COVER 



Chilean bat, Stenoderma chiknsis, from a drawing in Atlas de la 

 Historia Fisicay Politica de Chile, by Claudio Gay, vol. II, Paris, 

 1854. The two-volume set is in the Field Museum's Mary W. 

 Runnells Rare Book Room. 



Stenoderma chilensis was described by Gay from the arid 

 northern region of Chile in 1847. Because it has never been 

 observed in nature and there are no specimens of this form, its 

 existence has long been held in doubt. The distinctive nose leaf, 

 "epaulettes" on the shoulders, and lack of a tail membrane iden- 

 tify this animal as a member of the fruit bat genus Stumira, wide- 

 ly distributed in wet tropical America but unknown along the dry 

 Pacific slope of the Andes. Recently, populations of this genus 

 were discovered in arid western Peru by Victor Pacheco of the 

 Javier Prado Museum in Lima; these may be related to the enig- 

 matic form described by Gay. In 1986, Pacheco came to Chicago 

 and began study of the evolutionary relationships and distribu- 

 tion oi Stumira with Field Museum curator Bruce D. Patterson, 

 using the Museum's superb Neotropical collections. He has just 

 completed a master's program at the University of Illinois, Chi- 

 cago, in which he has learned a variety of new biochemical, ana- 

 tomical, and statistical techniques. On his return to Peru, these 

 new techniques and skills will be passed on to a new generation of 

 Peruvian scientists.
