{aaaTTHEW] ON SOME NEW SPECIES OF DEVONIAN PLANTS 189 
HYSTERITES ANEIMITIS, N. sp. 
Conceptacle in groups or scattered over the surface of the maia 
stems and larger branches of Aneimites Acadica. They vary from a 
circular form to a broad oval and have a raised border with somewhat 
depressed central area, the elongation where seen is in the direction ot 
the length of the ferns stipe; they are quite abundant on a few stems, 
and the groups of conceptacles are often clustered lengthwise of the 
stem. Some examples (perhaps of another species) show a somewhat 
pointed end to the conceptacle and a longitudinal depression or slit 
along the middle. 
Size—Diameter, 14 mm.; the largest may reach 2 mm. in th» 
long diameter. 
Horizon and Locality—In the Upper Devonian shales of Gas- 
pereau R., N.S. Not infrequent on the stipes or stems of Aneimites 
- Acadica. 
This species has a habit similar to that of Hysterites cordaitis 
Grand Eury, as depicted by David White in his Monograph on the Lower 
Coal Measures of Missouri.! In that species all the conceptacles show 
an oval form, but such form is exceptional in H. Aneimitis. It seems 
most apt to occur where the stem shows a strong vascular lineation. 
In the smaller and less woody branches this tendency is not marked. 

DESCRIPTION OF THE FIGURE. 
Fic. 3.—Hysterites aneimitis. Imprint of part of a rachis of Aneimites 
Acadica, showing the imprint of groups of conceptacles of this species of 
Hysterites, some are slightly elongated. Natural size. From Upper Devonian 
shale, Gaspereau R., N.S. 
PSILOPHYTON PRINCEPS, Dawson. 
The fossils at Gaspereau which I have referred to this species have 
the following charactors: The stems are from 5 to 15 mm. wide, and 
fork at a narrow angle; they show the irregular surface of non-continuous
