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 us. 
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. Contributors receive 50 free copies. 
Please address all requests for copies and 
inquiries to George 2ug, Division of Amphibians and 
Reptiles, National Museum of Natural History, 
Smithsonian Institution, Washington, D.C. 20560, 
U.S.A. Please include a self-addressed mailing 
label with requests.
