r — L. Prang & Co., Art and Educational Publishers, Boston, Mass., 
announce the publication of The Yellowstone National Park, and the 
Mountain Regions of Portions of Nevada, Idaho, Colorado, and Utah. 
Described by Professor F. V. Hayden, Geologist-in-charge of the U. S. 
Government Expeditions to the Yellowstone Valley of the Years 1871 
` and 1872, and of the U. S. Geological and Geographical Survey of the 
Territories, and Illustrated by Chromo-Lithographic Reproductions of 
Water-Color Sketches taken by Thomas Moran. 
— It is proposed to invite governmental geological surveys, learned . 
societies, and private individuals, throughout the world, to send to the 
International Exhibition to be held at Paris in 1878 such collections as 
will make the geological department of that exhibition as complete as 
possible. In order to take advantage of the collections which may thus be 
brought together it is moreover proposed to convoke an International Ge- 
ological Congress, to be held at Paris at some time during the Exhibi- 
tion of 1878, and to make that congress an occasion for considering 
many disputed problems in geology. All American geologists interested 
in this project are invited to communicate with Prof. T. Sterry Hunt, 
Boston, Mass. 
— Among recent zodlogical discoveries of interest is a new species of 
Echidna from New Guinea; a second species of that interesting lizard, 
Sphenodon, in one of the New Zealand Group; a new Leptocardian fish 
allied to Amphioxus, from Australia, named by Dr. Peters, Epigomethys 
cultellus ; while the Persian deer (Cervus maral) is regarded by Dr. Se- 
vertzoff as identical with the Wapiti (Cervus Canadensis). 
— A bed of pink coral has been discovered by the captain of the U. S. 
steamer Gettysburg, on her passage from Fayal to Gibraltar, in latitude 
36° 30! N., longitude 11° 38' W. The least depth found was 30 fath- 
oms, but the captain has no doubt that the coral comes to the surface at 
some point near the anchorage. Twenty. miles west of the bank a depth 
of 16,500 feet was found, between this and Cape St. Vincent, 12,000 
feet. The bank is rich in valuable coral of light pink shades. Full de- 
tails of the discovery have been sent by the commander of the Gettys- — 
burg to the Navy Department, Washington, by mail. 
— Professor F. de Hochstetter, formerly geologist of the Novara Ex- 
pedition, and a distinguished investigator of the geology of New Zealand, 
has been appointed Superintendent of the Museum of the Imperial Geo- 
logical Institute of Austria, and intrusted with its reorganization a¢cor®- 
ing to the plan approved by his Majesty. The construction of the new — 
_ Museum of the Institute is in full progress. Mr. Francis Foetterle, the 
__ Vice-Director, has recently died, aged 53 years. He was attached to the 
Institute since its foundation in 1848.
