DESCRIPTION OF SPECIES. 155) 
The great number of these scales mingled with the branches of the 
conifer in question indicates very strongly that we have here the fruit of 
the tree. If so, it is evident that this was not a Dammara, and equally 
evident that it was not a Juniperus. The form of the cones and the cone 
scales is sufficiently like that of Dammara, but the foliage is as far as pos- 
sible removed from it. The Dammara-like scales have been found in a 
number of the clay pits of New Jersey, and branches have been collected 
at Cutler’s bank, in Woodbridge; so that it is apparent that the tree was of 
frequent occurrence in the forests that surrounded the estuaries in which 
the Amboy Clays accumulated, and we may therefore hope that in the 
future material will be obtained that will enable us to reconstruct this tree 
and determine with accuracy its botanical relations. 
Localities: Keaseby’s clay pit, Woodbridge. 
Note.—Dammara borealis Heer, from South Amboy, and D. microlepis Heer, as 
figured by Heer, are shown on PI. X, figs. 8, 9, of this monograph, but no specimens of 
the scales mentioned by Dr. Newberry as occurring with the branches of J. macilenta 
were found in any of the collections.—A. H. 
Moriconia cycLoroxon Deb. & Ett. 
Pl. X, figs. 11-21. 
Moriconia cyclotoron Debey & Ettingshausen, Urweltl. Acrobryen d. Kreidegeb. vy. 
Aachen (Denkschr. Wien. Akad., Vol. XVU, p. 239), pp. 59,64, Pl. VI, figs. 
23-27. 
This, the most beautiful of conifers, was first described by Debey 
and Kttingshausen in Die Urweltlichen Acrobryen von Aachen (loc. cit.), 
among ‘Plante incerte sedis filicibus affines,” but as their specimens were 
very imperfectly preserved and the general outline of the leaf-bearing 
twigs is much like that of some ferns, it is not surprising that they were 
mistaken as to its affinities. Subsequently Professor Heer met with it 
among the fossil plants brought from Greenland and described it (Flora 
Fossilis Arctica, Vol. III, Part II, p. 97, Pl. XXVI, fig. 18) as Pecopteris 
kudlisetensis. Afterwards better specimens were brought to him from 
Greenland which revealed the true character of the plant, and these he 
describes and figures (op. cit., Vol. VI, Abth. II, p. 49, Pl. XX XIII, figs. 1-9)
