 
same memoir, published in 1882, two additional species were 
described. 
The remarkable assemblage of air-breathing articulata and 
mullusca associated with these plant remains has been de- 
scribed by Salter in 1863,^ by Scudder in 1868,** by Sir 
William Dawson in i88o,tt and by Dr. Matthew in i888,:|: + 
and i894.§§ In the latter of these two papers Dr. Matthew 
states that the "air-breathing articulates of the plant-bearing 
bed of St. John so far recognized, consist of: 
"Insects, nine species of eight genera g 
Myriapods, six species of several genera 6
