DESCRIPTION OF THE SPECIES. 225 



A number of aments of conifers were found at the 72(1 mile-post, near 

 ]5rooke, and elsewhere, whose species can not be determined. They 

 appear to be male aments, possil)ly in some cases of BrachyphijUum, but 

 certainly of some conifer. They usually occur together in large numbers, 

 as if coming from plants near by. These will be designated as («), {h), 

 (c), etc. These aments resemble somewhat Ileer's genus Elatkles. 



Ament of Conifer (a), sp. '? 



Plato CXXXVr, Fig. 2. 



Male (?) aments ovate to oblong in shape, small, subacute at their tips ; 

 scales numerous, broadly elliptical, prolonged slightly into an acute tip, 

 spirally arranged, thin, close appressed, slightly imljricated, forming a thin 

 flat ament that leaves only a slight imprint ; length of ament about 9'""', 

 and width about 4"'°. 



Locality: Near Brooke, at 72d mile-post. 



Some fragments of shale for the space of several inches are covered 

 more or less thickly with these aments, which evidently fell from plants 

 not far distant. The shape and size of the scales and aments of this 

 species agree pretty well with some of the strobiles supposed by Saporta 

 to be male aments of species of Brachyphyllum} 



Ament of Conifer {h), sp. ? 



Plate CXXXVI, Fig. 3. 



Aments very small, broadly ovate, obtuse oi* acute at summit, some- 

 times attached to short pedicels ; size about three by six millimeters; scales 

 very thin, close appressed, slightly imbricated, numerous, spirally arranged, 

 in shape broadly elliptical to subrhombic, with a slight prolongation into 

 acute tips. 



Locality: 72d mile-post, near Brooke. 



The imprints are quite tliickly scattered on some few fragments of 

 shale, but are not so numerous as those of species («). The cones are 

 smaller than those of («).
