above line. Both powers relinquish any existing protectorates 
within the limits of the territories assigned to each, except that 
Victoria, Ambas bay, will still continue a British colony. Ger- 
many also engages to refrain from making acquisitions of territory 
or establishing protectorates on the coast between Natal and De-

African News—M. de Brazza reached Paris November 12, 
1885. He states that the whites and natives of the territories 
belonging to France are on the best of terms. Natives are being 
recruited to form an army. 
State has commissioned several geographers to execute maps of 
the entire State. Lieyt. Massari is surveying the right bank of 
the Congo between the Alenia and Mobangi. M. L. de Guiral 
is engaged in exploring the San Benito, about seventy miles north 
of the Gabon. The river is navigable only for twenty-two miles. 
There is a small lake eighty-seven miles from the coast, and three 
tributaries enter the San Benito above the first falls. 
Evrore.—European News—A search for the true source of the 
Danube seems strange at this late date; yet M. de Wogan has 
found that it does not rise, as has been stated, in the gardens of 
the Prince of Firstenburg, at Donaueschingen. It is formed by 
the union of two small streams; the Brig or Brigach and the 
reg or Bregach. The first rises at Saint Georges, north of the 
Tryberg mountain and about a mile from the source of the 
Neckar, while the second rises at St. Martin, west of Tryberg 
and twenty miles from Donaueschingen, where the two streams 
unite.——The range called Umb-dek, in the Kolu peninsula, 
about a thousand meters high, is the highest land in European’ 
Russia north of the Caucasus. Bosnia and Herzegovina have

THE VERTEBRATE FAUNA OF THE TiIcHOLEPTUS Brps.—In the 
Report of the U.S. Geological Survey of the Terrs., Vol. 1, p. 18- 
(1885), I have given some of the characters of this horizon and 
its fauna. It is intermediate in all respects between the Middle — 
and Upper Miocene formiations of the West, as represented by 
E rep Dy 
shie John Day and Loup Fork beds. It was first èxplored in the 
r At the latter locality it is seen to rest on the John Day 
ds, as stated by Mr. Wortman, and as indicated by the collec-
