edges; nerves strong, depressed, spreading and forking in a flabellate 

 manner. There is a larger and broader form of leaf much scarcer than 

 the small leaf, which may be of this species; it is twice as large as the 

 small leaf, with finer and less strongly marked nerves and is flatter and 

 smoother than that leaf; these larger leaves are broadly ovate and ra- 

 pidly narrowed to a subsessil© base. 



Fruit bracts. — Certain small branches bear a modified form of the 

 small leaf which has the appearance of a fruit bract; these bracts are 

 shorter and broader than the small leaf and are more strongly nerved; 

 they are concave at the centre and toward the base and often strongly 

 revolute at the edge; they thus resemble the scales of some pine-cones. 



Fruit. — ^The fruit has in no case been found attached, but it is of 

 quite common occurrence with the other parts of the plant, and no other 

 species occurs with it in the examples studied. The fruit was a small 

 ovate acine, or berry, evenly curved all around, except that the anterior 

 part of the side was somewhat straightened, and the upper end bluntly 

 rounded. The substance of the fruit was denser in the posterior central 

 two-thirds, but there was no central nut as in Cardiocarpon. There was 

 a dense skin or exocarp to the fruit which as preserved shows a minute 

 longitudinal striation, and when the surface is well preserved a broken 

 transverse striation also. Several examples in which the centre of these 

 fruits are hollowed (from decay) would further indicate that they did 

 not contain a nut. 



Size. — The (supposed) large leaves or pinnules were 8 x 10 mm., 

 )0r less; the small leaves were 4 x 10 to 4 x 4 mm. across. The largest 

 fruits were 4^/2 x 6 mm., many flattened examples were 4 x 514 mm. 



Horizon and Locality. — Found in a bed of tlie Dadoxylon sandstone, 

 about 100 feet from the base at Duck Cove, Lancaster, N.B. Collected 

 by Mr. A. G. Leavitt. 



The large leaves of this species are much like those of Aneimites 

 acadica, Dn., in form, but are smaller and have much shorter and stouter 

 pedicles, or they are sessile. The longer examples of the small leaves 

 may be compared to those of Archœopteris minor, but there are fewer on 

 the rachis, and the arrangement and nature of the fruit is quite different 

 from the fruiting pinnae of that species. 



A plant which for its fruiting parts may be compared with this 

 species is D. White's Aneimites fertilis, (or Adiantites), and which that 

 author has attached to Sphenopteridse or to the Neuropteridae [it would 

 seem more nearly allied to the former by the arrangement and venation 

 of the pinnules] . In this the fruit is quite nearly like that of our species 

 in form, but is much smaller.^ In this species Mr. White was fortunate
