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.
