[MATTHEW] FLORA OF THE LITTLE RIVER GROUP NO. III 14 
The following plants were found to occur with this species —A 
species of Cordaites is quite abundant. Itis probably a variety of 
C. Robbii, Dn., but the Cardiocarpon that occurs with it is smaller, and 
less fleshy than C. cornutum of the Lower Cordaite shales. Two abun- 
dant plants are an Asterocalamites, allied to A. scrobiculatus Schloth, 
and a Calamites cf. C. Cistii, C. ef. Suckovii, also occurs, but is not 
nearly so plentiful. The remains of these four plants, according to 
Mr. McIntosh comprise three quarters of the collection (of plant 
remains) made by him from this bed. 
“Remains of ferns are rarer. There is an Alethopteris differing 
from A. discrepans, Dn., the common species of the Lower Cordaite 
Shale. A Neuropteris occurs which is not N. polymorpha, Dn., so 
abundant in the higher measures. An obscure Sphenopteris and two 
forms of Pinnularia occur, one of which is P. dispalans, Dn. 
“In consequence of the coarseness of the matrix it is difficult to 
read the intimate characters of these ferns, but it is evident that the 
flora occurring with Pseudobaiera was somewhat varied.

“Tn this form the pinnules were somewhat more than half an inch 
apart on the side of the rachis. The pinnules appear to have been 
about one and a half inches long, and were about three quarters of an 
inch wide; they were thinner than in the typical form, and the lobes 
were more spreading; also the ends of the lobes were more frequently 
and more deeply gashed; the veins also were more readily seen. 
Horizon and Locality.—Found in Plant Bed No. 2 of Hartt’s series 
(at Fern Ledges, Lancaster, N.B.)—Scarce. 
“T have had this form in my collection for many years, but thought 
it too imperfect for description. It is now clearly seen to be related 
to the plant discovered by Mr. McIntosh. 
“ At page 516 of Sir Wm. J. Dawson’s Acadian Geology, Professor 
C. F. Hartt has given a section of the strata at the “Fern Ledges” on 
the Bay Shore in which he gives the Dadoxylon Sandstone an assumed 
thickness of 300 feet. Considering this as the thickness of these sand- 
stones at Duck Cove, the following would be the relative position of the 
beds containing the fossils above described to the section studied by 
Professor Hartt.
