preponderance of phanerogams, there being only 10 species not 
belonging to this class. This approaches somewhat closely to 
the proportions existing in the present between the higher crypto- 
gams and the dominant types, and suggests at once the compara- 
tive modernness of the Amboy flora. 
Of the 10 cryptogams enumerated, one is regarded as an alga, 
one as an hepatic, and the remainder are ferns, one of the most 
interesting being an undoubted Ophioglossum. The Cycadaceae 
are represented by 3 genera and 5 species, and the Coniferae by 
15 genera and 19 species. No monocotyledons were obtained. 
The angiospermous dicotyledons are represented as follows: 
Juglandaceae, 1 genus and species; Myricaceae,1 genus and 7 
species; Salicaceae,2 genera and 5 species; Fagaceae,1 genus 
and species ; Ulmaceae, I genus and species; Moraceae, I genus 
and 3 species; Proteaceae, 2 genera and 3 species; Magnoliaceae 
3 genera, II species, of which the remarkable Lzriodendropsis is 
described as new ; Menispermaceae, I genus, 2 species; Lauraceae, 
4 genera, 8 species; Rosaceae, I genus and species; Leguminosae, 
7 genera and 10 species; Aquifoliaceae, 1 genus and species; 
Celastraceae, 2 genera, 11 species; Aceraceae, I genus and species ; 
Rhamnaceae, 2 genera and 2 species; Vitaceae, I genus, 2 species ; 
Tiliaceae and Passifloraceae each with 1 genus and species; 
Myrtaceae, 1 genus, 5 species; Araliaceae, 3 genera, 12 species; 
Cornaceae, 1 genus and species; Ericaceae, I genus, 4 species; 
Myrsinaceae, 1 genus, 3 species; Sapotaceae, Ebenaceae, Asclepia- 
daceae and Caprifoliaceae each with a single genus and species; 
uncertain affinities, 8 genera and 19 species. 
This brief enumeration brings out clearly the great diversity 
of the flora, for there are not less than 30 well marked modern 
families represented, and often with a goodly number of species. 
It seems unreasonable to suppose that this complex dicotyledonous 
flora should be anywhere near the actual beginning of this great 
class of plants, as has recently been suggested. It must have had a 
long period of development before such diversity could have been 
attained. 
From the geological side this work furnishes a valuable and 
timely contribution to the controversy regarding the presence of 
Jurassic strata along the Atlantic border. The Amboy Clays are
