a4) major portion of this number of the JOURNAL is 
lj, devoted to illustrated descriptions of the sala- 
manders, toads and frogs which have been found 
within a radius of about 50 miles of New York 
City. This article will be published separately 
as No. 20 of the Museum series of Guide Leaflets, and is intended 
for use as a handbook for the identification of the animals in 
their wild state as well as in connection with the collections on 
exhibition in the Museum. 
The collection illustrating the local batrachians may be 
found at present in the Synoptic Hall, No. 107 of the ground 
floor of the Museum Building. 
The Museum gratefully acknowledges the codperation of the 
New York Zodlogical Society in the preparation of the Guide. 
The author is Mr. Raymond L. Ditmars, Curator of Reptiles 
in the New York Zodlogical Park, Bronx Park, who also pre- 
pared the leaflet upon the local reptiles which was issued with the 
preceding number of the JourRNAL. Through Director W. T. 
Hornaday the abundant living material of the Zodlogical Park 
was placed at the disposition of the Museum for the purpose of 
making photographs for the illustrations, and through Director 
C. H. Townsend similar courtesies were extended at the New 
York Aquarium, Battery Park. The source of the illustrations 
is indicated under each figure. 
THE Department of Geology has acquired a complete series 
of the rocks and corresponding thin sections to illustrate the 
latest edition of Rosenbusch’s “Elemente der Gesteinslehre.’’ 
This collection has been placed among the study series of the 
Department, where it may be examined by those interested in 
the subject of petrography.
