since been collected by Mr. Jex for Mr. R. F. Damon, of Wey- 
mouth, England, and these have been acquired by the Edin- 
burgh and British museums. These later collections have 
yielded some additional species, one from Scaumenac bay, 
which was described by Dr. Traquair in 1890; and six from 
near Campbellton, three of which were described by Dr. Tra- 
quair, one in 1890 and two in 1893, and three by Mr. A. Smith 
Woodward in 1892. The latest novelty from Scaumenac bay 
is a new Cephalaspis (C. laticeps Traquair), of which it is said 
that "this is the first occurrence of a cephalaspid in rocks of 
later age than the Lower Devonian."* The three additional 
species from Campbellton, that Dr. Traquair has described, 
are two ichthyodorulites (Gyracanthus incurvus f and Cheirac- 
anthus costellatus);J; and another Cephalaspis (C. jexi).§ The 
three from the same locality described by Mr. A. Smith Wood- 
ward, in the eighth volume of the Third Decade of the Geo- 
logical Magazine, are all elasmobranchs, viz., Acanthodes se- 
mistriatus, Protodus jexi, and Diplodus problematicus, the 
latter being the type of Traquair's genus Doliodus,,] published 
in 1893. 
In 1882 Sir William Dawson determined or described the 
fossil plants from Scaumenac bay, four specifically and four 
only generically, and identified six species of fossil plants from 
near Campbellton with the Psilophyton princeps, P. robustius, 
Arthrostigma gracile, Leptophloeum rhombicum, Cordaites 
angustifolia and Prototaxites logani of the Gaspe sandstones. 
He asserts that the plant and fish-bearing beds at Scaumenac 
bay are "no doubt the equivalents and continuation of the 
upper part of the Gaspe sandstones," and that the fossil plants 
from near Campbellton are "perfectly identical with the lower 
part"^ of these sandstones.
