Agriochcerus and Artionyx.—Mr. Hatcher has lately collected 
and sent to me from the White River bad lands of South Dakota a 
number of specimens of the genus Agriocherus Leidy. This material 
demonstrates the fact that the genus Artionyx of Osborn and Wortman 
is a synonym of Agriocherus and very probably, that the specimens 
which I described under the name of ? Mesonyx dakotensis from the 
same horizon, should be referred to the same or to some closely allied 
animal. A description of this extraordinary type will very soon be 
published. W. B. Scort. 
The Haeckel Celebration.—On the 16th of February, Ernst 
Haeckel completed the sixtieth year of his life. On the 17th, the little

whom may be specially mentioned the Hertwigs (Oscar and Richard), 
Waldeyer, Arnold Lang and Hermann Credner, besides many well 
known professors of Jena itself. The chief ceremony of the day was 
the uncovering of the marble bust of the great scientific worker and 
writer, from the chisel of the eminent sulptor, Professor Kopf of Rome. 
At noon the lecture-theatre of the Zoological Institute, in which the 
greater part of Haeckel’s life work has been carried on, was crammed 
from floor to ceiling, and Professor R. Hertwig, of Munich, the pupil, 
friend and colleague of Haeckel, was called upon to unveil the bust. 
In an admirably-worded speech be alluded to the main facts of 
Haeckel’s life, and especially to his labors in the cause of science and 
scientific freedom. The unveiling of the striking bust was the signal 
of a great outburst of applause, and when this had subsided, a deputa- 
tion from some societies, the Medicinishe-naturwissensch 5 Ge- 
sellschaft of Jena and the Geographische Gesellschaft of Thüringen,

tions had come from France. As a consequence of this, the to
