522 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 95 
types. Eighty-four species are new to the Mexican collections of 
the United States National Museum, where all specimens collected 
during tenure of the Scholarship have been deposited. 
Most of the specimens have been incorporated in the permanent 
collections of the United States National Museum, whose numbers 
are cited herein with the abbreviation U.S.N.M. A few duplicates 
have been transferred to the E. H. Taylor-H. M. Smith collection; 
the numbers for these are cited with the symbol E.H.T.-H.M.S. 
The other duplicates are not regularly listed for all species, but where 
reference to particular specimens has been necessary the field numbers 
for them are cited following the initials H.M.S. 
Salamanders and anurans are nearly equally represented in num- 
ber of specimens, the former including 5,096, the anurans 5,258 
specimens. Of caecilians only six specimens are cataloged. 
Although reptile species far exceed amphibian species in México 
numerically, the abundance of individuals and ease of collection of 
the latter—at least at particular times in certain places—account in 
part for the proportional preponderance of number of specimens of 
amphibians over reptiles in the collection. Furthermore, about 
three-fourths of the amphibian species known from México are repre- 
sented, while of the snakes only about half the species were collected. 
Undoubtedly the abundance and ease of collection of amphibians 
have contributed greatly to the relatively large percentage of. repre- 
sentation of the Mexican fauna in this collection, yet there definitely 
is a technique peculiar even to the collection of these creatures. 
Equally as important as other factors in our favor was the aid afforded 
by Dr. E. H. Taylor, who during a month’s time escorted the junior 
author and wife on a flying and unbelievably productive visit to many 
localities previously discovered by him as ideal for the collection of 
various restricted species. Without this assistance, and without 
much other information gleaned from the same source—both in pre- 
vious collecting trips and in written or oral instruction—surely 
much less would have been taken. 
Chief among others contributing to our efforts are Mr. and Mrs. 
Dyfrig McH. Forbes, of Potrero Viejo, Veracruz, whose hospitality, 
charm, and zeal for collecting have left an indelible stamp upon 
the fruits of our years in México and upon our memories as well. 
To Dr. Doris M. Cochran we owe a debt of gratitude for patient 
and prompt attendance to our numerous requests for a checking of 
data and specimen numbers, and for ready cooperation in many other 
respects as well. Finally, Dr. Alexander Wetmore has the deepest 
appreciation of us who have benefited directly or indirectly from his 
kindly and sympathetic supervision and encouragement during 
tenure of the Scholarship, both in the field and at the U. S. National 
Museum.
