L. Lesquereux on the Coal Formations of North America. 377% 
species. Fine specimens of these supposed Antholites have been 
cea by Lindley and Hutton, trom the Coal Measures of 
ngland, and by Dr. Newberry, from our own coal fields. I 
have found also some small specimens of these peculiar remains 
at Pomeroy, Ohio, and at Port Carbon, Penn. All these, either 
naked or bracteated nutlets, appear to be only branches of fruit- 
ing stems of some ferns of an unknown t 
a likeness of position to those of the Danaew of our time. But 
not of direction, indeed; for, in this species of our Coal Measures, 
the nervules are arched and dichotomous or forking like those of 
atrue Neuropieris. Another remarkable specimen, preserved in a 
pebble of carbonate of iron, from Morris Co., Illinois, represents 
also a branch of a species of fructified Neuropteris. In this, the 
short, ovate, slightly pointed leaflets, about one inch long, and 
eply cordate at the base, are attached to the rachis by a short 
pedicel. They are slightly convex or inflated in the middle, with 
’ Narrow margin apparently reflexed, but at the same time flat- 
tened all around. The scarcely visible veins are distant and 
’pparently forked once, or the surface, generally quite smooth, 
‘8 marked by irregular undulate cross-wrinkles, somewhat re- 
Sembling those of the fructifications of an Odontopterts. In this 
Case, the spores appear to be placed in large flakes, covering, 
xcept a narrow border, the whole of the lower surface of the 
leaves, as is the case with the fruit-bearing leaves of some species 
_  Osmunda of our time. Thus, in the same genus, there are 
 §pparently two far different types of fructifications. 
___A peculiar specimen of fruiting fern, belonging to the Cabinet 
of Amherst College, and labelled, Mansfield ? Mass., shows a 
Pinnately divided frond or rather pa whose secondary 
Tachis is pinnately subdivided into short branches, bearing nu- 
™erous groups of fruit dots, placed four by four on each side of 
&common branchlet. . They appear attached to it, each by a very 
slender pedicel; and, round as they are, with a depressed point or
