SMITHSONIAN 
HERPETOLOGICAL 
INFORMATION 
SERVICE 
The SHIS series publishes and distributes translations, 
bibliographies, indices, and similar items judged useful 
to individuals interested in the biology of amphibians 
and reptiles, but unlikely to be published in the normal 
technical journals. Single copies are distributed free 
to interested individuals. Libraries, herpetological 
associations, and research laboratories are invited to 
exchange their publications with the Division of 
Amphibians and Reptiles. 
We wish to encourage individuals to share their 
bibliographies, translations, etc. with other 
herpetologists through the SHIS series. If you have 
such items please contact George Zug for instructions on 
preparation and submission. Contributors receive 50 
free copies. 
Please address all requests for copies and inquiries to 
George Zug, Division of Amphibians and Reptiles, 
National Museum of Natural History, Smithsonian 
Institution, Washington DC 20560 USA. Please include 
a self-addressed mailing label with requests.
