At Keaseby’s clay pit, on the Raritan River, near Perth Amboy, a 
conifer occurs in great abundance which closely resembles that described 
by Heer (loe. cit.) and called by him Juniperus macilenta. 'The branchlets 
are apparently more regularly and gracefully expanded, with a pinnate 
arrangement that indicates that they spread on the same plane, like those of 
Thuya, and the leaves are somewhat shorter and more appressed than those 
represented in Heer’s figures. Still, the resemblance is striking, and it has 
seemed to me probable that the species is the same. This is further indicated 
by the fact that thickly scattered among the twigs there are cone scales and 
cones, though the latter are very badly preserved. The cone scales are evi- 
dently identical with those described by Heer under the name of Dammara 
microlepis (Fl. Foss. Arct., Vol. VI, Abth. IT, p. 55, Pl. XL, fig. 5), and prob- 
ably with those described by him as Dammara borealis (op. eit., p. 54, PI. 
XXXVII, fig. 5). These scales terminate below in a comparatively long 
and narrow neck for attachment, expanding above to form an elliptical disk, 
the summit of which consists of a crescentic, smooth band, terminating 
above in a point. This was evidently the exposed portion of the scale. 
Below the summit the scales are thickened, striated, and longitudinally 
cracked, the cracks being filled with amber. In a few instances the scales 
are grouped together, and in one or two cases they compose cones, now 
much decayed, and yet showing that the form was ovoid and that the 
number of scales must have been twenty or more.
