the appearance of forms of similar types as those under cultiva- 
tion. The presumptive evidence is in favor of the view that all 
cultivated types are removes from nature, not new originations 
by man; yet the proof is not as decisive as could be wished.”

REVIEW OF THE PROGRESS OF NORTH AMERI- 
CAN PALAZZONTOLOGY FOR THE YEAR 1886. 
BY JOHN BELKNAP MARCOU. 
iip year which has just passed has been fairly prolific in palæ- 
ontologic works and promises well for the future of Ameri- 
can palzontology.. With the exception of the death of the 
veteran palzontologist and conchologist, Isaac Lea, of Philadel- 
phia, we have to deplore the loss of no eminent workers in this 
branch of science. 
I have extended this review so as to include the vertebrates, 
which I had not touched in my similar work for previous years, 
and, although my slighter acquaintance with the subject has 
made it much more difficult for me to get the material together, 
I trust that it will be found a welcome addition by those inter- 
ested in this branch of the science. 
T. H. Aldrich publishes a “ Preliminary Report upon the Ter- 
tiary Fossils of Alabama and Mississippi” in the Geol. Sur. Ala- 
dama, Bull. No. 1, p. 18. In the Your. Cincinnati Soc. Nat. His., 
vol. viii. p. 256, he has “ Notes on the Distribution of Tertiary 
Fossils in Alabama and Mississippi.” 
J. A. Allen has an article “On an Extinct Type of Dog from 
Ely Cave, Lee County, Va.,” in the Mem. Mus. Comp. Zool., at 
Harvard College, vol. x. p. 1. Professor Shaler appends a note, 
from which one would infer that he considers the remains de- 
scribed to be of Pliocene age. 
H. M. Ami, in the Canad. Rec. Sci., vol. ii. p. 304, has a note 
“On the Occurrence of Scolithus in Rocks of the Chazy Forma- 
tion about Ottawa, Ontario.” 
Charles A. Ashburner and Angelo Heilprin have, in the Proc. 
t Joigneaux, Traite des Graines 
2 See Proc. of Soc, for P. of Ai. B, 1886, p. 68, for an article of mine on this
