The death of George Ticknor, of Boston, a member of the 
Society, Jan. 26th, aged 80 years, was announced by the Se- 
cretary. 
On motion, Dr. H. Hartshorne was appointed to prepare an 
obituary notice of the late Dr. Rhoads. 
On motion, Prof. Kendall was appointed to prepare an obit- 
uary notice of the late Prof. Chauvenet: 
Mr. Cope reported that Mr. McNeil was prosecuting his re- 
searches in Panama, and had sent home fossils, showing 
among other things, that the back bone or water shed of the 
Isthmus was an ancient coral reef, many of the corals being 
in an excellently well preserved condition. 
THE PORT KENNEDY BONE CAVERN. 
Prof. Cope announced the discovery of a bone cave by Mr. Charles M. 
Wheatley, in the Calciferous limestone, at a point about 25 miles N. W. 
of Philadelphia. 
There had been obtained numerous remains of plants, and insects, with 
about thirty species of vertebrata. 
These consisted of Reptiles, Birds and Mammals. The first were ser- 
pents, and tortoises of several species, mostly harmless. The birds in- 
cluded a turkey and snipe. The manimalian remains were most numer- 
ous, embracing various forms. 
There were Rodentia, of American types, as IHesperomys, Fiber, ete. ; 
also Sciurus, Lepus, ete. 
There were Ruminants, several tapirs, and a small horse. Two carni- 
voxes of large size, one a cat, the other a bear, Ursus pristinus of Leidy, 
of a remarkable type, and entirely distinct from the cave bear, or living 
species of Europe and America. Remains of several Sloths were discoy- 
ered, which were mostly of gigantic size. These were referable to at 
least three species, one Megalonyx wheatleyt was new, and two Mylodons, 
one of them probably also new to science. With them occurred the teeth 
and tusks of the Z’rilophodon ohioticus (Mastodon). This animal had pro- 
bably fallen in, as the cave was rather a fissure at the point examined. 
The bones were not gnawed. ‘The fissure was 40 feet deep, 15 feet in 
width, and of unknown length. Above the cave deposit, it was filled 
with wash from neighboring hills of Triassic age.
