such as alder and birch have been

In addition to the bullfrog group
there have been put on view recently
a Monitor group and various smaller
exhibits. The modelling of these
groups in form life; all work on both
form and color is done from the living
animal, the New York geological park
and the New York aquarium having
lent many living specimens for study.
News has been received Of the
Congo expedition of the museum,
which is being conducted in Africa un-
der the leadership of Herbert Lang
The expedition has been unusually
successful among the Mangbetu.
The collection in anthropoIogy now
consists of some 400 specimens, ac-
cording to Mr. Lang and is unique not
only on account of its numbers, but
especially by reason of the selection
that has been made throughout the
territory inhabited by the Mangbetu
and other tribes. The expedition has
travelled with caravan of 1SO men
and in the report 2,400 mammals are
listed, 1900 reptiles and 1850 birds.
Specimens include a white rhinoceros,
two elephants, a black rhinoceros and
two buffaloes.
