DESCRIPTION OF SPECIES. LN) 
while all the intervals between the secondary nerves and between the 
festoon and the margin are filled in with large polygonal areoles. 
These leaves resemble those described by Professor Heer (FI. Foss. 
Arct., Vol. III, Part II, pp. 114-115, Pl. XXXII, figs. 11-13). In outline 
they seem intermediate between the two forms which he calls Chondrophyl- 
lum Nordenskiéldi and C. orbiculatum, the outline being somewhat more like 
the former, the nervation like the latter. I have therefore thought it better 
to give to our leaves a distinct name. 
The genus Chondropliyllum is ill defined, and more material will be 
needed before anything definite can be said in regard to its limitations or its 
relations to living plants. Professor Heer puts the species referred to above 
into the family of the Ampelidez, states that fruits which he considers 
those of the Panax were found with them, and suggests that they belonged 
to this genus or some related araliaceous plant. 
Locality: Woodbridge. 
CHONDROPHYLLUM RETICULATUM Hollick n. sp. 
PiP NT, fess 657. 
Leaves orbicular (?) in outline, abruptly narrowed at the base, entire; 
midrib and secondaries fine, about equal in thickness, all gradually losing 
themselves in the parenchyma of the leaf or merging into the delicate 
reticulated nervation of the blade. 
The two imperfect specimens represented are apparently referable to 
this genus and have much in common with C. orbiculatum Heer. The 
imperfect upper part of both of our specimens leaves us in doubt as to 
the exact character of the apex, which may have been emarginate. 
No memorandum in regard to either name or locality accompanied 
either the specimens or the figures—A. H. 
Order CORNACE. 
CoRNOPHYLLUM VETUSTUM Newb. n. sp. 
Pl. XIX, fig. 10. 
Leaves elliptical, 7" or 8™ lone by about 4°™ wide, points subacute, 
base slightly wedge-shaped, short petioled, margins entire; nervation deli- 
cate, midrib straight, lateral nerves opposite or alternate, about seven pairs,
