380 J. E. Teschemacher on the 
Of Asreroruyuurres | have, 
A. comosa, Lindley & Hutton, from Nova Scotia, and 
A. equisetiformis, Brongn., from Mansfield. 
Of Hippurrres, Lindley & Hutton, 
H. longifolia, from Nova Scotia. 
FILICES. Unger, Syn. Plant. Foss. 
Pecopteripes, Id. 
Beinertia, ? Gópp. Syst., (plate XXXV. fig. d.) Although 
possessing but a few fragments, they so closely resemble Góp- 
pert’s fig. 5, tab. XVL, that I have ventured to place it here, 
believing however, as I have before stated, that it should be 
classed with Neüropterides. From the anthracite coal 
at Mansfield, Massachusetts. 
Diplazites longifolius, Gópp. 
Pecorrenris longifolia, Brongn. 
te XXXVI. fig. c. From the shale overlying the coal, 
Portsmouth, Rhode Island. 
Alethopteris lonchitides, Sternb. 
P. lonchitica, Brongn. 
From Pictou, Nova Scotia. 
A, Serlii, Gópp. 
P. Serlii, Brongn. 
Plate XXXV. a, a. From Mansfield. From what I have 
seen, the two varieties of Brongniart, Europea and Americana, 
I think, are not distinct enough for a division. 
A, muricata, Gópp.?. From Mansfield. 
P. muricata, Brongn. ? : 
It is with much doubt that I place this fragment with A. 
muricata. The impression on the stone is beautifully clear, 
and, if the leaves did not lap over, I should be rather inclined 
to refer it to A, Ottonis, Gépp., tab. XXXVII, fig. 3» 4
