distribution of the resident species, the times of arrival and 
departure of the migrants, and the localities to which the summer 
visitants resort to breed. 
It is hardly necessary to add, that each contribution to the forth- 
coming report would be accredited to its proper source. In order 
to be available for the object in view, manuscripts should be re- 
ceived not later than June next.— Address Dr. E. Coves, U.S. A.,

GEOLOGY. 
On THE Tusk or LoxoLopHopon cornutus.— Professor Marsh 
asserts that I have reversed the positions of the tusks of this spe- 
cies, placing that of the left side on the right, etc. This statement 
is not true, as I have carefully distinguished the sides in my de- 
scription (Short-footed Ungulata, etc., p. 10). In my plate 2d the 
inner side is not represented as the outer, as the inner surfaces 
of attrition are omitted, and the external represented. Like his 
other charges this one results from a misapprehension. Havin 
seen a photograph in which, for the assistance of the artist, the 
left tusk was taken on the right side, he at once concludes that 
my lithograph represents it in the same position.— E. D. Cope. 
ioe ANTHROPOLOGY. 
Existence or Man ıs THE Miocenr.—I have received a letter 
from Mr. Edmund Calvert, in which he informs me that his 
brother, Mr. Frank Calvert, has recently discovered, near the 
Dardanelles, what he regards as conclusive evidence of the exist- 
ence of man during the Miocene period. Mr. Calvert had previ- 
ously sent me some drawings of bones and shells from the strata 
in question, which Mr. Busk and Mr. Gwyn Jeffreys were good 
enough to examine for me. He has now met with a fragment of a 
bone, probably belonging either to the Dinotherium or a Mastodon, 
on the convex side of which is engraved a representation of a 
horned quadruped, ‘with arched neck, lozenge-shaped chest, long 
body , Straight fore legs and broad feet.” There are also, he says, 
traces of seven or eight other figures, which, however, are nearly 
obliterated. He informs me that in the same stratum he has also 
found a flint flake, and several bones broken as if for the extrac- 
_ tion of marrow.
