large extinct peccary, a wolverine, a badger, a martin, 
two porcupines, a woodchuck, and the American 
eland-like antelope. Other species represented by 
more fragméntary material include the mastodon, 
tapir, horse , and beaver, besides several species of the 
smaller rodents, shrews, bats, and others. This 
strange assemblage of fossil remains occurs hope- 
lessly intermingled and tomparatively thickly  scat- 
tered through a more or less unevenly hardened mass 
of cave clays and breccias, which completely filled one 
or more small chambers of a limestone cave, the mate- 
rial, together with the bones, evidently having come 
to their final resting place through an ancient open- 
ing at the surface of a hundred feet or more above 
their present location

Last year an allotment was made from the institu- 
tion’s funds toward the expenses of an investigation 
r— ——=— — — 
separate fossil bones were obtained, many of them of 
large size. The most notable discovery was a new 
Ceratopsian or horned dinosaur, the smallest of its 
kind known. There were portions of five individuals 
of this animal recovered, representing nearly all parts 
of the skeleton, making it possible to mount a com- 
posite skeleton for exhibition. Although Ceratopsian 
fossils were first discovered in the Rocky Mountain 
region in 1855, and portions of a hundred or more 
skeletons have been collected, this is the first indi- 
vidual to be found having a complete articulated tail 
and hind foot. It thus’ contributes greatly to our 
knowledge of the skeletal anatomy of this interesting 
group of extinct reptiles. Another find was a partial 
skeleton of one of the Trachodont or duck-billed dino- 
saurs recently described from specimens obtained in 
Canada, and its discovery in Montana greatly extends 
its known geographical and geological range. Less

of the geology of Panama. The general plan includes 
a systematic study of the physiography, stratigraphy, 
and structural geology, geologic history, geologic 
correlation, mineral resources (including coal, oil, and 
other fields), petrography and paleontology of the 
Canal Zone, and of as much of the adjacent areas of 
the Isthmian region as is feasible. 
Upon the completion of the work the institution will 
print a general account of the results, and later there 
will be published a detailed report of the geological 
data of the Isthmus and adjoining regions. 
Vertebrate Fossil Remains in Montana. 
During the summer of 1913 Mr. Charles W. Gil- 
more, of the National Museum, headed an expedition 
for the purpose of obtaining a representative collection 
from north-western Montana. Between 500 and 600

saurs, turtles, crocodiles, and ganoid fishes were also 
obtained. 
Life Zones in the Alps. 
Dr. Stejneger, head curator of biology in the 
National Museum, visited the eastern Alps towards the 
close of the last fiscal year, to make further observa- 
tions toward a determination of the limits of the life 
zones, which in that part of Europe might correspond 
to those established in North America. That a system 
of such life zones exists in Europe has long been more 
or less vaguely stated by authors, but although a 
definite correlation was established by Dr. Stejneger 
and Mr. Miller in 1904, certain points, especially the ~ 
interrelation of the zones corresponding to the so- 
called Canadian and Hudsonian life zones in America, 
were greatly obscured by the long-continued inter- 
ference of man and animals with nature, such as the
