No. 1.] J. W. DAWSON — PAL^ONTOLOGICAL NOTES. 11 



Schimper, and is evidently provisional, including, according to 

 him, 3'oung or basal fronds of ferns referred to other genera. 

 As there is no evidence of this in the case of the present species, 

 I see little advantage in removing it from the equally provisional 

 genus Cydojyteris, until its fructification shall have been dis- 

 covered. Should it, however, be considered desirable to remove 

 it from Ci/dopferis, I would propose for it the name of Platy- 

 jpliyllum, for which the characters of this plant as given in 

 the paper above cited and in this note may suffice as generic 



characters. 



Caidopteris (?) 



Among Mr. Foord's specimens is one that appears to represent 

 the stem of a small tree fern. It is about one inch in diameter, 

 flattened and showing on the exposed side somewhat reniform 

 scars quincunctially arranged. The best preserved leaf-scars 

 show marks of vascular bundles which sus-o-est the idea that it 

 may have given origin to the petioles of ferns ; but there is 

 nothing; to indicate whether this stem belons-s to either of the 

 species found with it. 



Plants from Comnhellton. 



Mr. Weston's collections are contained in a hard aro-illaceous 

 sandstone or arenaceous shale resembling some of the beds of the 

 lower part of the Gaspe sandstones, with which the flora also 

 agrees. 



The greater part of the vegetable remains collected by Mr. 

 Weston are stems and branches of Psilojihyton princeps and P. 

 rohustius, which are very abundant. There are also a few leaves 

 of Cordaites avgusti/olia, and in the same shale with some of 

 these, is a short stem with remains of alternate leaves or branches. 

 This may possibly have belonged to the last named species. 



There are also specimens of strobiles, about an inch in length 

 and thickly covi3red with scales or spore-cases which appear to be 

 in two rows, but this is probably deceptive and an efl"ect of flat- 

 tening. They very much resemble the strobiles of Lycopodites 

 Richardsoni from Perry, but the scales are thicker and more 

 obtuse. This is probably the fruit of some lycopodiaceous plant, 

 and may provisionally be referred to the genus Lepidostrohus. 



The beds containing these fossils evidently belong to a lower 

 horizon in the Erian than that containing the fossils collected by 

 Mr. Foord.
